M80-7532042

Overview

The M80-7532042 is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a 20-position, dual-row configuration with a 2mm (0.079 inch) mating pitch. Designed for vertical through-hole mounting, this shrouded connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin-lead plating on the tail. The housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0 for flammability. It supports a maximum current of 3A per contact and a voltage rating of 120V AC/DC, operating within a temperature range of -55°C to +125°C.

Feature Summary

• Dual-row male header design with integrated four-wall shielding for secure board-to-board or cable connections.
• Vertical through-hole termination style with a 4.5mm tail length for robust mechanical stability.
• Locking latch mechanism ensures positive retention between mating pairs during operation.
• High-temperature resistant PPS insulation material suitable for demanding industrial environments.

Applications

• Industrial control systems requiring reliable high-density interconnects
• Automotive electronics modules needing vibration-resistant connections
• Telecommunications equipment infrastructure boards
• Medical device internal circuitry connections

Procurement Notes

Verify that the specific suffix '42' corresponds to the required tin-lead contact plating, as lead-free alternatives may exist under different suffixes in the Datamate L-Tek series. Confirm that the 4.5mm tail length aligns with your PCB thickness and assembly requirements. Ensure compatibility with the corresponding female socket part numbers from the same M80-75x series to maintain proper locking engagement and electrical continuity.

Selection Notes

Select this component when a vertical, dual-row male header with a 2mm pitch is required for through-hole applications. The 20-position count fits designs needing moderate density without excessive board space consumption. Consider the 3A current rating and 120V voltage limit against your system's electrical loads. The locking latch feature makes it suitable for applications where accidental disconnection must be prevented, distinguishing it from non-latching variants.

Part Context

This part belongs to the Harwin Datamate L-Tek family, known for its compact size and high reliability in harsh environments. The M80-75x series specifically denotes vertical male headers with locking latches. As a 20-position dual-row connector, it serves as a critical interface point in multi-layer PCB architectures, bridging signal and power lines between adjacent boards while maintaining structural integrity through its shrouded design.

Replacement Considerations

M80-7532042 is a specialized variant; direct substitutes require matching the 20-position, dual-row, vertical, through-hole, and locking latch specifications. Verify pinout compatibility and physical dimensions before substitution. Generic 2mm pitch connectors may not offer the same shielding or locking mechanisms.
