The compact ultrasound sensors of the ARKS series, at 26x40x12 mm, are about the size of a matchbox. They have a switching distance of 25 mm to 250 mm. Thanks to their narrow sound cone, even small objects can be detected reliably. For instance, the fill level can be determined reliably in narrow tubes of tablets. These sensors are waterproof to IP 67 and are connected with an M8 plug system. The switching point is programmed as an NO or an NC contact.
