What are the key features of M22-7132542?
- 25-position SIL socket with 2.54mm pitch for direct mating with standard 0.1-inch pin headers
- Straight through-hole termination with 1.969-inch body length providing mechanical stability on PCB
- Tin (Sn) over Nickel (Ni) barrier contact finish for low contact resistance and corrosion protection
- RoHS-compliant lead-free construction suitable for environmentally regulated products
- 0.094-inch body breadth enabling dense connector placement on single-in-line board edges
What is M22-7132542 used for?
The M22-7132542 is used in prototyping boards, development kits, and modular embedded systems where a 25-way single-row receptacle must mate with standard 2.54mm pitch pin headers on a daughter card or ribbon cable assembly. Its straight through-hole body and tin-nickel contacts are appropriate for industrial control backplanes and test-fixture sockets that require repeated mating cycles with reliable electrical continuity. The 25-position count also suits parallel data bus interfaces and GPIO expansion boards where grouping all signals in a single SIL connector simplifies cable routing.

Frequently Asked Questions
What pitch and position count does the M22-7132542 provide, and which mating headers is it compatible with?
The M22-7132542 has 25 positions on a 2.54mm (0.1-inch) pitch, making it directly compatible with standard 2.54mm single-row pin headers used across virtually all development boards and prototype systems. The 25-position count accommodates a full 8-bit data bus plus address and control signals in a single connector block.
How does the tin-over-nickel contact finish on the M22-7132542 affect long-term connection reliability?
The nickel barrier layer prevents tin diffusion into the copper contact base, significantly reducing the growth of brittle intermetallic compounds that increase contact resistance over time. In applications with ambient temperatures up to 85°C and moderate humidity, tin-over-nickel contacts maintain contact resistance below 10mΩ through hundreds of mating cycles.
Is the M22-7132542 suitable for wave-solder assembly, and what board thickness does it require?
Yes, the straight through-hole termination is designed for wave-solder or selective-solder assembly processes. The pin length and body dimensions are sized for standard PCB thicknesses of 1.6mm, and Harwin specifies a recommended drill diameter for the plated through-holes in the M22-series datasheet, typically 0.9mm to 1.0mm, to ensure a reliable solder joint fillet.
How does the M22-7132542 compare to an IDC socket for connecting a 25-conductor flat cable?
Unlike an IDC socket that crimps onto a flat ribbon cable in a single press operation, the M22-7132542 is a PCB-mounted receptacle that mates with a discrete pin header; individual wires or a crimped housing must be assembled separately. The M22 offers lower contact resistance and better vibration resistance due to its through-hole soldered 25-pin body, making it preferable in high-reliability industrial environments where IDC reliability under vibration is a concern.
