G125-MV23405L0R

Overview

The G125-MV23405L0R is a Gecko-SL series male header connector manufactured by Harwin Inc. It features a 1.25 mm pitch and a 2x17 position configuration, totaling 34 contacts. The component utilizes phosphor bronze contacts with gold plating and a polyamide (PA4T) housing rated UL94 V-0. Designed for vertical through-board mounting, it supports a current rating of 2 A per contact and voltage ratings of 250 V or 450 V. The operating temperature range spans from -65 °C to +150 °C.

Feature Summary

• Patented four-finger contact design ensures reliable electrical connection under high vibration and shock conditions
• Integrated board lock mechanism provides secure mechanical retention during mating cycles
• Compatible with automated pick-and-place assembly processes via tape and reel packaging

Applications

• High-reliability power distribution systems requiring robust interconnects
• Industrial control units exposed to significant mechanical stress
• Automotive electronics demanding stable performance across wide temperature ranges

Procurement Notes

Verify the specific suffix 'L0R' against official datasheets to confirm the exact packing quantity and reel specifications. Ensure that the required board lock feature aligns with the design intent, as some variants may differ in locking mechanisms. Cross-reference the pin count and pitch requirements with the target PCB layout to guarantee compatibility with mating connectors.

Selection Notes

Select this component when a male header with integrated board locking is necessary for high-vibration environments. The Gecko-SL series offers superior retention compared to standard headers. Consider the 1.25 mm pitch constraints and verify that the 2 A current rating meets the circuit requirements without derating issues at elevated temperatures.
