M20-7820346

Overview

The Harwin M20-7820346 is a 3-position, single-row vertical socket assembly from the M20 series. It features a 2.54 mm pitch and utilizes twin-leaf phosphor bronze contacts with tin plating. Designed for through-hole installation, this board-to-board connector supports a current rating of 12A and operates within a temperature range of -55°C to 105°C. The housing is constructed from black polyamide (nylon) 6T, rated UL94 V-0. Key electrical specifications include a maximum contact resistance of 20mΩ, minimum insulation resistance of 1000MΩ, and a dielectric withstand voltage of 1000VAC.

Feature Summary

• Vertical single-row design for direct PCB mounting
• Twin-leaf phosphor bronze contacts for reliable engagement
• Polyamide 6T housing material offering high thermal stability

Applications

• Industrial control systems
• Telecommunications equipment
• General purpose interconnects

Procurement Notes

Verify the specific contact plating configuration against project requirements, as datasheets indicate availability in both gold and tin variants within the M20-782 series. Confirm that the 12A current rating aligns with the intended load, noting that some general descriptions cite lower ratings. Ensure the through-hole footprint matches the target PCB layout before ordering.

Selection Notes

Select this component when a low-profile, single-row vertical socket is required for board-to-board connections. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the operating temperature range and UL94 V-0 rating if the application involves high heat or strict fire safety standards. Verify pin count and row configuration to match the mating connector.
