What Makes These Sensors So Good?

  • Sensing Range: Pepperl+Fuchs Inductive Proximity Sensors come in various sensing ranges, from a few millimetres to several centimetres. This makes it easy to simply select the right sensor for your specific application!
  • Output Types: These sensors typically offer two types of outputs: NPN (normally open) and PNP (normally closed). The choice of output type is up to you, your applications needs and your current control system.
  • Housing Materials: Pepperl+Fuchs offer a great choice of housing materials. Stainless steel, brass, plastic - it's whatever suits the environmental conditions of your application!
  • Mounting Options: There's a variety of mounting options from Pepperl+Fuchs, most commonly flush mount vs non-flush mount, to accommodate different installation needs.
  • Environmental Protection: Many of these sensors are designed to withstand harsh industrial environments and are rated for protection against key factors like dust, moisture, and vibration.
  • Temperature Range: The sensors are designed to operate within a wide temperature range, allowing them to function reliably in both hot and cold climates.
  • Customisation: Pepperl+Fuchs even offer customisation options on their inductive proximity sensors, so if your application isn't standard, you can still get what you need!
  • Integration: These clever sensors can be easily integrated into your automated systems and control processes, making them an essential component in industrial automation and robotics.

How Do They Work?

Inductive Proximity Sensors work like this: Creating a high-frequency electromagnetic field around them, like invisible radio waves, they can detect when a metal object gets close to the sensor, and it changes the field. The sensor notices this change and then sends an output signal to show that something metal is nearby. If there shouldn't be metal roaming around your production, you'll be alerted of this intrusion, but if you should have metal detected consistently and the frequency changes, you'll also know something is missing! Even without customising actual components of the sensor you order, the output can be customised to your application needs.

The Sensor Types

Metal Barrel vs Varikont - What's the difference and what's best? Ultimately, both types of sensor do the same job, but they have different aspects, features and benefits along the way.


The most obvious differentiation being their size and housing. The clue is in the name with the Metal Barrel - a cylindrical metal housing, often made with stainless steel to withstand tougher environments. Varikont sensors however are more compact, and usually have a smaller footprint compared to the Metal Barrel version. Their housing is a generally plastic or hybrid material, focussing on being lightweight and flexible.


In both cases, Pepperl+Fuchs Inductive Proximity Sensors offer a range of sensing distances to meet differing needs. While Varikont sensors are designed with flexibility in mind, their sensing distance offering is limited compared to some of the Metal Barrel versions that can sense a further distance.


Mainly due to the housing material differences, Metal Barrel and Varikont inductive proximity sensors are better suited to different kinds of applications. Commonly used in industries like manufacturing, mining, and automotive, metal barrel sensors are highly robust, able to withstand harsh environments. On the other hand, Varikont sensors are less robust, but can still be utilised in large applications due to their versatility. They're often utilised in conveyor systems, packaging machinery, and other applications where space and flexibility are important.
