Overview
The Harwin M20-7883546 is a single-row PCB socket strip featuring 35 positions with a 2.54 mm pitch. Designed for board-to-board applications, it utilizes through-hole solder termination and operates at a straight orientation. The connector supports a current rating of 12A and withstands voltages up to 1kV. Constructed with bronze contacts plated in nickel-tin, the housing is made from nylon. It functions within a temperature range of -40°C to +105°C.
Feature Summary
- Features durable double-beam contacts that provide improved electrical connections and enhance overall connector reliability.
- Utilizes a compact design suitable for meeting PCB density and height limitations in space-constrained environments.
- Housing material is rated UL94V-0, ensuring high-temperature resistance compatible with standard SMT reflow processes.
Applications
- Embedded PC systems
- Motherboard interconnections
- Industrial monitoring equipment
- Communication devices
Procurement Notes
Verify the specific part number against official Harwin documentation to confirm availability status and manufacturing lifecycle stage. Ensure compatibility with mating headers regarding contact plating and mechanical stacking height requirements before finalizing procurement decisions.
Selection Notes
Select this component when a single-row, 35-position through-hole socket is required for board-to-board connectivity. Consider the 2.54 mm pitch and 12A current rating for circuit design alignment. Verify that the operating environment falls within the specified -40°C to +105°C thermal limits.
Part Context
This component belongs to the Harwin M20 series, which provides industrial-standard PCB sockets. The series offers various row configurations and position counts, serving as a standard connector solution for embedded PCs, motherboards, and large electronic systems requiring robust board-to-board interfaces.
Replacement Considerations
Consult official Harwin documentation for confirmed substitute part numbers. Generic industry equivalents may not match the specific double-beam contact geometry or UL94V-0 housing specifications required for direct replacement.
