M55-6012042R

Headers, Receptacles, Female Sockets Overview

The Harwin M55-6012042R is a board-to-board and mezzanine connector from the Archer Kontrol series. It features a 1.27 mm pitch with 20 positions arranged in two rows. The component is a female receptacle designed for vertical surface mount technology (SMT) termination. It utilizes gold-plated phosphor bronze contacts housed in liquid crystal polymer (LCP). Rated for 1.2 A current and 100 VAC voltage, it operates within a temperature range of -55°C to +125°C. The housing meets UL 94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Feature Summary

• Vertical SMT female receptacle design for compact board-to-board interconnects
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Liquid crystal polymer housing provides high thermal stability and UL 94 V-0 rating

Headers, Receptacles, Female Sockets Applications

• Board-to-board connections
• Mezzanine interconnects

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count and contact configuration against the official datasheet before procurement. Confirm that the vertical SMT orientation matches the PCB layout requirements. Ensure compatibility with mating male headers within the same Archer Kontrol series to guarantee proper mechanical engagement and electrical performance.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-density vertical connection is required. The 1.27 mm pitch supports moderate density applications. Verify that the 1.2 A current rating and 100 VAC voltage limit are sufficient for the target circuit. Consider the operating temperature range and LCP material properties for environmental resilience.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin Archer Kontrol M55-601 Series. It is specifically a 20-position female connector. It mates with corresponding male headers such as the M55-7012042R. The series is characterized by robust construction and precise alignment features suitable for automated assembly processes.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible mating parts include other connectors in the Archer Kontrol series with matching 1.27 mm pitch and 20 positions. Specific male counterparts like M55-7012042R should be verified for mechanical fit. Cross-series replacements require careful evaluation of pitch, height, and contact geometry.
