Unformatted text preview: check whether the slide of a feeding device is in one of two normal end positions 4.5 Exercises Exercise 4.1 Application of an inductive proximity sensor The number, distance and direction of transport of material containers are to be checked on a conveyor belt. For the purpose of marking, the transport containers are provided with an aluminium marking plate. What do you need to consider when selecting an inductive proximity sensor for this task? How do you achieve the largest possible switching distance for a given sensor diameter? What do you need to pay particular attention to in this instance? What is the positive influence of the hysteresis on the switching behaviour of an inductive proximity sensor? Consider what you would need to observe in practice if switch-on and switch-off point were exactly the same distance from the proximity sensor. 58 © Festo Didactic GmbH & Co. KG • FP 1110 4.
