Overview
The M20-7892042 is a rectangular connector from the Harwin M20 series, designed as a surface mount socket assembly. It features a single row with 20 positions and a 2.54mm pitch. The component utilizes phosphor bronze contacts with tin plating for reliable signal transmission. Rated for 3A current at 250V, it operates within a temperature range of -40°C to 105°C. The housing is constructed from black PA6T nylon with UL94 V-0 flammability rating. Designed for board-to-board applications, it employs a push-pull locking mechanism and horizontal orientation.
Feature Summary
- Push-pull locking mechanism ensures secure mating retention
- Horizontal orientation facilitates compact PCB layout integration
- Tin-plated phosphor bronze contacts provide corrosion resistance
Applications
- Board-to-board interconnection systems
- Industrial control modules requiring robust surface mount connections
- Consumer electronics utilizing high-density signal routing
Procurement Notes
Verify the specific ordering suffix against the official datasheet to confirm contact plating and packaging type. Ensure the selected variant matches the required current rating and thermal specifications for the target application environment. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability status prior to procurement.
Selection Notes
Select this component when a low-profile, single-row surface mount socket is required for board-to-board applications. Consider the 2.54mm pitch compatibility with existing header assemblies. Evaluate the horizontal mounting style against available vertical alternatives if space constraints differ. Confirm that the 3A current rating meets the circuit requirements.
Part Context
This component belongs to the M20 series, a family of connectors known for their push-pull locking system and high reliability in harsh environments. The series offers various configurations including headers, sockets, and housings in different row counts and pitches. The M20-7892042 specifically addresses needs for horizontal, surface-mounted receptacles with standard 2.54mm spacing.
Replacement Considerations
Compatible counterparts include the M20-7892046 (gold plated) and M20-7892045 (tin plated, tube packaged). Verify mechanical dimensions and electrical ratings before substitution.
