RS PRO Inductive Barrel-Style Proximity Sensor, M18 x 1, 12 mm Detection, PNP Output, 10 → 30 V dc, IP68

Use this RS PRO inductive proximity sensor to detect delicate metal objects that could be damaged if touched. It's used to detect objects without physical contact and within a defined range, such as when sorting items on a factory production line.


The sensor's stainless steel body means it's tough and corrosion-resistant, so it can withstand installation in demanding industrial environments. Its IP68 (Ingress Protection) rating makes it completely dust-tight and water-resistant. It also offers high thermal resistance for use in hot settings. This versatile sensor can detect both ferrous and non-ferrous metals and is suitable for use in food processing applications.

These Proximity Sensors are commonly used for the following magnetic output applications:

• Forklift Truck


• Food industry


• Beverage industry


• Robotics


• Packing and materials handling


• For monitoring components positions within hydraulic machines

How Inductive Sensors work?

Inductive sensors contain a coil and an oscillator that create an electromagnetic field close to the sensing surface. When metal enters this field, a change occurs in the oscillating amplitude. This, in turn, changes the sensor output, showing the user and/or corresponding equipment that metal has been sensed.

The operating distance varies between sensors and can be affected by the target, the shape of what is being detected and what environment or material you are using the sensor in. These are all things to bear in mind when choosing the right sensor for your application.
