G125-MH12005M4R

Overview

The Harwin G125-MH12005M4R is a Gecko-SL series male plug header featuring a 1.25 mm pitch and 20 positions in a dual-in-line right-angle configuration. It utilizes through-hole solder pin termination with gold-plated phosphor bronze contacts rated for 2 A. The connector employs a jackscrew locking mechanism and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions.
• Jackscrew board mount locking system provides secure mechanical retention for the mating housing.
• Low-profile shrouded construction offers significant space savings compared to standard high-performance connectors.

Applications

• Wire-to-board interconnections requiring high-density routing
• Electronic designs operating in environments with extreme vibration
• Applications necessitating reliable connections across wide temperature ranges

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm that the jackscrew locking feature and gold plating meet project requirements. Ensure the through-hole right-angle form factor aligns with PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this part when a robust, high-reliability connection is required in space-constrained applications. The Gecko-SL series is suitable for demanding environments due to its vibration resistance and wide thermal operating range. Consider the specific right-angle orientation and screw-locking mechanism during mechanical integration planning.

Part Context
