M22-6540542R

Headers, Receptacles, Female Sockets Overview

The M22-6540542R is a 5-position female receptacle connector from the Harwin M22 series, featuring a 2mm pitch. Designed for surface mount technology (SMT), it utilizes a right-angle configuration to facilitate board-to-board connections. The contacts are gold-plated phosphor bronze, ensuring reliable electrical performance with a current rating of 2A and voltage rating of 500V. The housing is constructed from glass-filled liquid crystal polymer (LCP) rated UL94V-0, providing high thermal stability and mechanical durability.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount right-angle design optimizes vertical space on PCBs
• Gold-plated contacts enhance conductivity and corrosion resistance
• High-temperature LCP housing withstands reflow soldering processes

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections in compact electronic assemblies
• Industrial control systems requiring robust surface mount solutions
• General purpose electronics with height constraints

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix 'R' confirms the reel packaging format required for automated SMT assembly lines. Ensure compatibility with standard pick-and-place equipment specifications. Confirm that the gold plating thickness meets application requirements for contact resistance. Validate that the right-angle orientation aligns with the mechanical layout of the target PCB design before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, right-angle connection is necessary for dense PCB layouts. The 2mm pitch offers a balance between pin density and spacing reliability compared to finer pitches. The SMT mounting method eliminates through-hole drilling requirements, streamlining manufacturing. Consider the 2A current rating against total system load requirements to ensure adequate electrical capacity without overheating.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the M22 series, a family of industrial standard connectors known for their compact size and high reliability. The series supports various configurations including single and double rows with different pin counts. It is engineered for demanding environments where vibration resistance and thermal cycling performance are critical for long-term operational stability.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the M22 series include M22-6530542R (3-pin) or M22-6570542R (7-pin) if pin count adjustments are permissible. For generic replacements, verify identical 2mm pitch, SMT right-angle form factor, and compatible housing material properties to maintain mechanical and electrical integrity.
