M20-7832046

Overview

The Harwin M20-7832046 is a 40-position, dual-row female socket assembly designed for board-to-board applications. It features a 2.54 mm (0.1 inch) pitch and utilizes through-hole solder termination for secure PCB mounting. The connector operates within a temperature range of -40°C to +105°C and supports a current rating of 12A. Constructed with a nylon housing and phosphor bronze contacts, it offers reliable electrical performance in industrial environments.

Feature Summary

• Dual-beam contact design provides improved electrical connection stability
• High-temperature liquid crystal polymer housing withstands SMT reflow processes
• Compact form factor accommodates high-density PCB height restrictions

Applications

• Industrial control systems requiring robust board-to-board interconnects
• Telecommunications equipment with high-density PCB layouts
• General-purpose electronic assemblies needing reliable signal transmission

Procurement Notes

Verify the specific pin count and row configuration against the target PCB footprint before ordering. Confirm that the through-hole termination style matches the manufacturing process capabilities. Ensure the operating temperature range aligns with the environmental conditions of the final application to maintain long-term reliability.

Selection Notes

Select this component when a 2.54 mm pitch dual-row female connector is required for vertical board stacking. Consider the 12A current rating and -40°C to +105°C operational limits for suitability. The nylon housing and nickel-tin plating offer standard durability for general industrial use cases.

Part Context

This part belongs to the Harwin M20 series, which provides industrial-standard 2.54 mm pitch connectors. The series is engineered for high-density applications, offering various configurations including surface mount and through-hole options. The M20-7832046 specifically addresses needs for robust, vertically mounted dual-row interfaces.

Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 40-pin dual-row configuration, and through-hole termination. Verify compatibility with existing PCB footprints and housing dimensions. Ensure equivalent current ratings and temperature specifications are maintained for functional interchangeability.
