Overview
The M20-7892842 is a rectangular connector socket assembly from the Harwin M20 series. It features 28 positions with a 0.100 inch (2.54 mm) pitch. The component utilizes surface mount technology in a right-angle configuration. Contact materials are phosphor bronze with gold plating on the mating interface and tin plating on the tail. The housing is constructed from black polyamide (PA6T). Rated current is 3A per contact at 250V. Operating temperature ranges from -40°C to 105°C.
Feature Summary
- Right-angle surface mount design for compact board-to-board connections
- Gold-plated contacts ensure reliable signal transmission and corrosion resistance
- Polyamide insulation provides high thermal stability and UL94 V-0 flammability rating
Applications
- High-density electronic assemblies requiring right-angle routing
- Industrial control systems with space constraints
- Consumer electronics utilizing surface mount manufacturing processes
Procurement Notes
Verify the specific suffix against official datasheets to confirm orientation and termination details. Ensure compatibility with mating header components regarding stacking height and pin count. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated environments.
Selection Notes
Select this model for applications necessitating right-angle PCB interconnects with 2.54mm spacing. Evaluate available stacking heights to ensure mechanical clearance within the enclosure. Consider the 3A current rating relative to total circuit load requirements across all active pins during operation.
Part Context
