Overview
The M20-7881842 is a rectangular connector from the Harwin M20 series, specifically designed as a socket assembly. It features 36 positions arranged in a dual-in-line configuration with a 2.54 mm (0.100 inch) pitch. The component utilizes surface-mount technology for PCB attachment and incorporates right-angle termination to facilitate board-to-board or cable connections. Contact surfaces are gold-plated to ensure reliable signal transmission, while the housing is constructed from black polyamide material rated UL94 V-0 for flame resistance.
Feature Summary
- Right-angle surface mount design for compact vertical interconnects
- Gold-plated contacts for enhanced conductivity and corrosion resistance
- Dual-in-line socket assembly compatible with standard header pins
Applications
- Board-to-board interconnections requiring right-angle routing
- Cable-to-board connections using mating harnesses
- High-density electronic assemblies needing reliable signal paths
Procurement Notes
Verify the specific suffix and revision level against the official Harwin datasheet to confirm right-angle orientation and contact plating specifications. Ensure compatibility with mating headers regarding stack height and pin count. Check for any recent product change notices that may affect dimensions or materials before finalizing procurement.
Selection Notes
Select this component when a right-angle, surface-mount socket is required for high-reliability applications. The 36-position capacity suits dense layouts, while the gold plating supports frequent mating cycles. Confirm that the PCB footprint matches the specified SMD pad layout and that the operating temperature range meets environmental requirements.
Part Context
This part belongs to the M20 series of connectors, known for robust performance in industrial and commercial electronics. The M20-788xx series typically denotes socket assemblies within this family, offering various position counts and mounting styles to support diverse system integration needs across multiple industries.
