G125-MS11205L1P

Overview

The Harwin G125-MS11205L1P is a Gecko-Latch series board-to-board or cable header connector featuring a 1.25mm pitch and 12 positions in a dual-row configuration. It utilizes surface mount termination with gold-plated phosphor bronze contacts rated for 2A current and 450VAC/DC voltage. The component employs a four-wall shrouded design with pin-locking features and a board lock characteristic. Constructed from black polyamide (PA4T) insulation with UL94 V-0 flammability rating, it operates within a temperature range of -65°C to +150°C.

Feature Summary

• Four-wall shrouded housing provides comprehensive contact protection and alignment
• Pin-locking mechanism secures mating connections against vibration
• Board lock feature ensures stable mounting on the substrate
• Gold-plated phosphor bronze contacts ensure reliable conductivity

Applications

• High-density board-to-board interconnections
• Cable-to-board assembly applications
• Industrial control system power distribution
• Automotive electronic module connections

Procurement Notes

Verify that the specific ordering suffix matches the required termination style and packaging format. Confirm that the four-wall shrouding and pin-locking requirements align with the mechanical design constraints. Ensure compatibility with the specified 1.25mm mating pitch and verify that the operating temperature range meets the environmental conditions of the final application before procurement.

Selection Notes

Select this component when a robust, high-reliability connection is required for space-constrained designs. The Gecko-Latch series offers superior retention force compared to standard headers. Consider the surface mount profile and the specific insulation height of 4.90mm during PCB layout planning. Ensure mating connectors are compatible with the male pin type and the defined electrical ratings.

Part Context

This part belongs to the Harwin Gecko-Latch family, designed for demanding industrial and automotive environments. The series emphasizes secure locking mechanisms and high thermal stability. The G125-MS11205L1P specifically addresses needs for vertical surface mount headers requiring enhanced mechanical security and electrical performance in compact form factors.

Replacement Considerations

Direct substitutes within the same Gecko-Latch series include variants with different row counts or terminal styles. Verify mechanical footprint compatibility and electrical ratings when considering alternative part numbers. Cross-reference mating connector specifications to ensure interface consistency.
