Pepperl+Fuchs Inductive Proximity Sensors

Due to the low values of current and voltage allows installation of products in hazardous areas. Sensors with the output of NAMUR type are intended for connecting to the external switching amplifier (barrier), transformative change in the output current in a two-level output signal (transistor or relay). The Pepperl Fuchs Company offers a wide spectrum of switching amplifiers for hazardous and normal applications.

Inductive sensors in rectangular housings.
The housing of these sensors, presented by Pepperl+Fuchs under the brand name Varikont and Varikont M, have mounting holes, according to the European standard of EN 60947. The location of these holes is similar to the layout of the holes of the mechanical position sensors. The head of sensor can be orientated in five different directions, that a sensible surface can be  can be shifted up, down, left, right or forward.
Sensors in the Varikont L housing are compact and can be easily installed with a screwdriver; position of their sensible surface is regulated within a 15-degree deflection in two planes.

The main characteristics of standard inductive proximity sensors are:
- threaded or smooth stainless steel;
- short circuit protection;
- led status indicators;
-connection types: connectors M12, M8 or terminal connection;
-protection against reverse polarity and
- PUR,  PVC or silicon cable types;
- 2...4-wire outputs DC current, AC current,   AS-interface and NAMUR.

Besides standard execution there are models with special characteristic such as high protection class (IP68/IP69), analog output 4-20 mA, model with sensitive stainless steel surface, resistant to welding design coated with PTFE, sensors with safety function, extended operating temperature (40 °C … +250°C).
