Ultrasonic proximity sensor

The ultrasonic proximity switch UPL 200 of SNT Sensortech-nik AG is designed for de-tection in the close range up to 200 mm.

It has a fixed switching distance and no setting elements. Thus it is suitable for lateral approximation of objects, for example, on conveyors.

The UPL type detects most objects also in the blind range due to its high power Son-arange transmitter and the M30 surface, ie, in the whole range from 0-200 mm. Only bad reflecting (eg, some tex-tiles) or very small objects (<15 mm) can be detected only at higher distances.

Thus for most objects the sensor works without blind zone. Due to this feature it is an alternative to conventional inductive, capacitive or op-tical proximity switches.
