M50-3903942

Headers, Male Pins Overview

The M50-3903942 is a Harwin Archer M50 series socket connector featuring a 1.27 mm pitch and dual-row configuration with 38 positions. It utilizes phosphor bronze contacts with gold plating for reliable signal transmission. The housing is constructed from black polybutylene terephthalate (PBT), rated UL94 V-0, supporting operating temperatures from -40°C to +105°C. Designed for through-hole mounting, it employs a push-pull locking mechanism to ensure secure mating. The unit is rated for 1A current and 1kV voltage, suitable for board-to-board and wire-to-board applications.

Headers, Male Pins Procurement Notes

Verify the specific pin count and row configuration against project requirements before ordering. Confirm that the push-pull locking style matches the enclosure design constraints. Ensure the through-hole termination method aligns with the PCB manufacturing capabilities. Cross-reference the UL94 V-0 rating with safety compliance standards required for the final assembly environment.

Headers, Male Pins Selection Notes

Select this component when a robust mechanical lock is required for high-vibration environments. The 1.27 mm pitch allows for dense circuit layouts while maintaining adequate spacing. Consider the 1kV rating if isolation requirements exceed standard low-voltage limits. The dual-row format maximizes I/O density within a compact footprint compared to single-row alternatives.
