摘要

The operating parameters of a proximity switch can differ depending on type and due to production tolerances. To be able to respond to new developments in ultrasonic transducers and to customer-specific solutions, a device and a method are to be created by means of which the data input of operating parameters into a microprocessor of a completely assembled proximity switch is possible with little expenditure and without additional space requirements. This is based on a proximity switch (1) which contains an enable input (2) and an overcurrent monitoring device (3) with a microprocessor (4). An overcurrent (7) at the switching output can be signalled to the microprocessor via an associated first input (5) by means of a pulse. To achieve the object, means (8) for loading are provided by means of which such an overcurrent state is simulated and the corresponding pulse (6) is generated which represents an information item of an operating parameter in the form of a bit pattern. The microprocessor (4) is loaded with this pattern. The enable input (2) is used for synchronising the microprocessor (4) to first synchronising pulses (9).
