Unformatted text preview: cylinder piston across a reed proximity sensor The maximum passing speed for a piston is calculated using formula: vmax = Smin / TS Smin is the smallest possible response range of the proximity switch when overtravelled by the cylinder piston. TS is the switching time of the proximity sensor or of another affected part, e.g. a valve. In this instance, the result obtained from the data sheet of the reed proximity sensor (SME) is the value TS = 2 ms for the response time of this component. A value of 7 mm is obtained from table 16.2.1 in respect of the Festo cylinder DNNZ with a diameter of 32 mm for the response travel. For vmax a value of 3.5 m/s is obtained. © Festo Didactic GmbH & Co. KG • FP 1110 253 16.
