M80-8940305

Overview

The Harwin M80-8940305 is a Datamate L-Tek series rectangular connector socket, designed for board-to-board or cable applications. It features a 2.00mm (0.079 inch) mating pitch with 3 positions in a single row configuration. The component utilizes female crimp contacts made of beryllium copper, finished with gold plating for reliable signal transmission. The housing is constructed from black thermoplastic material, rated UL94 V-0 for flammability. Electrical ratings include a current capacity of 3A and a voltage rating of 300V. The operating temperature range spans from -55°C to +125°C, ensuring stability in demanding environments.

Feature Summary

• High-reliability four-finger beryllium copper contact design ensures secure retention under vibration and shock.
• Fully enclosed housing structure protects internal contacts from environmental contaminants.
• Integrated polarization keying mechanism prevents misalignment during mating cycles.
• Compact 2mm pitch design supports high-density interconnect requirements.

Applications

• Military and aerospace electronic systems
• Medical instrumentation devices
• Industrial automation equipment
• Robotics control modules

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm contact type, housing style, and termination method. Ensure compatibility with mating header components within the same Datamate L-Tek family. Confirm that the selected variant meets the required environmental certifications for the target application. Cross-reference the part number with the manufacturer's latest documentation to avoid obsolete specifications.

Selection Notes

Select this component when a compact, high-reliability cable-to-board interface is required. The 2mm pitch allows for dense packing in space-constrained designs. Verify that the mating environment does not exceed the 300V voltage or 3A current limits. Consider the thermal range of -55°C to +125°C for extreme condition suitability. Ensure proper crimping tools are available for the specified wire gauge compatibility.
