M80-8500845

Overview

The M80-8500845 is a Datamate L-Tek series PCB socket assembly manufactured by Harwin. It features an 8-position (4+4) configuration with a 2 mm pitch and dual-row layout. Designed for through-hole mounting, the connector utilizes gold-plated phosphor bronze contacts rated for 3 A current and 120 V voltage. The housing is constructed from black polyphenylene sulfide (PPS) with UL94 V-0 flammability rating. It operates within a temperature range of -55°C to +125°C and supports mating stacking heights of 7.23 mm and 7.85 mm.

Feature Summary

• High-reliability four-finger beryllium copper contact design ensures connection integrity under vibration and shock.
• Durable PPS housing provides robust performance in harsh environments and high-cycle mating applications.
• Gold-plated contacts offer superior conductivity and corrosion resistance for long-term signal stability.

Applications

• Industrial control systems requiring high durability
• Automotive electronics subject to vibration and shock
• Medical equipment demanding reliable signal transmission
• Harsh environment instrumentation

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and REACH SVHC declarations prior to ordering. Ensure that the required mating stacking height aligns with the system's mechanical constraints, as this component supports specific vertical profiles. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and production lead times.

Selection Notes

Select this component when a high-density, double-row PCB socket is required for power or signal distribution. The 2 mm pitch allows for compact board layouts while maintaining adequate spacing. Consider the 3 A current rating and 120 V voltage limit to ensure compatibility with the circuit requirements. The through-hole termination method is suitable for applications needing strong mechanical anchoring on the PCB.

Part Context

This part belongs to the Datamate L-Tek family, known for its ruggedness and reliability in demanding applications. The series is designed to withstand high loads, vibrations, and accelerations without performance degradation. It is widely used in sectors where connection integrity is critical, such as automotive and industrial automation, offering a durable solution for board-to-board or wire-to-board connections.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When evaluating alternatives, ensure the replacement matches the 2 mm pitch, 8-position count, dual-row configuration, and through-hole mounting style. Verify that any substitute maintains the same electrical ratings and environmental operating temperatures.
