Frequently Asked Questions
How many positions does the M50-3901042 have and what is its pitch?
The M50-3901042 is a 10-position receptacle with 1.27 mm (0.050 inch) pitch. Its body measures 0.5 inch in length, 0.134 inch in breadth, and 0.188 inch in depth, making it suitable for compact PCB layouts with tight connector spacing.
In which industrial or embedded computing applications is the M50-3901042 typically deployed?
This 10-pin, 1.27 mm pitch receptacle is widely used in industrial control modules, single-board computers, and test equipment interconnects. The RoHS-compliant tin-over-nickel contact finish ensures it meets environmental regulations while providing reliable signal continuity over many mating cycles in demanding environments.
What contact finish does the M50-3901042 use and why does it matter for long-term reliability?
The M50-3901042 uses a tin (Sn) finish over a nickel (Ni) barrier on termination contacts. Nickel acts as a diffusion barrier preventing tin migration into the base metal, maintaining low contact resistance across the connector's service life and ensuring stable performance even after repeated 1.27 mm pitch mating cycles.
