Product Description

Harwin's Gecko (G125 series) connectors provide a low-profile, dual-row cable-to-board and board-to-board interconnect solution, ideally suited for stacking and cable mating in areas where PCB real estate is at a premium.

With space and weight a consideration for many high-reliability applications, G125 connectors are designed to offer high performance in a miniature package.

Tested and proven to allow high performance in extreme conditions, the G125 family can operate within a wide temperature range (-65°C / +150°C) and under extreme vibration (Z axis 100g 6ms). This high performance is made possible by Harwin's four-finger patented (pending) Copper Alloy Contact.
