Overview
The Harwin G125-MH25005L2P is a shrouded header connector from the Gecko-Latch MHRZ series. It features a 1.25 mm pitch and a 2x25 position configuration for a total of 50 contacts. The component utilizes male pin contacts with gold plating on phosphor bronze substrates. Designed for right-angle through-hole mounting, it includes a solder pin termination style. The housing is constructed from green polyamide material rated UL 94 V-0. Electrical specifications include a 2 A current rating and an insulation resistance of 10 GOhms. Operating temperatures range from -65°C to +150°C.
Feature Summary
- Integrated mechanical latching mechanism secures mating connections
- Shrouded design provides lateral alignment and protection
- Gold-plated contacts ensure reliable signal transmission
Applications
- Wire-to-board interconnections
- High-density PCB layouts
- Industrial control systems
Procurement Notes
Verify the specific suffix 'L2P' against official datasheets to confirm the exact latch type and housing dimensions. Ensure compatibility with mating sockets in the same MHRZ family. Confirm RoHS compliance status via the manufacturer's latest documentation before integration into regulated assemblies.
Selection Notes
Select this model when high contact density is required within a compact footprint. The right-angle orientation facilitates space-constrained board designs. Verify that the 1.25 mm pitch aligns with existing PCB silkscreen and copper pad patterns. Consider the thermal limits of the polyamide housing during soldering processes.
Part Context
This component belongs to the Harwin Gecko-Latch MHRZ series, which emphasizes secure mechanical retention. The series offers various position counts and orientations. The G125-MH25005L2P specifically addresses applications requiring robust connectivity in dense electronic assemblies.
Replacement Considerations
Substitutes must match the 1.25 mm pitch, 2x25 position count, and right-angle through-hole form factor. Verify that alternative connectors support the same 2 A current rating and operate within the -65°C to +150°C temperature range. Mechanical latching compatibility is critical for system integrity.
