Electronic switch, e.g. inductive, capacitive or opto-electronic proximity switch - has switching distance set through external terminals and voltage supplied from external source

摘要

The proximity switch has at least one element (7) which can be set to fix the switching distance. The switch determines the magnitude of the distance according to its state, and at least two external terminals which can be used. The state of the element and so the switching distance can be set through the external terminals (8, 9, 10) and the voltage supplied to the equipment from the network voltage or the voltage source (12). Different voltages are possible and at least one control signal can be obtained for setting the state of the element which then is able to adjust the working of the two oscillators (1, 2). ADVANTAGE - Switching distance can easily be set.
