M55-7025042R

Headers, Male Pins Overview

The Harwin M55-7025042R is a surface-mount board-to-board connector from the Archer Kontrol series. It features a 1.27 mm pitch, 2 rows, and 50 positions. The male contacts are gold-plated phosphor bronze housed in liquid crystal polymer (LCP). Designed for vertical mounting with solder retention, it supports pick-and-place assembly. The operating temperature range is -55°C to 125°C, and the housing meets UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Vertical male header design with integrated solder retention for secure surface-mount processing
• Archer Kontrol guide system ensures precise alignment during board-to-board mating
• Gold-plated phosphor bronze contacts provide reliable electrical performance in LCP housings

Headers, Male Pins Applications

• High-density board-to-board interconnects in telecommunications equipment
• Signal transmission in industrial control systems requiring robust surface-mount headers
• Automotive electronics modules utilizing controlled impedance connectors

Headers, Male Pins Procurement Notes

Verify that the specific part number M55-7025042R matches the required 50-position configuration and 1.27 mm pitch before procurement. Confirm that the supplier provides original manufacturer documentation to ensure authenticity. Check RoHS compliance status and verify that the packaging type aligns with automated assembly requirements. Ensure storage conditions maintain the integrity of the gold-plated contacts and LCP material properties.

Headers, Male Pins Selection Notes

Select this component when a vertical, surface-mount board-to-board connection is required with high pin density. The 1.27 mm pitch allows for compact layouts compared to larger spacing options. The Archer Kontrol feature is essential for applications demanding precise alignment without external guides. Consider the -55°C to 125°C operating range for environments with significant thermal variations. Verify that the male contact style matches the corresponding socket or female header in the assembly.

Headers, Male Pins Part Context
