Ultrasonic proximity switch with
one switched output

Product Description

The zws 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 depen­dence of the adjusted detect dis­tance.
Via the push-button, the detect dis­tance and operating mode can be
adjusted (teach-in). Two LEDs indi­cate operation and the state of the
switched output.

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

zws ultrasonic sensors are used for
non-contact detection of objects.

Installation

 Mount the sensor at the installa-

tion site with the aid of the
enclosed mounting plate.
Maximum torque: 0,5 Nm

Fig. 1: Attachment with mounting plate

 Connect a connection cable to the

M8 device plug.

 Avoid mechanical load on the con-

nector.

Fig. 2: Pin assignment with view onto sensor

plug and colour coding of the
microsonic connection cable

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 ob­ject falls below the set detect point.

 Window mode

The switched output is set if the ob­ject is within the set window mar­gins.

 Two-way reflective barrier

The switched output is set if the ob­ject is between sensor and reflector.

Synchronization

You can synchronize as many sensors
as you like.

 Apply a square-wave signal to the

sync-input with pulse width ti and
repetition rate tp (Fig.3 and
technical data).

A high level on the sync-input will
deactivate the sensor.

Fig.3: External synchronization signal

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

operating 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 maintenance­free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface

Notes

 The zws sensor has a blind zone,

within which distance measure­ments are not possible.

 In the normal operating mode, an il-

luminated yellow LED signals the
switched output is switched
through.

 The standard sensor has no tempe-

rature compensation.

 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 de­sired switch point to obtain a reli­able object detection.
If the object moves towards the
sensor (e.g. level control) the detect
point can be taught to the actual
distance at which the sensor has to
switch the output.

Detection zones

for different objects:

The dark grey areas are determined

with a thin round bar (10 mm dia.)

and indicate the typical operating range
of a sensor. In order to obtain the light grey
areas, a plate (100 x 100 mm) is introduced

into the beam spread from the side.

In doing so, the optimum angle between

plate and sensor is always employed.

This therefore indicates the maximum

detection zone of the sensor.

It is not possible to evaluate ultrasonic

reflections outside this area.

In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.

 If the push-button is not pressed

for 10 minutes during the teach-in
setting, the settings made hitherto
