Harwin Gecko High-Reliability Connectors


1.25 mm pitch, high-reliability/high-performance connector system from Harwin

Harwin's Gecko (G125) series is a 1.25 mm pitch, high-reliability/high-performance connector system that is suited for use in environments with high vibration, shock, and extreme temperatures.

With space and weight a consideration for many high-reliability applications, G125 connectors are designed to offer high performance in a miniature package. This design means that G125 connectors achieve a 35% space saving over other high-performance connectors such as Micro-D. Through-hole and SMT options available. Available in board-to-board, wire-to-board and wire-to-wire configurations.
