M80-4200442

Headers, Receptacles, Female Sockets Overview

The M80-4200442 is a Datamate J-Tek series receptacle connector manufactured by Harwin Inc. It features a 4-position configuration with two rows, designed for vertical through-hole mounting on printed circuit boards. The connector utilizes a 2.00mm pitch and incorporates jackscrew locking mechanisms for secure mating. Contact surfaces are gold-plated to ensure reliable signal transmission, while the housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, offering UL94 V-0 flammability rating. It supports a rated voltage of 120V and operates within a temperature range of -55°C to +125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Vertical through-hole mounting style with jackscrew locking for secure board attachment
• Gold-plated female contacts ensuring high reliability in signal transmission
• Glass-fiber reinforced PPS insulation providing thermal stability and flame resistance

Headers, Receptacles, Female Sockets Applications

• Industrial control systems requiring robust interconnects
• Automotive electronics applications
• Military and defense equipment

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix to confirm pin count, contact plating, and tail length variations. Ensure compatibility with corresponding male headers from the same Datamate J-Tek family. Confirm that the vertical orientation and jackscrew mechanism align with the mechanical constraints of the target assembly design.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-reliability vertical connector is required for space-constrained PCB layouts. The 2.00mm pitch allows for dense packing compared to larger standard pitches. Consider the jackscrew feature if vibration resistance is critical, as it provides superior retention compared to friction-lock designs.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Datamate J-Tek family, known for its high-reliability performance in harsh environments. The M80-420xx series specifically denotes vertical receptacles with jackscrew locks. It complements the broader Harwin connector portfolio by offering a compact solution for board-to-board or cable-to-board connections where secure locking is mandatory.

Headers, Receptacles, Female Sockets Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Cross-reference with other Harwin M80-42xxxx models for similar pitch and locking styles, but verify mechanical dimensions and electrical ratings carefully before substitution.
