 Small ultrasonic scanner in plastic housing

with protection class IP67

 Various opening angles and sound cone

geometries

 Switching behavior largely independent of

surface properties

 Precise switching point adjustment through

teach-in on the device and via a cable

 Protection against erroneous operation by

automatically locking teach button

Accessories:

(available separately)

 M8 connectors (D M8…)
 Ready-made cables (K-D …)
