Choosing the Right Sensor in Five Steps
First of all, decide which sensor principle is suitable.This depends on the
material of the object to be detected.
If the object is metal, we recommend an inductive sensor.
If the object is plastic, paper or fluid (oil or water-based), granular or pow-
der, we recommend a capacitive sensor.
If the object contains a magnet, a magnetic field sensor is suitable.
You can find more background information on the physical effect of the
different types of proximity switches at the start of each relevant chapter.
Find the ideal sensor for your application in five steps:
•
Step 1: Housing design
•
Step 2: Operating distance
•
Step 3: Mounting conditions
•
Step 4: Electric data and connections
•
Step 5: General specification and special features
Step 1: Housing design
Rectangular sensors
This housing design introduced by Pepperl+Fuchs GmbH under the
brand names VariKont and VariKont M has the mounting hole arrange-
ment (housing designs IC30 and IC40) defined in European standard
EN 60947. This arrangement is the same as for mechanical position limit
switches. The VariKont comprises a stable basic housing (PBT or metal)
that is screwed to the mounting surface and contains the terminals. The
PBT add-on part is sealed against the basic housing with a neoprene
seal and contains the encoded connector. The add-on part contains the
switch amplifier. The sensor head can be adjusted in five directions, i.e.,
the active area can be aligned forwards, to the right, to the left, upwards,
or downwards.
The main difference between the VariKont and VariKont M types is their
dimensions, and this product can also be supplied with V1 connectors in
addition to terminals.
The
VariKont L
type does not have a terminal compartment, making it ex-
tremely compact so that it can be mounted using only a screwdriver. The
active area can be adjusted in increments of 15° within two planes and is
connected via cable or a V1 connector.

Area switches (FP)
These block-shaped sensors have a large front area (80 mm x 80 mm)
and therefore a long operating distance.They are comprised of two parts.
The lower part contains the terminal compartment and the top contains
the male pin and the sensor element along with the electronics, which are
vacuum encapsulated in casting resin. The top is always made from PBT
and the bottom can be made from either PBT or cast metal.They conform
with the mounting hole arrangement (housing design ID80) defined in
European standard EN 60947.
Cylindrical sensors
Their active area is on the front face in the axial direction. They are avail-
able in diameters from 3 mm (no thread) or 4 mm (with thread) to 30 mm
(
with thread) or 40 mm smooth (with terminal housing).
Surface mount proximity switches
These small proximity switches are mounted to the required surface.
Different versions are available with the active zone aligned upwards or
forwards.
The housing is usually made of PBT.
