Magnetic proximity sensors 3.4 Exercises Exercise 3.1 Maximum passing speed Calculate the maximum passing speed of a cylinder piston, the position of which is to be sensed by means of a reed contact. To do this, assume that the switching time of the proximity sensor used is 2 ms and take the response travel from table 3.4.1. Calculate the value for a Festo cylinder, type DNNZ with a diameter of 32 mm as an example. What is the change in maximum speed if, for instance, a valve is to be switched with a switching time of 15 ms?
