M55-3000442R

Headers, Male Pins Overview

The Harwin M55-3000442R is a 4-position single-in-line (SIL) male header from the Archer Kontrol series. It features a 1.27 mm pitch and is designed for vertical surface-mount technology (SMT) termination. The connector supports a current rating of 1.2 A per contact and withstands voltages up to 100 VAC. Operating temperatures range from -55°C to +125°C, with contacts gold-plated over phosphor bronze.

Headers, Male Pins Feature Summary

• Vertical surface-mount design for efficient PCB integration
• Single row configuration for compact board-to-board connections
• Gold-plated phosphor bronze contacts for reliable conductivity

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronics
• Wire harness connections via headers
• High-density mezzanine applications

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing. Confirm that the 4-position count matches the SIL requirement. Ensure the vertical orientation aligns with the target PCB layout constraints before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component for applications requiring a low-profile, single-row connection. The 1.27 mm pitch suits high-density designs. Verify that the 1.2 A current rating meets the circuit requirements and that the SMT process is compatible with the specified operating temperature range.
