Product Description
Tingfeng Hardware provides non-standard stamped spring contacts for encoder and sensor PCBs, manufactured from BeCu C17200 with force decay under 10% after 1 million rotation or sliding cycles, contact resistance ≤5mΩ, and tolerance of ±0.005mm. With 16 years of precision manufacturing experience, we understand that encoders and sensors demand long-term signal stability and maintenance-free operation — our spring contact solution directly serves this requirement and provides customized contact geometry design for different PCB layouts.
Product Overview
Spring contacts on encoder and sensor PCBs must maintain contact resistance without drift over millions or even tens of millions of movements, directly determining signal accuracy and system stability. Our BeCu C17200 contacts achieve precise geometry through precision stamping, stress relief heat treatment eliminates internal stress, and gold plating controls contact resistance below 5mΩ. For different PCB layouts and motion types (rotary or sliding), we provide non-standard customized spring geometry design. On the commercial side, clients increasingly focus on total cost of ownership — the value of a million-cycle contact lies in reducing downtime maintenance, extending calibration intervals, and ensuring continuous equipment operation.
