Overview
The Harwin G125-MS11205L0P is a Gecko-Latch series power-to-board header designed for surface mount technology. It features a vertical orientation with a 1.25 mm (0.049 in) pitch and a 2x6 position configuration, totaling 12 contacts. The connector utilizes male pin contacts made of phosphor bronze with gold plating. Rated for 2 A current and up to 450 VAC/DC voltage, it operates within a temperature range of -65°C to +150°C. The housing is constructed from black polyamide (PA4T) with UL 94 V-0 flammability rating.
Feature Summary
- Features a secure latch mechanism for reliable mating retention
- Designed for high-reliability power distribution applications
- Utilizes shrouded four-wall design for precise alignment
Applications
- Industrial control systems requiring robust power connections
- Telecommunications infrastructure equipment
- Automotive electronics and battery management systems
Procurement Notes
Verify the specific suffix 'L0P' against official Harwin documentation to confirm the reel packaging specification and RoHS compliance status. Ensure that the surface mount footprint matches the target PCB design guidelines provided in the manufacturer's layout data sheet before finalizing procurement orders.
Selection Notes
Select this component when a vertical surface mount solution is required for power delivery. The Gecko-Latch system offers superior mechanical stability compared to standard headers. Consider the 1.25 mm pitch constraint and the 2A current rating per contact when designing the thermal management strategy for the application environment.
Part Context
This part belongs to the Harwin Gecko-Latch family, which specializes in high-density interconnects for demanding environments. The series is characterized by its unique locking feature and compact form factor, making it suitable for space-constrained designs where vibration resistance and electrical reliability are critical performance factors.
Replacement Considerations
Direct substitutes within the same Gecko-Latch series include G125-MS11205L1P, which shares identical electrical and mechanical specifications but differs in packaging format. Verify compatibility with mating sockets such as the G125-FS11205 series before implementing any cross-reference alternatives.
