Custom Stamped Sensor Contacts – Beryllium Copper Precision Stamping for Medical Devices
Tingfeng Hardware provides custom stamped sensor contacts using beryllium copper and medical-grade stainless steel materials specifically engineered for medical devices and diagnostic instruments. Our contacts undergo precision progressive die stamping and stress relief heat treatment, achieving micron-level dimensional accuracy and ultra-low contact resistance. With 16 years of precision manufacturing experience, we deliver high-reliability stamped contact solutions for medical sensors, diagnostic equipment, and implantable devices.
Product Description
Medical device sensor contacts demand exceptional precision, reliability, and biocompatibility. Our beryllium copper contacts achieve precise contact geometries and stable elastic force through precision stamping forming. Beryllium copper offers excellent stress relaxation resistance and fatigue resistance, ensuring stable contact force and low contact resistance over millions of use cycles. Gold plating controls contact resistance below 5mΩ, ensuring accurate transmission of weak biosignals. Each contact undergoes 100% force testing and dimensional inspection, making them suitable for hearing aids, cardiac monitors, neurostimulators, and other critical medical devices.
