Long Range Ultrasonic Proximity Sensor Internal Synchronisation 5 Sensors
 
Description
 
Ultrasonic sensors present the ideal solution for non-contact position and distance measurement in all industrial areas where environmental conditions such as dust, smoke or steam may affect the sensors. Objects consisting of a variety of materials can be detected to within millimeters regardless of color or shape.
 
Technical data

External synchronization

The sensor can be synchronised by the external application of a square wave voltage. A synchronisation pulse at the
synchronisation
input starts a measuring cycle. The pulse must have a duration greater than 100 μs. The measuring cycle starts with
the falling edge of a synchronisation pulse. A low level > 1 s or an open synchronisation input will result in the normal
operation
of the sensor. A high level at the synchronisation input disables the sensor. Two operating modes are available:
1. Multiple sensors can be controlled by the same synchronisation signal. The sensors are synchronised.
2. The synchronisation pulses are sent cyclically to individual sensors. The sensors operate in multiplex mode.<
