M80-8544442

Overview

The M80-8544442 is a Datamate L-Tek series male header connector manufactured by Harwin. It features a double-row configuration with 44 positions (22+22) and a 2 mm pitch. Designed for through-board termination, it utilizes solder pin contacts with tin plating. The unit includes latches for secure mating and employs PPS housing material. Rated for 120V and 3A, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• High-reliability four-finger beryllium copper contact technology ensures connection integrity under harsh conditions.
• Latched design provides secure mating in high-load vibration, shock, and acceleration environments.
• Durable construction supports high mating cycles without performance degradation.

Applications

• Safety-critical applications requiring robust mechanical retention
• Environments subject to high vibration and shock loads
• Board-to-board and wire-to-board interconnections

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm latch inclusion and contact plating specifications. Ensure the selected variant matches the required orientation and termination style for the target PCB layout. Cross-reference the part number with current RoHS compliance documentation to meet regulatory standards.

Selection Notes

Select this component when a latched, double-row male header with 2 mm pitch is required for through-hole mounting. Consider the 3mm tail length and PPS housing properties for thermal and mechanical stability. Evaluate the 120V/3A ratings against circuit requirements to ensure adequate electrical clearance and capacity.

Part Context

This part belongs to the Datamate L-Tek family, designed for demanding industrial and aerospace sectors. The series emphasizes durability and high-cycle reliability using proprietary contact technology. It serves as a standard solution for secure interconnects where mechanical locking is essential for operational safety.

Replacement Considerations

Consult the Harwin cross-reference guide for compatible alternatives. Verify that any substitute maintains the 2 mm pitch, 44-position count, and latching mechanism to ensure mechanical interchangeability.
