M80-7632642

Overview

The M80-7632642 is a male header connector from the Harwin Datamate J-Tek series, designed for through-hole mounting. It features a straight orientation with 26 positions arranged in a double-row configuration. The connector utilizes a 2 mm (0.079 inch) pitch and employs solder pin termination for secure PCB attachment. Constructed with phosphor bronze contacts that are gold-plated for mating surfaces and tin-plated for tails, it ensures reliable electrical performance. The housing is made of black polyphenylene sulfide (PPS), offering UL94 V-0 flammability rating and operation within a temperature range of -55°C to +125°C.

Feature Summary

• Features fully shrouded, polarized moldings to ensure correct alignment and prevent mis-mating during assembly.
• Incorporates a robust mechanical locking system via threaded fasteners to maintain secure connection integrity under vibration.
• Utilizes a double-row design with a 2mm pitch to maximize contact density while maintaining standard board spacing.

Applications

• Industrial control systems requiring high-density signal interconnects
• Automotive electronics modules needing reliable board-to-board connections
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific suffix codes against the official Harwin datasheet to confirm exact pin count, row configuration, and termination style. Ensure compatibility with existing mating female connectors within the Datamate J-Tek family. Check for any recent Product Change Notices (PCN) regarding material composition or manufacturing location updates before finalizing procurement orders.

Selection Notes

Select this component when a double-row, through-hole male header with a 2mm pitch is required. It is suitable for applications demanding polarized, shrouded contacts and threaded locking mechanisms. Consider the operating temperature range and current ratings relative to the specific circuit requirements to ensure long-term reliability in the intended environment.

Part Context

This part belongs to the Datamate J-Tek series, a modular interconnect system by Harwin Inc. known for its versatility in space-constrained environments. The series supports various configurations including single and double rows, different mounting styles, and mating options for both signal and power applications, widely used in compact electronic designs.

Replacement Considerations

Direct substitutes include other Harwin Datamate J-Tek male headers with identical 26-position, double-row, through-hole specifications. Verify that alternative parts maintain the same 2mm pitch, polarization keying, and locking mechanism type to ensure mechanical and electrical interchangeability without redesigning the host PCB.
