M50-3652042R

Headers, Male Pins Overview

The M50-3652042R is a 40-position, 2-row surface mount pin header from the Harwin Archer M50 series. It features a 1.27mm (0.050 inch) mating pitch and vertical orientation. The connector utilizes gold-plated brass contacts with a liquid-crystal polymer insulator housing rated UL94 V-0. It supports a maximum current of 1.75A per contact and operates within a temperature range of -55°C to +105°C. The design includes an ejector mechanism for secure board-to-board or wire-to-board connections.

Headers, Male Pins Feature Summary

• Integrated ejector mechanism ensures secure retention during mating cycles
• Vertical surface mount termination facilitates automated pick-and-place assembly
• Gold-plated brass contacts provide reliable conductivity in high-density layouts

Headers, Male Pins Applications

• High-density board-to-board interconnects
• Wire-to-board connections requiring vertical profile
• Automotive electronic control units
• Industrial instrumentation modules

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required ejector feature and SMT orientation. Confirm insulation material compatibility with reflow soldering profiles. Ensure mating connectors support the 1.27mm pitch and square contact shape. Check RoHS compliance status against project requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when vertical space is constrained but high retention force is needed due to the ejector design. Consider the 1.75A current rating for power distribution lines. Verify that the PCB footprint accommodates the specific SMT pad layout. Compare against standard headers if mechanical retention via screws is preferred over the integrated ejector system.

Headers, Male Pins Part Context

This part belongs to the Archer M50 family, known for compact rectangular connectors. The M50 series offers various row counts and termination styles. The M50-3652042R specifically addresses applications needing robust vertical SMT headers with positive locking features for vibration-prone environments.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27mm pitch, 40-position count, 2-row configuration, and SMT vertical mounting style. Verify identical ejector functionality and UL94 V-0 insulation rating. Cross-reference contact plating thickness and current ratings to ensure electrical equivalence.
