Mounting

Mounting multiple ultrasonic sensors

5.3.1

Minimum mounting distances

If you would like to operate multiple ultrasonic sensors and the mount-

ing distance is lower than the value specified in Table 3 (page 16), we

recommend using synchronization or multiplex mode. Synchronization or

multiplex mode avoids mutual interference between the sensors.

→

For synchronization mode, see Page 16, Chapter 5.3.2.

→

For multiplex mode, see Page 17, Chapter 5.3.3.

Synchronization mode

NOTE!!

The synchronization mode is not available in IO-Link

mode.

Description of synchronization mode

Synchronization mode begins automatically as soon as the sensors are

interconnected via PIN 5 (MF).
The sensors measure simultaneously in synchronization mode.

This operating mode prevents unwanted mutual interference since

measurements from different times are not incorrectly compared with one

another. The sensors can therefore be mounted without taking into account

mounting distances.

The acoustic pulses of a sensor deflected by an object can still be analyzed

by neighboring sensors. This makes it possible to implement more reliable

and simultaneous monitoring of large areas with synchronization mode, but

without position detection of the recorded objects.
The detection zone is enlarged to a size which covers all synchronized

sensors. A maximum of 20 sensors of type UM18-2 Pro can be connected,

and they can also be combined with synchronizable SICK ultrasonic

sensors from other product families.
The response time of the overall system is determined by the sensor with

the highest response time.
