M80-8543442

Overview

The M80-8543442 is a Datamate L-Tek male pin header manufactured by Harwin Inc. It features a 2 mm pitch and a 34-position configuration arranged in two rows. The connector utilizes vertical through-hole solder termination for board mounting. Contact surfaces are finished with tin plating to ensure reliable electrical conductivity. The housing is constructed from black polyphenylene sulfide (PPS), providing structural integrity and thermal stability within an operating temperature range of -55°C to +125°C.

Feature Summary

• Features fully shrouded contacts and polarized mouldings to prevent misalignment during mating.
• Incorporates a vertical design suitable for direct board-to-board or wire-to-board interconnections.
• Utilizes latched construction for secure mechanical retention in high-vibration environments.

Applications

• Industrial control systems requiring robust interconnects
• Automotive electronics under harsh environmental conditions
• Medical equipment demanding high reliability

Procurement Notes

Verify the specific contact plating finish, as datasheets may list variations such as tin or tin/lead depending on production batches. Confirm that the vertical orientation matches the PCB layout requirements. Ensure compatibility with corresponding female connectors in the Datamate L-Tek series before finalizing procurement orders.

Selection Notes

Select this component when a high-density, vertically oriented header with latching capability is required. The 2 mm pitch allows for compact circuit designs while maintaining adequate spacing. Consider the tin-plated contacts for general-purpose applications where gold plating is not strictly necessary for corrosion resistance.

Part Context

This part belongs to the Datamate L-Tek series, designed for safety-critical applications involving shock, vibration, and acceleration. The series employs four-finger beryllium copper contacts to maintain connection integrity in恶劣 environments. It supports both latched and unlatched configurations for diverse mechanical needs.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek male headers with identical 2 mm pitch, 34 positions, and vertical orientation. Verify that alternative parts match the shrouded design and latching mechanism to ensure interchangeability without modifying the mating interface.
