This is a specific industrial cable for connecting sensors, actuators, and other automation devices. One end has a standard M12 A-coded 4-pin female connector (the round, screw-on type common in factories). The other end has the four individual wires stripped and ready for you to connect to terminals or solder – they're color-coded brown, white, blue, and black. The cable is 5 meters long (about 16.4 feet), is shielded to protect against electrical noise, and has a tough PVC jacket. It's built for harsh industrial environments and is compatible with networks like DeviceNet, CANopen, IO-Link, and PROFIBUS when used with the right devices. If you're replacing a broken cable, wiring up a new sensor to a controller, or extending a connection in a control panel, this is the kind of cable you need. Just make sure your device uses an M12 A-coded 4-pin female socket. A very niche but essential part for automation techs and engineers.
