M50-3612042

Headers, Male Pins Overview

The M50-3612042 is a surface mount header connector from the Harwin Archer M50 series. It features 40 positions arranged in two rows with a 1.27mm (0.050 inch) pitch. The connector utilizes male pins with square contact shapes and brass material, finished with gold plating on mating surfaces and tin on tails. Rated for 1A current and 250V, it operates within a temperature range of -55°C to 105°C. The housing is black thermoplastic rated UL94 V-0, designed for board-to-board or cable applications without a cover.

Headers, Male Pins Feature Summary

• Surface mount design compatible with pick-and-place automation
• Push-pull locking mechanism for secure connection
• Gold-plated contacts ensure reliable signal transmission

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board assemblies
• High-density electronic modules

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' against the requested model number, as datasheets may list variants with different packaging or termination styles. Confirm that the 1.27mm pitch and 40-position count match the target PCB footprint. Ensure the operating temperature range of -55°C to 105°C meets environmental requirements. Check for RoHS compliance status if required by project specifications.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-reliability header is needed for SMT assembly. The 1.27mm pitch allows for dense routing compared to standard 2.54mm headers. The push-pull feature provides mechanical stability without screws. Consider the 1A rating per contact for power distribution limits. Verify that the square pin shape aligns with the mating socket orientation.

Headers, Male Pins Part Context

This part belongs to the Archer M50 family, known for high-reliability interconnects. The series offers various configurations including vertical and horizontal orientations. The M50-3612042 specifically denotes a 40-position, 2-row header. Harwin designs these connectors for demanding industrial and commercial applications requiring robust performance.

Headers, Male Pins Replacement Considerations

Direct substitutes include other 40-pin, 1.27mm pitch SMD headers from manufacturers like Samtec or Molex, provided they support push-pull locking. Verify that alternative parts maintain the same UL94 V-0 flammability rating and 1A current capacity. Ensure the mating interface dimensions are identical to prevent assembly issues.
