M55-3101242R

Headers, Male Pins Overview

The Harwin M55-3101242R is a board-to-board connector from the Archer Kontrol series, featuring 12 positions with a 1.27 mm pitch. It utilizes a single row of male pins designed for surface mount technology (SMT) in a right-angle configuration. The contacts are gold-plated phosphor bronze, supporting a current rating of 1.2 A. The housing is constructed from liquid crystal polymer (LCP) with UL 94 V-0 flammability ratings. Operating temperatures range from -55°C to +125°C, and it includes mounting pegs for secure installation.

Headers, Male Pins Feature Summary

• Archer Kontrol series design ensures precise alignment and reliable mating through controlled contact geometry.
• Right-angle surface mount termination facilitates compact vertical interconnections on printed circuit boards.
• Gold-plated phosphor bronze contacts provide durable conductivity and resistance to corrosion.

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Compact electronic module assembly
• Vertical stacking of circuit boards

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, pitch, and termination style. Ensure compatibility with automated pick-and-place equipment due to the SMT right-angle form factor. Cross-reference the mounting peg requirements with the target PCB layout to guarantee mechanical stability during assembly and operation.

Headers, Male Pins Selection Notes

Select this component when a single-row, right-angle board-to-board connection is required with a 1.27 mm pitch. The 12-position count suits moderate density applications. Verify that the operating temperature range of -55°C to +125°C meets environmental specifications. Confirm that the surface mount process aligns with the manufacturing capabilities of the production line.

Headers, Male Pins Part Context

This part belongs to the Harwin M55 series, known as Archer Kontrol. This family focuses on high-reliability board-to-board connectors. The series offers various configurations including different row counts and pitches. The M55-3101242R specifically addresses needs for right-angle, single-row interconnects within this robust product line.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M55-7101242R, which shares the 12-position count and 1.27 mm pitch but differs in orientation by being a straight rather than right-angle connector. Other M55 variants may offer different row counts or contact materials, requiring careful verification of mechanical and electrical parameters before substitution.
