Product Description
The zws sensor is designed to measure the distance to an object without making contact. The object must be positioned within the sensor’s detection zone. Depending on the set window limits, the sensor outputs a distance-proportional analogue signal. The window limits and its characteristic can be adjusted using the push-button (Teachin). The sensor also features two LEDs to indicate operation and the state of the analogue output.
Safety Notes
- Read the operating instructions prior to start-up.
- Connection, installation, and adjustment works must only be carried out by expert personnel.
- Use for intended purpose only.
- No safety component in accordance with the EU Machine Directive.
Factory Setting
The sensor has a rising analogue characteristic curve between the blind zone and the operating range.
Diagram 1: Set Sensor Parameters via Teach-in Procedure
To set the sensor parameters, follow the steps below:
- Set analogue output.
- Set window limits.
- Set rising/falling output characteristic curve.
Place the object at position 1 and press the push-button for about 3 seconds until both LEDs flash alternately. Place the object at position 2 and press the push-button for about 1 second. Press the push-button for about 13 seconds until both LEDs flash alternately. The green LED flashes, and the yellow LED indicates the rising/falling characteristic curve. To change the output characteristic, press the push-button for about 1 second.

coding of the microsonic connection cable.
Fig. 3: External Synchronisation Signal
The sensor features a sync-input with pulse width ti and repetition rate tp
(Fig. 3 and technical data). A high level on the sync-input will disable the
sensor.
Further Settings
- Enable/disable Teach-in push-button.
- Reset to factory setting.
To enable/disable Teach-in, switch off operating voltage, press and hold the push-button, switch on operating voltage, and keep the push-button pressed for about 3 seconds until both LEDs flash simultaneously. The green LED indicates the push-button is enabled, and the yellow LED indicates it is disabled. To reset to factory setting, switch off operating voltage, press and hold the push-button, switch on operating voltage, and keep the push-button pressed for about 13 seconds until both LEDs stop flashing.
Maintenance
The microsonic sensors are maintenance-free. In case of excess caked-on dirt, we recommend cleaning the white sensor surface.
Notes
- Every time the power supply is switched on, the sensor detects its actual operating temperature and transmits it to the internal temperature compensation. This results in a slight correction of the analogue output value after 45 seconds.
- If the sensor was switched off for at least 30 minutes and after power on an object is placed in the middle of the adjusted analogue window for 30 minutes (the analogue output value is in the range of 11 to 13 mA or 4.4 to 5.6 V), a new adjustment of the internal temperature compensation to the actual mounting conditions takes place.

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. In dependence of
the set window limits, a distance-proportional analogue signal is output.
Via the push-button, the window limits of the analogue output and its
characteristic can be adjusted (Teach-in). Two LEDs indicate operation and the
state of the analogue 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
Use for intended purpose only zws ultrasonic sensors are used for non-contact detection of objects.
Installation
- Mount the sensor at the installation site with the aid of the enclosed mounting plate (see Fig. 1). Maxi-mum torque of attachment screw: 0,5 Nm
- Connect a connection cable to the M8 device plug (see Fig. 2).
- Avoid mechanical load on the connector.
Start-Up
- Connect the power supply.
- Carry out the adjustment in accordance with Diagram 1.
Factory Setting
- Rising analogue characteristic curve between the blind zone and the operating range

Synchronization
You can synchronize as many sensors as you like.
- Apply a square-wave signal to the sync-input with pulse widths and repetition rate tp (Fig. 3 and technical data).
A high level on the sync-input will disable the sensor.

Checking operation mode
- In normal operating mode shortly press the push-button. The green LED stops shining for one second, then it will show the current characteristic of the analogue out-put:
- 1x flashing = rising
- 2x flashing = falling
Maintenance
microsonic sensors are maintenance-free. In case of excess caked-on dirt we
recommend cleaning the white sensor surface.
Notes
- Every time the power supply is switched on, the sensor detects its actual operating temperature and transmits it to the internal temperature compensation. This results in a slight correction of the analogue output value after 45 seconds.
- If the sensor was switched off for at least 30 minutes and after power on an object is placed in the middle of the adjusted analogue window for 30 minutes (the analogue out-put value is in the range of 11 to 13 mA or 4.4 to 5.6 V) a new adjustment of the internal temperature compensation to the actual mounting conditions takes place.
- The zws sensor has a blind zone, within which distance measurements are not possible.
- In the normal operating mode, an illuminated yellow LED signals the object is within the adjusted window limits.
- If the push-button is not pressed for 30 seconds during the teach-in set-ting, the settings made hitherto are deleted.
- The sensor can be reset to its factory setting (see »Further settings«, Diagram 1).
