M80-4222642

Headers, Receptacles, Female Sockets Overview

The M80-4222642 is a 26-position, two-row female socket connector from the Harwin Datamate J-Tek series. It features a 2.00mm (0.079 inch) mating pitch and is designed for through-hole termination. The housing is constructed from black glass-filled polyphenylene sulfide (PPS), rated UL94 V-0. Contacts are made of beryllium copper with selective gold plating on the mating interface and tin plating on the tail. 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

• High-reliability design engineered to withstand vibration, shock, and extreme temperatures.
• Selective contact plating provides corrosion resistance at the mating interface while ensuring reliable soldering.
• Integrated locking screws and polarizing keys ensure secure connection and correct alignment.

Headers, Receptacles, Female Sockets Applications

• Automotive electronic systems
• Military and defense equipment
• General industrial applications

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm pin count, row configuration, and plating specifications. Ensure the selected variant matches the required stacking height and mounting style for the target PCB layout. Confirm RoHS compliance status if environmental regulations apply to the assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a robust, high-density interconnect is required for board-to-board or cable connections. The 2.00mm pitch allows for compact layouts compared to standard 2.54mm headers. Consider the mechanical locking feature for environments subject to significant vibration or shock loads where standard friction-fit connectors may fail.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Datamate J-Tek family, known for its modular design and high performance in harsh conditions. The M80 series utilizes a unique latching mechanism that provides superior retention force compared to standard rectangular connectors. The use of PPS insulation offers excellent thermal stability and chemical resistance.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct replacement parts must match the 26-pin, 2-row configuration and 2.00mm pitch. Verify that any substitute maintains the same locking screw mechanism and contact plating specifications to ensure compatibility with existing mating hardware and environmental ratings.
