Canted Coil & Spring Contact Fingers
Loose elliptical canted coil rings and spring contact fingers, silver- or gold-plated, for EMI, grounding and interconnection. Material options: C17200/C17500/C18150 beryllium copper, other copper alloys, stainless steel and special alloys. Plating: gold, silver, tin, nickel. Minimum inner diameter 1.5 mm (customizable); minimum wire diameter 0.1 mm. Both radial-compression and axial-compression coil types are available.
View familySpring-in-Spring Sockets
Socket structures with two nested springs (SIS) for high-reliability, low-insertion-force connections. Advantages include high contact power density / multi-point contact, service life up to 100,000 insertion cycles, easy installation and replacement, high current-carrying capacity with low temperature rise, low insertion and extraction force, low voltage drop, and high vibration and shock resistance.
View familyTorsion Spring Jacks / Sockets
Torsion-spring socket structures for precise, durable contact under repeated use. Available in socket sizes from 1.0 mm to 18.0 mm with matched pin diameters; working currents from 10 A to 700 A, contact resistance from 4.5 mΩ down to 0.1 mΩ.
