You are using a capacitive proximity sensor on an outdoor installation.
What do you need to remember, particularly in the spring and autumn? Exercise 5.3 Detection of cardboard boxes
You intend to use a capacitive proximity sensor for the detection of cardboard boxes
of varying material thickness.
What do you have to remember? Exercise 5.4 Detection of a transparent panel
In a factory producing food products, the presence of a panel made of transparent
film is to be checked on empty cardboard packaging (see fig. 5.5.1). You are not sure
whether to use a capacitive, an optical or an ultrasonic proximity sensor.
What are your arguments for this? 1 2 Transparent panels 50 x 30 mm, Cling film 0.1 mm thick (1) Cardboard packaging (2) Fig. 5.5.1: Packaging with transparent panel © Festo Didactic GmbH & Co. KG • FP 1110 69 70 © Festo Didactic GmbH & Co. KG • FP 1110 6. Optical proximity sensors 6.1
