G125-MH12005M3R

Overview

The Harwin G125-MH12005M3R is a Gecko-SL series male header connector featuring a 1.25 mm pitch and 20 positions in a dual-row configuration. Designed for right-angle through-hole mounting, it utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission. The component supports a current rating of 2 A and operates within a temperature range of -65°C to +150°C. It incorporates a jackscrew locking mechanism and is housed in green polyamide (PA) insulation rated UL 94 V-0.

Feature Summary

• Features a jackscrew locking system for secure board-to-board connection
• Utilizes gold-plated phosphor bronze contacts for enhanced conductivity
• Constructed with UL 94 V-0 rated green polyamide housing

Applications

• Wire-to-board interconnections
• Right-angle PCB mounting applications
