M55-7104042R

Headers, Male Pins Overview

The M55-7104042R is a surface mount right-angle male header from the Harwin Archer Kontrol series. It features a 1.27mm pitch with 40 positions arranged in two rows. The connector utilizes phosphor bronze contacts with gold plating and LCP insulation rated UL94 V-0. Rated for 1.2A and 100VAC, it operates between -55°C and +125°C. Key specifications include a mating contact length of 4.00mm, an insulation height of 6.76mm, and a stacking height of 8.25mm.

Headers, Male Pins Feature Summary

• Right-angle surface mount design for compact board-to-board interconnects
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission
• High-temperature LCP insulation supporting demanding thermal environments

Headers, Male Pins Applications

• Automotive electronic systems
• Industrial control modules
• General purpose circuit boards

Headers, Male Pins Procurement Notes

Verify the specific suffix '42R' against official Harwin documentation to confirm right-angle orientation and reel packaging format. Ensure compatibility with mating female connectors within the same 1.27mm pitch family. Cross-reference the 40-position count and dual-row configuration with schematic requirements before procurement.

Headers, Male Pins Selection Notes

Select this component when a right-angle profile is required for space-constrained vertical stacking. The 1.27mm pitch suits high-density applications. Confirm that the 8.25mm stacking height fits the mechanical envelope. Validate that the 1.2A current rating meets the circuit load requirements.

Headers, Male Pins Part Context

This part belongs to the Archer Kontrol M55-700 series, designed for robust board-to-board connections. The series offers flexible configurations including horizontal, vertical, and right-angle options. It supports data rates up to 3Gbit/s and provides secure pin-locking mechanisms for vibration resistance.

Headers, Male Pins Replacement Considerations

Compatible mates include M55-6104042R (female counterpart). Verify exact dimensional tolerances and locking mechanism alignment when substituting with other 1.27mm pitch headers.
