Description
Custom Stamped Contact Shrapnel – Precision Metal Parts for IoT Sensors & Smart Home Devices
Tingfeng Hardware provides custom stamped contact shrapnel specifically engineered for IoT sensors and smart home devices. Using premium materials including phosphor bronze, stainless steel, and beryllium copper, our components are manufactured through precision stamping and bending processes to deliver reliable performance in critical applications.
Product Overview
Our contact shrapnel addresses the comprehensive requirements of IoT and smart home devices for component miniaturization, reliability, and cost-effectiveness. We utilize phosphor bronze for high conductivity and elasticity, or stainless steel for superior strength and corrosion resistance. Through precision stamping technology, we achieve consistent contact geometries and stable elastic force for optimal performance.
Product applications include sensor signal transmission contacts, battery connection springs, and device interconnect terminals. Gold or nickel plating ensures low contact resistance (≤10mΩ) and long-term oxidation resistance. Each shrapnel undergoes 100% dimensional inspection and force testing, making them suitable for smart door sensors, temperature/humidity sensors, smart plugs, security cameras, and various IoT devices.
