M80-8531042

Overview

The M80-8531042 is a Datamate L-Tek series male PCB header featuring a 2mm pitch and 10 contacts arranged in a dual inline (DIL) configuration. It utilizes gold-plated phosphor bronze contacts within a black UL94V-0 polyamide housing. Designed for vertical through-hole mounting, this connector supports board-to-board and wire-to-board systems with a rated voltage of 120V and current capacity of 3A. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Fully shrouded contact design ensures reliable mating and environmental protection
• Polarized mouldings prevent incorrect insertion during assembly
• Gold-plated phosphor bronze contacts provide durable electrical performance
• Vertical PC tail configuration facilitates standard through-hole PCB installation

Applications

• High-reliability industrial equipment interconnections
• Board-to-board connections in harsh environments
• Wire-to-board assemblies requiring secure locking

Procurement Notes

Verify the specific Datamate L-Tek variant against official Harwin datasheets to confirm compatibility with mating female connectors. Ensure that the polarized keying matches the target application requirements. Cross-reference the contact plating thickness and housing material specifications with project constraints to guarantee long-term reliability under specified thermal and mechanical conditions.

Selection Notes

Select this component when a robust, high-cycle connector is required for demanding applications. The Datamate L-Tek series offers superior retention force compared to standard headers. Consider the 2mm pitch and dual-row layout for space-constrained designs needing high pin counts. Verify that the 3A current rating aligns with the circuit load requirements.

Part Context

This part belongs to the Datamate L-Tek family, engineered for safety-critical and high-vibration environments. The series is characterized by its four-finger beryllium copper contacts, which maintain connection integrity under shock and acceleration. It is widely used in aerospace, defense, and medical devices where failure is not an option.

Replacement Considerations

Compatible mating parts are listed in the official Harwin Datamate catalog pages 21 to 24. Ensure any substitute maintains the same 2mm pitch, 10-position count, and polarization scheme to preserve mechanical and electrical interface integrity.
