Precision Stamped Contacts for Medical Sensors – Stainless Steel & Phosphor Bronze
Tingfeng Hardware specializes in medical-grade precision stamped contacts, using stainless steel and phosphor bronze materials for medical sensors, diagnostic equipment, and patient monitors. Contacts are processed through precision progressive die stamping and finishing treatments to ensure stable electrical performance and long-term reliability. With 16 years of precision manufacturing experience, products comply with ISO 9001 and RoHS standards.
Product Description
Medical sensor contacts require ultra-low contact resistance and long-term signal integrity in miniature dimensions. Our precision stamped contacts use phosphor bronze (C5191) or medical-grade stainless steel (304/316L), achieving one-step forming of complex geometries through precision progressive die stamping. Gold or silver plating surface treatment stabilizes contact resistance below 5mΩ, ensuring accurate biosignal transmission. Each contact undergoes 100% dimensional inspection and continuity testing, meeting the stringent reliability and consistency requirements of medical devices. From material batch traceability to finished product inspection, we implement a complete medical-grade quality control system.
