G125-MV21005L2R

Overview

The Harwin G125-MV21005L2R is a Gecko-Latch series power-to-board header featuring a 1.25 mm pitch and 10 positions (2x5). It utilizes male solder pins for vertical through-hole mounting with a straight orientation. The connector supports a current rating of 2 A per contact and voltage ratings of 250 V or 450 V. Constructed with phosphor bronze contacts gold-plated and a polyamide housing, it operates within a temperature range of -65°C to +150°C. The unit weighs approximately 413 mg and is supplied in tape and reel packaging.

Feature Summary

• Four-finger patented copper alloy contact design ensures high reliability under extreme vibration conditions.
• Gecko-Latch mechanism provides secure mating engagement for the connector system.
• Low-profile miniature package design achieves significant space savings compared to standard high-performance connectors.

Applications

• Demanding electronic product designs requiring high-reliability connections
• Applications operating within extreme temperature ranges from -65°C to +150°C
• Environments subject to extreme vibration such as Z-axis 100g testing

Procurement Notes
