Overview
The Harwin G125-MV12605M1P is a Gecko-SL series male header connector designed for power-to-board applications. It features a 26-position configuration arranged in two rows with a 1.25 mm pitch. The component utilizes through-hole solder pin termination and operates at voltage ratings of 250 V and 450 V, with a current rating of 2 A. Constructed with phosphor bronze contacts gold-plated for conductivity, the housing is made of green polyamide (PA). It supports an operating temperature range from -65 °C to +150 °C.
Feature Summary
- Integrates internally threaded screw lock mechanism for secure mating retention
- Features vertical orientation for direct board mounting
- Utilizes gold-plated phosphor bronze contacts for reliable signal transmission
Applications
- Industrial control systems requiring secure power connections
- Automotive electronics harnesses
- Consumer appliance mainboards
Procurement Notes
Verify the specific suffix 'M1P' against the manufacturer datasheet to confirm the packing format and terminal type. Ensure compatibility with the corresponding female socket within the same Gecko-SL series. Confirm that the internal threading aligns with the locking hardware requirements of the assembly design.
Selection Notes
Select this component when a vertical male header with integrated mechanical locking is required. The 1.25 mm pitch allows for dense board layouts while maintaining 2 A current capacity. Verify that the PCB layout accommodates the through-hole pins and that the housing height fits within the enclosure constraints.
Part Context
This part belongs to the Harwin G125 Gecko-SL family, which specializes in high-reliability interconnect solutions. The series is characterized by its robust screw-lock feature, distinguishing it from standard push-pull connectors. It is engineered for environments where vibration resistance and connection stability are critical operational factors.
Replacement Considerations
Direct substitutes include other Harwin G125 series male headers with identical 26-position counts and screw-lock features. Cross-brand replacements require matching the 1.25 mm pitch, 2-row configuration, and vertical mounting style to ensure mechanical fit.
