M55-3100842R

Headers, Male Pins Overview

The M55-3100842R is an Archer Kontrol series header connector manufactured by Harwin. It features a 1.27 mm pitch and comprises 8 positions arranged in a single row. Designed for surface mount technology, the component utilizes right-angle termination to facilitate horizontal PCB mounting. The contacts are constructed from phosphor bronze with gold plating to ensure reliable signal transmission. The housing is made of black liquid crystal polymer (LCP), rated UL 94 V-0 for flammability. Electrical ratings include 100VAC voltage and 1.2A current per contact.

Headers, Male Pins Feature Summary

• Surface mount right-angle design for compact horizontal board integration
• Gold-plated phosphor bronze contacts for durable conductivity
• High-temperature resistant LCP insulation material

Headers, Male Pins Applications

• Handheld electronic equipment
• General purpose industrial interconnects
• Compact consumer electronics assemblies

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration when sourcing. Confirm that the 1.27mm pitch and single-row layout match the target PCB footprint requirements. Ensure compatibility with standard SMT reflow profiles suitable for LCP materials. Cross-reference the UL 94 V-0 rating against specific environmental safety standards required for the end application.

Headers, Male Pins Selection Notes

Select this model for applications requiring low-profile horizontal connections with robust solder joint integrity. The 1.27mm pitch offers a balance between density and spacing compared to finer pitches. Consider the right-angle orientation for space-constrained designs where vertical headers are impractical. Validate that the 1.2A current rating meets the circuit load requirements without excessive heating.

Headers, Male Pins Part Context

This component belongs to the Harwin M55 series, known as Archer Kontrol. This series focuses on industrial-grade connectors with high reliability. The M55 line includes various configurations such as IDC and board-to-board options. The M55-3100842R specifically addresses the need for simple, reliable header connections in dense electronic layouts.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same family include M55-6016842R for vertical female variants or M55-7156842R for dual-row configurations. Verify pin count and pitch compatibility before substitution. Alternative manufacturers may offer similar 1.27mm pitch headers, but mechanical dimensions and electrical ratings must be strictly matched.
