Gold-plated bellows contact spring (Servometer)
A reliable gold contact utilizing the flexible expansion and contraction of an electroplated bellows!
The precision gold-plated bellows contact springs from Servometer Inc. (USA) demonstrate high reliability in areas where issues arise with the repeatability of springs and stress due to tolerances, vibrations, and thermal expansion. The flexibility of the springs minimizes shocks and vibrations in dynamic applications while maintaining contact. The spring constant is very low, allowing for production at a required stress of 44.49g per mm. This enables designs for contacts that use delicate components and materials. The product is made with electroless nickel and is gold-plated to enhance conductivity. Most end caps are designed to fit into pins or pockets, allowing for connections to other components without soldering. **Features** - Very low self-inductance - Very low DC resistance - Very low insertion loss - High repeatability of the spring - No need for large forces to maintain contact at two points - Can be used for electrostatic discharge (ESD) protection as needed
basic information
【Contact Points】 Can be manufactured with an outer diameter of 0.020 to 0.245 in. (0.508 to 6.223 mm) 【Expected Lifespan】 A wide range of designs is possible for up to 100 to 100×10^6 cycles 【Environmental Tolerance】 ・Can be used while maintaining spring quality up to 126℃ ・No restrictions on low temperatures (currently proven in a range down to -252.7℃) 【Mounting Method】 ・In many applications, it is possible to easily insert or push the bellows opening onto a pin for installation ・The opening can also be spot welded to the pin or the contact can be soldered 【Current Rating】 Maximum current rating of 4 amperes *If the standard contact points do not meet your requirements, we will design custom contact points to match your specifications.
