Overview
The M20-7893942 is a rectangular board connector from the Harwin M20 series, designed for socket applications. It features 39 positions with a 2.54 mm (0.100 inch) pitch in a single inline configuration. The connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin termination. It is rated for a contact resistance of 20 mΩ and operates within a temperature range of -40°C to +105°C. The housing dimensions are approximately 3.92 inches in length, 0.319 inches in depth, and 0.13 inches in width.
Feature Summary
- Gold-plated phosphor bronze contacts ensure reliable signal transmission and corrosion resistance.
- Single inline horizontal socket design facilitates straightforward board-to-board interconnection.
- RoHS compliant construction supports environmentally conscious manufacturing standards.
Applications
- General purpose board-to-board connectivity
- Industrial control system interfaces
- Consumer electronics internal connections
Procurement Notes
Verify the specific contact plating combination of gold for mating and tin for termination against project requirements. Confirm that the 39-position single inline format matches the PCB footprint and mating header specifications. Ensure environmental compliance documentation aligns with target market regulations prior to finalizing procurement orders.
Selection Notes
Select this component when a high-density 39-way connection is required in a single row. The 2.54 mm pitch offers standard spacing compatibility. Consider the gold-tin plating scheme for balanced performance between contact reliability and solderability. Evaluate the horizontal orientation against available vertical space constraints on the assembly.
