Overview
The M20-7861142 is a surface mount socket connector from the Harwin M20 series, designed for board-to-board applications. It features 11 positions with a 2.54 mm (0.1 inch) pitch and utilizes a single row configuration. The housing is constructed from black polyamide (PA6T), meeting UL94 V-0 flammability standards. Contacts are made of phosphor bronze with gold plating on the mating interface and tin plating on the termination side. Rated at 3A per contact with a 250V rating, it operates within a temperature range of -40°C to +105°C.
Feature Summary
- Surface mount design optimized for automated PCB assembly processes
- Gold-plated contacts ensure reliable electrical performance in board-to-board connections
- High-temperature resistant PA6T insulation supports standard reflow soldering profiles
Applications
- Board-to-board interconnections in compact electronic modules
- Industrial control systems requiring high-density mounting
- Consumer electronics utilizing surface mount technology
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon order placement. Ensure storage conditions align with moisture sensitivity levels defined in the datasheet to maintain solderability prior to assembly.
Selection Notes
Select this model for applications necessitating a low-profile, single-row SMT receptacle with a 2.54 mm pitch. The choice is appropriate where space constraints limit vertical height and where robust thermal stability during reflow is required. Verify that the mating header matches the specified pin count and contact arrangement.
