M80-4054242

Headers, Receptacles, Female Sockets Overview

The Harwin M80-4054242 is a Datamate J-Tek power-to-board connector featuring a female socket configuration with 21+21 positions. It utilizes a 2 mm pitch and employs vertical through-hole solder pin termination for secure board mounting. The unit incorporates reverse fix jackscrews to ensure reliable mechanical retention during mating. Constructed with beryllium copper contacts, it supports a current rating of 3 A per signal contact and withstands voltages up to 800 VAC/DC. The housing is made from black polyphenylene sulfide (PPS), providing durability within an operating temperature range of -55°C to +125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Features reverse fix jackscrews for enhanced mechanical locking stability
• Utilizes gold-plated beryllium copper contacts for reliable conductivity
• Designed with vertical through-hole solder pins for robust PCB attachment

Headers, Receptacles, Female Sockets Applications

• Industrial control systems requiring high-reliability power distribution
• Automotive electronics interfaces demanding secure board connections
• General purpose equipment needing stable signal transmission

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm the exact contact plating thickness and insulation material grade. Ensure that the reverse fix jackscrew configuration matches the assembly requirements. Cross-reference the 21+21 position count with the target PCB footprint dimensions to guarantee proper spatial clearance and alignment during installation.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a vertical orientation and high mechanical retention are critical for the application. The 2 mm pitch allows for dense packing while maintaining adequate spacing for high-voltage isolation. Consider the 3 A current rating for signal lines rather than primary power feeds. Verify compatibility with the corresponding male header from the same Datamate J-Tek series for optimal mating performance.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Datamate J-Tek series by Harwin, a modular interconnect system designed for harsh environments. The series offers various configurations including cable, board-to-board, and power-to-board options. The M80-4054242 specifically addresses applications requiring vertical mounting with secure locking mechanisms, distinguishing it from standard free-hanging or surface-mount variants in the broader product family.
