Unformatted text preview: sponse time
Delay time between the actuating element entering into the active zone of a
proximity sensor and the signal change at the output. The speed at which the
actuating element could pass through the active zone is limited in relation to the
width of the actuating element.
Duration of the output signal with dynamic actuation. This must correspond to the
input delay of the connected load. 208 © Festo Didactic GmbH & Co. KG • FP 1110 13. Technical terms relating to proximity sensors Switching frequency
