Need a reliable sensor to detect when metal parts are nearby? This PR12-4AC is a workhorse. It's an AC-powered inductive proximity sensor with a 4mm detection range. The 'Normally Closed (NC)' wiring means the circuit is complete until a metal object comes within 4mm, then it opens.
Built with a brass shell and an ABS sensing face, it's tough for industrial environments. It runs on common AC voltage (110-220V, 50/60Hz) and can handle temperatures from -30°C to +65°C. Perfect for automation, CNC machines, conveyor systems, or any setup where you need to sense the position of metal objects without physical contact.
Comes as a single sensor. Wiring is simple with just two wires. Mounts easily with its threaded barrel. A durable, no-frills sensor that gets the job done in workshops, factories, or DIY projects.
