Need a reliable way to detect metal in your automation project?
This LJ18A3-8-Z/AY inductive proximity sensor is a 3-wire PNP normally closed unit.
It runs on DC 6 to 36 volts and has an 18mm threaded barrel.
The sensing distance is 8mm, perfect for CNC machines, 3D printers, or any industrial automation task.

It detects ferrous and non-ferrous metals without contact, so it's great for limit switches, positioning, or counting.
The sensor is made in China and is brand new.
It's also known as a metal detecting sensor for CNC or 3D printer applications.

The part number LJ18A3-8-Z/AY is the PNP NC version—make sure you get the right one for your setup.

If you need NPN or NO, check other models.
This one is specifically PNP normally closed.
Easy to wire: brown to positive, blue to negative, black to load.

If your project needs reliable metal sensing, this sensor is a cheap, solid choice.

18mm threads make mounting simple.
