Description
Fork barriers have several advantages compared to standard
barriers. Transmitter and receiver are perfectly aligned.
Mounting is therefore very easy. There is no mechanical
misalignment possible after mounting.
Ultrasonic fork sensors in particular, are ideal if optical fork
sensors fail because of high pollution or transparent objects.
The UPF-B fork sensor is compatible with optical fork
sensors from point of view of installation as well as operation.
It is suitable for detecting parts or for edge detection, and has
a switching speed of 500Hz which is very high for ultrasonic
sensors. Thanks to the new transducer sealing made of
Viton
®
the UPF-B sensors are very robust against many
environmental influences. In particular, they are oil resistant,
unlike many other ultrasonic sensors.
