G125-MH13405M3R

Overview

The Harwin G125-MH13405M3R is a Gecko-SL series header connector featuring 34 positions arranged in a dual inline configuration. It utilizes a 1.25 mm pitch and operates at right angles for through-hole mounting. The male contacts are constructed from phosphor bronze with gold plating, rated for 2 A current. The housing is made of green polyamide (PA) with UL 94 V-0 flammability rating. It supports an operating temperature range from -65 °C to +150 °C and employs a jackscrew locking mechanism.

Feature Summary

High-reliability four-finger copper alloy contact design ensures stable performance under extreme vibration conditions.
Jackscrew locking system provides secure mechanical retention between mating connectors.
Low-profile miniature package offers significant space savings compared to standard high-performance connectors.

Applications

Demanding industrial electronic applications requiring high reliability
Extreme environment systems with wide temperature variations
Vibration-prone equipment installations

Procurement Notes

Verify the specific suffix codes against official Harwin documentation to confirm exact pin count, orientation, and packaging details. Ensure compatibility with mating sockets within the Gecko-SL family. Confirm RoHS compliance status via the latest datasheet before integration into regulated products.

Selection Notes

Select this component when a right-angle through-hole male header with 1.25 mm pitch is required. It suits designs needing robust vibration resistance and high current capacity per contact. Verify board space constraints align with the low-profile geometry and check mating interface requirements for jack screw retention.

Part Context

This part belongs to the Harwin Gecko-SL family, designed for high-performance connectivity in compact spaces. The series features patented four-finger contacts and operates reliably across extreme temperatures and vibrations. It serves as a critical interconnect solution for demanding electronic environments where signal integrity and mechanical stability are paramount.
