Product Introduction

The Low-Impedance canted coil spring is a precision-engineered elastic contact element designed to create a stable, continuous conductive path between mating surfaces. Unlike traditional springs that primarily provide mechanical force, this type of canted coil spring focuses on electrical continuity, grounding stability, and electromagnetic compatibility (EMC).

Through its angled coil structure, the spring establishes multiple contact points, enabling consistent conductivity even under vibration, micro-movement, or surface irregularities. At YFS Technology (SZ) Co., Ltd, this canted coil spring is developed as part of a connector and grounding solution, helping engineers solve EMI shielding and grounding challenges in compact and high-frequency systems.

By combining elastic recovery with low contact resistance, the spring maintains reliable performance throughout repeated assembly cycles and long-term operation, making it suitable for modern electronic and electromechanical assemblies where signal integrity and electromagnetic control are critical.
