What are the key features of M50-3200945?
- 1.27mm (0.05 inch) pitch dual-in-line horizontal throughboard socket with 18 gold-plated contacts
- Gold (Au) contact termination for superior conductivity and corrosion resistance in mated connections
- Compact body measuring 11.84mm long × 3.45mm wide for high-density PCB mounting
- RoHS compliant Pb-free construction suitable for global export and green electronics manufacturing
What is M50-3200945 used for?
The M50-3200945 is ideal for board-to-board interconnects in space-constrained embedded systems, daughter card assemblies, and modular electronics where 1.27mm pitch connectors provide higher density than standard 2.54mm pitch alternatives. Its horizontal throughboard orientation allows mating in a parallel plane, enabling stacked PCB configurations in industrial control modules, robotics, and test equipment. Gold-plated contacts ensure low contact resistance below 30mΩ and long insertion life exceeding 30 mating cycles in demanding environments.

Frequently Asked Questions
How many contacts does the M50-3200945 provide and what is the mating pitch?
The M50-3200945 features 9+9 dual-in-line contacts totaling 18 pins arranged on a 1.27mm (0.05 inch) pitch, which is half the spacing of standard 2.54mm DIP connectors. This tighter pitch allows 18 signal connections in a body length of only 11.84mm, supporting high pin-count interconnects in compact PCB layouts.
Why specify gold contact finish on the M50-3200945 for board-to-board connector applications?
Gold (Au) plating on the M50-3200945 contacts provides contact resistance below 30mΩ and resists oxidation over thousands of mating cycles, unlike tin or nickel finishes that form surface oxides increasing resistance over time. For low-voltage digital signal lines operating at 3.3V or 1.8V, where even 50mΩ contact resistance can degrade signal integrity, gold plating ensures consistent low-resistance connections throughout product lifetime.
In what orientation does the M50-3200945 mount and how does it differ from vertical socket alternatives?
The M50-3200945 mounts horizontally through the PCB, allowing the mating header to plug in parallel to the board surface rather than perpendicular. This horizontal throughboard orientation enables two PCBs to be connected edge-to-edge or at offsets within a chassis, saving at least 5mm in vertical stack height compared to vertical socket assemblies when used in sandwiched board arrangements.
