What are the key features of M22-7140542?
- RoHS-compliant lead-free construction with tin (Sn) over nickel (Ni) barrier contact finish for corrosion resistance
- Compact socket body measuring 0.394 x 0.157 x 0.173 inch enabling high-density board connector placement
- Robust board connector design rated for repeated mating cycles in harsh industrial and defence environments
- Nickel barrier underplate prevents tin whisker migration, extending connector reliability over long service life
What is M22-7140542 used for?
The M22-7140542 is used in compact embedded computing boards, industrial sensor modules, and rugged military electronics where PCB real estate is limited and RoHS compliance is mandatory. Its socket-style board connector design simplifies field replacement of mating plug assemblies without desoldering the PCB-mounted component. Defence and aerospace system integrators also select this connector for its tin-nickel contact durability across wide temperature swings.

Frequently Asked Questions
What are the body dimensions of the M22-7140542 and how do they influence PCB layout spacing?
The M22-7140542 body measures 0.394 inch long, 0.157 inch wide, and 0.173 inch deep. These compact dimensions allow center-to-center pitch as tight as 0.2 inch between adjacent connectors, enabling high-density arrangements on boards where every 5 mm of PCB space matters in embedded computing or sensor hub designs.
How does the tin-over-nickel contact finish in the M22-7140542 affect long-term connection reliability?
The tin (Sn) contact finish with a nickel (Ni) diffusion barrier inhibits copper migration and limits tin whisker growth, maintaining contact resistance below 30 mΩ over thousands of mating cycles. This makes the M22-7140542 suitable for industrial equipment expected to operate reliably for 10 or more years in environments with temperature cycling between -40°C and +85°C.
For which industries is the M22-7140542's RoHS compliance most critical during procurement?
RoHS compliance is mandatory for products sold in the European Union, so industrial automation OEMs, consumer electronics brands, and medical device manufacturers all require parts like M22-7140542 that carry verified lead-free certification. Defence contractors exporting to NATO nations also increasingly demand RoHS-compliant connectors to satisfy environmental directives across 27 member states.
Can the M22-7140542 be used in high-vibration defence or aerospace applications?
Yes. Harwin's M22 series connectors are engineered for vibration resistance, with the socket shell locking mechanism capable of withstanding 20 G shock and 10 G sinusoidal vibration per MIL-STD-202 Method 213. The 0.394 inch body length provides sufficient retention force for airborne and vehicle-mounted electronics subject to continuous mechanical stress.
