Ultrasonic proximity switch with

Ultrasonic Sensors
Product Description
The sks sensor offers a non-contact
measurement of the distance to an
object which must be positioned
within the sensor’s detection zone.
The switched output is set in depen-
dence of the adjusted detect dis-
tance.
Via the push-button, the detect dis-
tance and operating mode can be
adjusted (teach-in). Two LEDs indi-
cate operation and the state of the
switched output.
The output function is changeable
from NOC to NCC. Safety Notes
■ Read the operating instructions
prior to start-up.
■ Connection, installation and
adjustment works may only be
carried out by expert personnel.
■ No safety component in
accordance with the EU Machine
Directive
Proper use
sks ultrasonic sensors are used for
non-contact detection of objects.
Installation
■ Mount the sensor at the installa-
tion site.
Maximum torque: 0,5 Nm
■ Connect a connection cable to the
M8 device plug.

Start-Up
■ Connect the power supply.
■ Carry out the adjustment in
accordance with the diagram.
Factory Setting
■ Operation with one detect point
■ Switched output on NOC
■ Detect points at operating range
Operating modes
Three operating modes are available
for the switched output:
■ Operation with one detect point
The switched output is set if the ob-
ject falls below the set detect point.
■ Window mode
The switched output is set if the ob-
ject is within the set window mar-
gins.
■ Two-way reflective barrier
The switched output is set if the ob-
ject is between sensor and reflector.
Checking operation mode
■ In normal mode shortly press the
push-button.
The green LED stops shining for one
second, then it will show the current
operation mode:
1 x flashing = operation with one
switching point
2 x flashing = window mode
3 x flashing = reflective barrier
After a break of 3 s the green LED
shows the output function:
1 x flashing = NOC
2 x flashing = NCC
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface
Notes
■ sks-15/CD and sks-15/CE sensors
have internal temperature com-
pensation. Because the sensors
heat up on their own, the tempe-
rature compensation reaches its
optimum working point after ap-
proximatly 30 minutes of operati-
on.
The sensors sks-15/D and sks-15/E
have no temperature compensati-
on.
■ The sks sensor has a blind zone,
within which distance measure-
ments are not possible.
■ In the normal operating mode, an il-
luminated yellow LED signals the
switched output is switched
through.
■ If the object to be sensed moves
into the detection area from the
side, the switching distance should
be set 8-10 % further than the de-
sired switch point to obtain a reli-
able object detection.
If the object moves towards the
sensor (e.g. level control) the de-
tect point can be taught to the ac-
tual distance at which the sensor
has to switch the output.
