M80-8540442

Overview

The M80-8540442 is a Datamate L-Tek male board connector manufactured by Harwin Inc. It features a 2x2 contact configuration with a 2 mm pitch, designed for vertical through-hole PCB mounting. The connector utilizes phosphor bronze contacts with gold plating and a PPS housing. It supports wire-to-board and board-to-board systems, rated for 120V and 3A current.

Feature Summary

• Features fully shrouded contacts to ensure reliable mating and prevent pin damage.
• Incorporates polarized mouldings to guarantee correct alignment during assembly.
• Utilizes high-reliability four-finger beryllium copper alloy contacts for connection integrity in harsh environments.

Applications

• Wire-to-board interconnections
• Board-to-board connections
• High-load vibration applications
• Harsh environment operations

Procurement Notes

Verify the specific contact finish variant, as datasheets indicate both tin/lead and gold options exist within this series. Confirm that the required latch or friction lock mechanism matches the mechanical design requirements, noting that these add 0.5mm to the overall length calculation. Ensure the selected part aligns with the intended voltage and current ratings for the specific application context.

Selection Notes

Select this component when a vertical, latched male connector is required for compact 2x2 layouts. The Datamate L-Tek series is suitable for applications demanding high durability against shock and acceleration. Consider the stacking height variations (7.23mm to 13.51mm) when designing the mechanical enclosure and mating interface constraints.

Part Context

This part belongs to the Harwin Datamate L-Tek family, known for robust performance in demanding conditions. The M80 series specifically offers high cycle life and secure locking mechanisms. It mates with female connectors detailed in the official product documentation, ensuring compatibility within the broader ecosystem of Harwin interconnect solutions.

Replacement Considerations

Compatible female counterparts are listed on pages 21 to 24 of the official Harwin datasheet. Verify mating dimensions and polarization keys before substitution. No direct cross-manufacturer equivalents are confirmed in public data; use only verified Harwin female parts for replacement.
