M55-6021242R

Headers, Receptacles, Female Sockets Overview

The Harwin M55-6021242R is a 12-position female receptacle connector from the Archer Kontrol series, designed for board-to-board and mezzanine applications. It features a 1.27mm (0.050 inch) pitch with two rows of contacts. The connector utilizes phosphor bronze terminals with gold plating for reliable signal transmission and is housed in black liquid crystal polymer (LCP). Rated for 100VAC and 1.2A, it supports surface mount installation with a vertical orientation. The unit operates within a temperature range of -55°C to +125°C and meets UL94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to ensure correct contact configuration and packaging type. Confirm that the selected variant matches the required row count and terminal gender for the target assembly. Cross-reference the component specifications with the intended mechanical constraints and electrical ratings before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-density connection is required between stacked circuit boards. The 1.27mm pitch allows for significant pin counts in limited space while maintaining robust mechanical locking. Ensure the mating header aligns with the specified vertical orientation and surface mount footprint requirements for proper assembly.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Archer Kontrol family, which emphasizes secure latching mechanisms and automated pick-and-place compatibility. The series offers various configurations including male headers and female receptacles in both single and double-row arrangements. It is engineered for high-reliability environments requiring consistent performance under thermal stress.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify compatibility by matching the 1.27mm pitch, 12-position count, dual-row layout, and vertical SMT mounting style. Ensure any alternative component shares identical housing material properties and contact plating specifications.
