WMS ultrasonic sensors

The wms- ultrasonic sensors are equipped with an echo signal output. The customer is responsible for providing a signal and reading the values. In contrast to standard ultrasonic sensors, the WMS sensors are not equipped with a microprocessor. This makes the wms ultrasonic sensors a cost-effective solution.
The sensor signal input is momentarily connected to -UB via an open-collector circuit through the customer's control system. The echo signal output then transmits all echo signals received as 1-bit values (echo yes/no) depending on their duration. This takes between 8 and 65 ms, depending on the type of sensor. The distance calculation and subsequent processing of the signal is also performed in the user's operating system.
