Camshaft position sensors: What distributors/resellers should look for in a global supplier for aftermarket and original-equipment (OE) sales & procurement
One of the biggest challenges facing OEM and aftermarket parts distributors worldwide is finding a reliable and qualified supplier, distributor, or importer. That is especially the case if you are trying to reach other international distributors, resellers, or procurement officers who are not based in your region of the world or where your supply base is based. With so many unscrupulous or marginal players in all parts sectors, it is more important than ever for distributors to know what to look for and to ask the right questions, as well as to understand and articulate the best practices as well as the appropriate industry standards from the points of view of the distributor/reseller.
The following white paper is dedicated to one of our product families, the camshaft position sensors, and is meant to provide a deep-dive into some of the most critical elements that should be taken into consideration by any distributor/reseller when evaluating potential manufacturers/suppliers, as well as outlining the key topics in regard to proper product qualification and effective long-term partnership development.
- The global aftermarket and OE supply landscape:
1.1. Market segmentation and regional demand for camshaft position sensors
When it comes to camshaft position sensor families and specific product lines, the OEMS and aftermarket global supply landscape can be defined by various market segments. It can be regional markets, specific industry applications, and other factors. Knowing them as well as the potential demands from the point of view of global distributors and resellers is crucial to successful product development, targeting the right product mix, and ensuring market penetration.
For instance, while it is fair to say that the majority of Tier 1 and Tier 2 camshaft position sensor volumes come from North America and Western Europe where current in-use vehicle fleet mix and future regulatory (e.g., emissions) demands allow for sophisticated engines and more advanced on-board diagnostic (OBD) tools and connectivity, emerging markets, such as Latin America, Southeast Asia, and Eastern Europe, continue to expand and are also price-sensitive and require durable direct-fit products.
The demand for aftermarket camshaft position sensors typically comes from wholesale and online distributors of OE parts, local and mobile repair shops and mechanics, chain automotive retailers, etc. In the OEs market, OEMs such as General Motors, Ford, Stellantis, and Volkswagen are the most significant customers that drive annual production volumes, as well as R&D and product program investments and development cycles. OEMs typically require high-quality, approved parts that have all the right product specifications and are able to provide a consistent supply.
1.2. The tiers of the supplier network for camshaft position sensors and their role
The supplier landscape can be seen in multi-tier tiers that are needed to bring a camshaft position sensor or a similar module to market:
? Tier 1 is a module production itself and requires specific component sub-suppliers (specialty magnetics, semiconductors, and special plastics, among other suppliers)
? Tier 2 is various sub-suppliers of raw materials and components for Tier 1 manufacturers
? Tier 3, in turn, are raw-material suppliers
Tier 1 is, in its turn, usually consolidated through rigorous supplier-qualification and purchasing-professionals-sourcing processes. Most Tier 1 suppliers manage their own direct multi-tier supplier network with a single-source strategy whenever possible and with only a limited number of backup suppliers to limit their risks of supply chain disruptions.
1.3. Distributors and resellers in the camshaft position sensor global supply network
The relationship between the distributor or reseller and the global supplier (manufacturer) is also a critical one and can be the point of difference in many competitive parts categories, especially in high-volume automotive products. Distributors and resellers provide three main values to OEMS, global suppliers, and product brands:
? Market expertise on regional markets, vehicle parc, workshop practices, price points, etc.
? Training and support for the installation and technical specs
? Logistics customization and fulfillment localization
A global supplier can engage with the distributors and resellers at the very early stages of product development and qualification and provide region-specific packaging, technical documentation, and marketing and sales materials.
- The camshaft position sensor technical and regulatory requirements
2.1. Typical performance specifications for camshaft position sensors in automotive applications
Camshaft position sensor technical specifications should be guided by the following performance parameters:
? Temperature range (tolerance): for example, ¨C40 ¡ãC to +150 ¡ãC or more if the engine room environment requires extended temperature range components to function properly
? Signal amplitude and frequency switching threshold: typically voltage or digital square waveform
? Vibration and shock resistance: as specified in ISO 16750, or as per specific OEM durability and road-test protocols
? Environmental resistance (weather sealing): typically IP67 or higher per IP-code
Note: Any serious reseller or procurement manager should not simply accept the vendor¡¯s part datasheet at face value but should request full technical documentation, third-party test reports, as well as certification of the production process and equipment.
2.2. On-board diagnostics and additional features for camshaft position sensors in modern ECUs
Increasingly, in their effort to meet ever more stringent emissions and other performance standards, engine-control units are starting to integrate additional on-board diagnostics to key components in addition to the engine and catalytic converter management software. A number of these features are also becoming common in traditional starter-alternator-battery ignition systems such as integrating OBD features that can include voltage and signal open detection, signal amplitude, and drift monitoring, and other issues as well as wireless connectivity for remote diagnosis and smartphone apps, etc. With the correct electronic components integrated into a camshaft position sensor, including a dedicated ASIC, global suppliers can start to support this market development and ensure that distributors and resellers can support these features through proper training.
2.3. The international standards and regulatory compliance for camshaft position sensors
Exporting automotive components is also associated with many different certifications and regulatory-compliance requirements, and there are no specific ones for camshaft position sensors except the very generic safety and electrical standards for industrial products (IEC/EN61000-4-2, IEC/EN61000-4-5, etc.). However, in most countries and especially if a global supplier¡¯s distribution channel requires sales in the EU, the following standards and regulations are key:
? Electromagnetic compatibility (EMC) emission requirements as per CISPR 25, FCC Part 15, or other regulatory requirements
? Restricted substances such as RoHS and REACH in the EU, as well as REACH in many other countries
? Vehicle on-board diagnostic systems standards (OBD II in North America and EOBD in the EU, along with many similar requirements in Asia-Pacific and other regions)
? Quality-management systems (IATF 16949)
The best practices in supplier selection and qualification
3.1. The most important criteria and KPIs when qualifying camshaft position sensor vendors
Supplier qualification is a process that is typically started by purchasing and/or quality-management professionals and teams within OEMS or by a distributor or reseller when evaluating different manufacturing vendors. For Tier 1 suppliers, such a qualification process may include the following steps:Verification of existing registrations and/or certifications (ISO 9001, IATF 16949, etc.) as well as full audit and remediation action reports.
Evaluation of production capacity and scalability for a particular part or module production and for the market segments of interest to the buyer.
Available and ongoing investments in R&D and product technology development, including alternative technologies, materials, miniaturization, or special tools, etc.
Supplier risk scoring, credit analysis, and financial-stability evaluation.
Typically, there is also a stage-gate process to approve each of the steps and suppliers often get to know potential end customers through third-party business-matchmaking or B2B networking events.
3.2. Sampling and pilot runs
A formal qualification process is often followed by the small pilot runs to confirm production consistency and qualification as well as to ensure that the vendor¡¯s tooling and engineering are fully aligned with the part numbers, specifications, and packaging selected by the customer.
3.3. Contract negotiation and terms, conditions, and SLAs
Contract negotiations will focus on pricing and pricing tiers for annual minimum volume commitment, as well as defined service-level agreements (SLAs) that are agreed between the OEM and the Tier 1 supplier (SLAs between distributors and manufacturers are also common). Other typical points include warranty coverage for material and workmanship as well as clear return-material-authorization (RMA) process and terms.
- Quality control and traceability
4.1. Incoming inspection and testing
Incoming quality control (IQC) typically performed by OEMs and distributors can include visual inspections for corrosion and any potential damage during shipment as well as electrical testing of signal amplitude and switching threshold as well as overall noise immunity.
4.2. Production line quality controls
Inline quality controls performed during the production can include automated visual inspection (AVI) to ensure proper component placement and alignment, connector placement and tightness, as well as functional testing using a mechanical part that simulates a rotating reluctor wheel or disk at various speeds (idle, half-throttle, full-throttle, etc. ).
4.3. Final acceptance tests and environmental testing
Environmental tests such as thermal shock, salt spray/humidity testing, and vibration to various frequency ranges are required to simulate the real-world vibration and operating temperatures, as well as any potential shock.
4.4. Lot tracking and serialization
The key elements of effective traceability practices in case of field returns or RMA warranties are associated with specific part numbers for individual production lines and include lot or batch numbers and date codes.
- Logistics and distribution for camshaft position sensors
5.1. Inventory management models
Consignment stock programs, just-in-time (JIT) inventory, and vendor-managed inventory (VMI) are some of the most common inventory management models used by global distributors and manufacturers.
5.2. Packaging, shipping, and freight optimization
A typical approach to international freight is to develop packaging that can be easily palletized for transit to key destinations in both export and import and to try to consolidate freight whenever possible to make full container loads (FCL) to reduce the freight rates.
5.3. Customs compliance and duties
Correct HS coding and classification of camshaft position sensors for import and export and having the correct certificates of origin are also needed for any global shipments to comply with import and export controls of both supplier and distributor/importer countries.
- Risk management and business continuity planning
6.1. Supply-chain redundancy and diversification
Supply-chain redundancy can include qualification of multiple production sites as well as secondary or backup suppliers for key subcomponents and parts to ensure supply continuity, as well as proper safety-stock buffers.
6.2. Monitoring regulatory and geopolitical changes
Supply-chain risk-management should also include close monitoring of regulatory as well as geopolitical developments such as export/import restrictions and trade policy changes to stay ahead of possible restrictions or increased costs of transportation.
6.3. Cybersecurity and data protection
Global supply chains are highly interconnected, and all companies rely on digital data, documentation, and systems to share information. Ensuring that intellectual property and data privacy are also appropriately protected is a critical function of cybersecurity and is typically combined with data-integrity assurance.
- Value-added services for distributors and resellers
7.1. Technical support and installation training
Effective technical support can be a critical differentiator for suppliers who have the knowledge and resources to share with customers. This can include in-country installation workshops, product demonstration, and diagnostic trainings as well as online support and training.
7.2. Marketing and branding support
Co-branding, if this is allowed under the global supplier¡¯s quality-management systems and IP or trade-mark registration, as well as joint marketing, sales and technical-support material development and production are other examples of effective value-added services for distributors and resellers.
7.3. After-sales service and warranty management
Online portals for the management of RMA, efficient return processing with access to advanced replacement, RMA tracking and documentation are the most common ways that aftermarket suppliers support their distribution channel partners and R&D and product program investments and development cycles. OEMS may require their distributor partners to have a minimum number of years of in-country presence and other requirements to be a trusted partner.
