M50-3503842

Headers, Male Pins Overview

The Harwin M50-3503842 is a board-to-board or cable header connector featuring 76 positions arranged in two rows. It utilizes a 1.27 mm (0.05 inch) pitch with straight male pin contacts made of phosphor bronze and gold plating. Designed for surface mount technology, it employs a solder terminal interface. The housing is constructed from black liquid crystal polymer (LCP), ensuring UL 94 V-0 flammability rating. The component operates within a temperature range of -40°C to +105°C and supports a current rating of 1 A per contact.

Headers, Male Pins Feature Summary

• High-density 76-position configuration in a dual inline layout
• Surface mount installation style with mounting pegs for stability
• Gold-plated phosphor bronze contacts for reliable signal transmission
• UL 94 V-0 rated LCP insulator for thermal and fire resistance

Headers, Male Pins Applications

• Compact electronic assemblies requiring high I/O density
• Board-to-board interconnections in space-constrained designs
• Cable-to-board connections using ribbon cables
• Industrial control modules and communication equipment

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm exact pin count, termination type, and packaging format. Ensure compatibility with automated pick-and-place equipment due to the SMT mounting style. Confirm RoHS compliance status and lead-free requirements prior to procurement to meet environmental regulations.

Headers, Male Pins Selection Notes

Select this connector when a 1.27 mm pitch dual-row header is required for surface mount applications. Consider the 1 A current rating and -40°C to +105°C operating range for suitability in industrial environments. Verify that the PCB footprint matches the specified dimensions and that the gold plating meets the necessary cycle life requirements for mating cycles.
