M80-8510442

Overview

The M80-8510442 is a Datamate L-Tek series PCB header from Harwin Inc., designed for board-to-board or wire-to-board connections. It features a 2+2 position configuration with a 2mm pitch and vertical orientation. The connector utilizes four-finger beryllium copper contacts with gold plating on the mating interface and tin/lead termination. Rated for 800V and 2.2A, it operates within a temperature range of -55°C to 125°C. The housing is black PPS, ensuring UL94 V-0 flammability rating. It employs a latched DIL design for secure mechanical retention.

Feature Summary

• High-reliability four-finger beryllium copper contact technology ensures connection integrity under harsh conditions
• Latched DIL design provides secure mechanical retention against shock and vibration
• Gold-plated mating surfaces combined with tin/lead terminations optimize conductivity and solderability

Applications

• High-load applications requiring resistance to shock and vibration
• Board-to-board interconnects in demanding environments
• Wire-to-board connections where high reliability is critical

Procurement Notes

Verify the specific ordering suffix to confirm contact finish and termination type variations. Ensure compatibility with mating connectors in the Datamate L-Tek family. Confirm that the vertical orientation and 2mm pitch align with the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when high mechanical retention and electrical reliability are prioritized over standard headers. The four-finger contact design offers superior performance in high-vibration scenarios compared to standard spring contacts. Consider the vertical form factor for space-constrained vertical stacking applications.

Part Context

This part belongs to the Datamate L-Tek series, which is engineered for high-reliability applications. The M80 series is known for its durability and ability to withstand high mating cycles without performance degradation. It is suitable for industrial and automotive sectors where environmental stress is a primary concern.

Replacement Considerations

Compatible substitutes must match the 2x2 pin count, 2mm pitch, and vertical orientation. Verify that alternative parts support the same latching mechanism and voltage ratings. Cross-reference with other Harwin Datamate L-Tek variants for equivalent mechanical and electrical specifications.
