2.1 Use for Intended Purpose
This wenglor product is intended for use in accordance with the following functional principle
Inductive Sensors with Standard Switching Distance
Inductive Sensors with Increased Switching Distance
Inductive sensors are used to detect the position of metallic objects. A coil is located underneath the sensing
face of inductive sensors which generates a magnetic field. Approaching metal objects (e.g. steel, aluminum
or brass) generate eddy currents within this magnetic field which are measured by the sensor. When the
approaching metal object reaches the selected switching distance, the output is switched.

Installation dimension Description
A Minimum distance from sensor to damping material (e.g. steel).
B Minimum distance between two inductive sensors.
This clearance applies to installation in air. If the sensors are installed within an
attenuating material (e.g. steel), this distance is reduced. Testing in the applica-
tion is required in order to determine the exact distance.
C Minimum distance from the sensing face of the inductive sensor to the damping
material (e.g. steel).
Distance C does not make reference to the object to be detected, but rather
to the background. The object to be detected is detected within the switching
distance.
D Minimum dimension by which the sensor (sensing face) must protrude from the
damping material (e.g. steel).
8 × Sn Installation opposite each other Two identical sensors must be mounted at this
minimum distance.

5.3.2 Installation instructions for sensors with weproTec
weproTec is the abbreviation for wenglor proximity switch technology, an innovative, patented wenglor tech-
nology for inductive sensors.

or opposite one another (1.5 ×Sn). No reciprocal influence occurs among the sensors within the specified
zones.
The installation instructions in accordance with the standard (section “5.3.1 Installation Instructions in Accor-
dance with Standard” on page 11) are also valid.
weproTec has the following sensors:
I08xxxx, I12xxxx, I18xxxx, I30xxxx, I1AHxxx, I1BHxxx, I1CHxxx, I1DHxxx, I1QHxxx

5.4 Switching distance
• The switching distance described in the data sheet is the nominal switching distance Sn according to the
standard.
• The switching distance refers to a standard measuring plate (material: steel, thickness: 1 mm,
side lengths: 3× Sn or outside diameter sensor).
• The switching distance according to the standard is further differentiated into:
– Effective switching distance Sr
– Useable switching distance Su
– Working distance Sa
Standard measuring plate
Useable switching distance S u max
Effective switching distance S r max
Nominal switching distance S n
Effective switching distance S r min
Useable switching distance S u min
Working distance S a Sensing face
(safely switched on)
NOTE!
• If the objects in the application are smaller than the standard measuring plate, the
switching distance is also reduced.
• The correction factor of the sensor for certain materials also influences the switching dis-
tance and must be observed.
• The sensor should be mounted at a working distance Sa or less to the object.

15
Inductive Sensors
5.5 Electrical Connection
• Wire the sensor according to the connection diagram (for the connection diagram see packaging or prod-
uct detail page at www.wenglor.com)
• Connect the sensor to 10...30 V DC
DANGER!
Risk of personal injury or property damage due to electric current.
Live parts may cause personal injury or damage to equipment.

Object distance < 0.71 mm
Error Short circuit Check the electrical wiring and elimi-
nate the short circuit
Mechanical damage to the coil Replace the sensor
Required Action in Case of Fault:
