Unformatted text preview: y sensors as a rule are equipped with a light emitting diode for status indication and very often with a potentiometer for setting of the operating range. There are also designs with two potentiometers for setting a switching window as well as special programmable designs, with which different operating ranges can be selected via an electronic interface. Some ultrasonic proximity sensors are equipped with synchronised inputs, whereby trouble free and alternating operation is possible if several adjacent proximity sensors are used. 110 © Festo Didactic GmbH & Co. KG • FP 1110 7. Ultrasonic proximity sensors 7.3 Notes on application 7.3.1 Minimum distances With the installation of ultrasonic proximity sensors, as with that of inductive and capacitive sensors, different minimum distances must be observed between adjacent proximity sensors. When assembling ultrasonic proximity sensors without the option for synchronisation, make sure that mutual influence of the proximity sensors does not occur. Observe the following listed minimum distances in relation to the detection range of the proxi...
