Overview
The M20-7872242 is a dual-entry socket assembly from the Harwin M20 series, designed for surface mount technology. It features a 44-position configuration with a 2.54 mm pitch and two rows of contacts. The connector supports bottom or top entry for mating pins and utilizes solder termination for PCB attachment. This component is intended for general purpose, industrial, and telecommunications applications requiring reliable board-to-board or wire-to-board interconnections.
Feature Summary
- Dual-entry receptacle design allowing flexible pin insertion from either side
- Surface mount construction for automated PCB assembly processes
- High-density 44-position layout within a standard 2.54 mm grid
Applications
- General purpose electronic interconnects
- Industrial control system wiring
- Telecommunications equipment connections
Procurement Notes
Verify current availability status as distribution channels may vary. Confirm that the specific dual-entry variant matches the mechanical requirements of the mating harness. Ensure compatibility with standard SMT reflow profiles and check for any recent product change notifications regarding material composition or packaging updates before finalizing procurement orders.
Selection Notes
Select this part when high pin density is required in a compact footprint without sacrificing access flexibility. The dual-entry feature simplifies wiring in confined spaces where cable routing from only one side is difficult. Ensure the mating pin length and header height align with the stack-up requirements of the target assembly to guarantee proper engagement.
Part Context
This component belongs to the M20 series, which offers various pitch options and entry styles. The M20-7872242 specifically addresses needs for high-count connections in space-constrained environments. It complements other M20 headers and sockets, providing a standardized solution for robust signal and power transmission in demanding operational settings.
