Frequently Asked Questions
What contact material and termination finish does the M22-6551042R connector use?
The M22-6551042R uses phosphor bronze female contacts with a tin (Sn) termination finish over a nickel (Ni) barrier, providing corrosion resistance and low contact resistance across the connector body measuring 0.799 x 0.157 inch. This material combination ensures reliable electrical performance in industrial and aerospace board connector applications.
Which high-reliability applications is the Harwin M22-6551042R connector designed for?
The M22-6551042R is part of Harwin's M22 rugged connector series, designed for aerospace, defense, and industrial applications subject to high vibration, mechanical shock, and thermal cycling. Its phosphor bronze contacts with tin-nickel termination deliver consistent mating force retention over thousands of insertion cycles, making it suitable for avionics, ground vehicles, and industrial robotics requiring 0.157 inch pitch board interconnects.
Is the M22-6551042R RoHS compliant, and what does its Pb-free status mean for supply chain sourcing?
Yes, the M22-6551042R is Pb-free and RoHS compliant, meaning it meets the European Union Restriction of Hazardous Substances directive that prohibits lead in electronic assemblies. For supply chain sourcing, this ensures the connector can be used in consumer, industrial, and medical products shipped to EU and other regulated markets without requiring hazardous material exemptions or special handling during PCB soldering processes.
How does the body size of M22-6551042R compare to standard 0.1 inch pitch connectors for board layout planning?
The M22-6551042R body measures 0.799 inches long by 0.157 inches wide by 0.49 inches deep, which is more compact than many standard 0.1 inch pitch dual-row connectors while maintaining robust mating force. This size allows PCB designers to route signal traces around the connector footprint in dense layouts typical of industrial control boards and embedded computing modules.
