Product Features:
  • Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
  • Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
  • Where applicable, robust circuit board design increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
  • Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
  • 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
  • 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.
