The OMRON XW4M/XW4N series offers 3.5mm-pitch push-in terminal block PCB connectors designed to significantly enhance the efficiency of connector insertion/removal and cable wiring. Featuring a unique engagement structure for easy handling and high contact reliability, these connectors streamline inspection, assembly, and maintenance processes. They are compatible with through-hole-reflow mounting and include standard pin numbers printed on the socket's top surface for clear identification. The "hands-free" mechanism allows for efficient wiring by keeping the screwdriver inserted. Optional accessories like coding keys, short bars, and release tools are available to prevent erroneous insertion and facilitate specific functionalities.
