Overview
The G125-MH15005M4P is a male plug header connector from the Harwin Gecko-SL series. It features a 1.25 mm (0.049 inch) pitch and a 25+25 position configuration across two rows. The component utilizes a right-angle through-hole mounting style with solder pin terminals. Key mechanical features include Screw-Lok board mount locking and DIL form factor. The housing is constructed from polyamide material rated UL 94 V-0, with gold-plated phosphor bronze contacts ensuring reliable electrical performance.
Feature Summary
- Screw-Lok threaded locking mechanism for secure board attachment
- Right-angle through-hole termination for PCB integration
- Gold-plated phosphor bronze contacts for conductivity
- Polyamide housing with UL 94 V-0 flammability rating
Applications
- Industrial control system interconnects
- Automotive electronics modules
- Telecommunications equipment backplanes
- Medical device signal routing
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status and REACH SVHC declarations prior to procurement. Ensure that the required screw-locking hardware is included or sourced separately as per assembly requirements. Confirm that the right-angle orientation matches the PCB layout constraints. Validate that the through-hole soldering process parameters are compatible with the terminal design.
Selection Notes
Select this part when a secure, vibration-resistant connection is required in space-constrained applications. The right-angle profile facilitates dense PCB layouts while maintaining serviceability via the screw-lock feature. Consider the 1.25 mm pitch for balancing contact density and handling ease. Ensure mating connectors match the female socket specifications of the Gecko-SL family.
Part Context
This component belongs to the Harwin Gecko-SL series, designed for high-reliability applications requiring robust mechanical retention. The series emphasizes secure connections through threaded locking mechanisms rather than standard latches. It serves as a male header counterpart to various female sockets within the same ecosystem, supporting diverse industrial and automotive connectivity needs.
Replacement Considerations
Compatible substitutes include other Gecko-SL male headers with identical 1.25 mm pitch, 50-position count, right-angle orientation, and through-hole termination. Verify that alternative parts maintain the Screw-Lok locking feature and similar housing material ratings to ensure mechanical and thermal compatibility.
