Hyperspring

Technology

Snaptac

product range is equipped with Hyperspring

contacts combining our high-reliability hyperboloid

contact technology, with the mechanical features of a spring-loaded contact, to produce interconnections with

improved signal integrity, high reliability and current density, and proven parametric stability over time.

A key innovation within the Snaptac

connector range is in the design of the spring loaded contact. For the first

time, a hyperboloid socket has been combined with a spring loaded plunger to provide a compressible contact.

This arrangement enables the characteristics of very low and stable contact resistance, high current carrying

capability, and extremely low wear mechanisms for extended operation over time to be realised within a

sealed while unmated connector system. This unique combination enables the spring loading characteristic

to be determined separately from the electrical characteristics thus optimising the mechanical, electrical and

environmental performance.
