Overview
The Harwin G125-MH11205M3R is a Gecko-SL series header connector featuring a 1.25 mm pitch and 20 positions in a dual-row configuration. It utilizes gold-plated phosphor bronze male pins with a 3.3 mm solder tail length for through-hole right-angle mounting. The housing is green polyamide (PA) rated UL 94 V-0, supporting -65°C to +150°C operation. Rated at 2 A per contact with 1 GOhm insulation resistance, it employs a jackscrew locking mechanism.
Feature Summary
- Patented four-finger copper alloy contacts ensure high reliability under extreme vibration conditions up to 100g.
- Jackscrew locking system provides secure board-to-board or wire-to-board connections.
- Low-profile design offers significant space savings compared to larger pitch connectors.
Applications
- Wire-to-board interconnections
- Board-to-board stacking
- High-reliability industrial electronics
Procurement Notes
