Contrinex ultrasonic sensors provide reliable, non-contact detection of solid,liquid, granular or powdered materials in air, tolerating precipitation, humidity, dust and fumes. Target materials may be colored, transparent, polished or matt; detection is practically independent of the target’s direction of travel. Diffuse-mode and reflex sensors emit bursts of high-frequency sound waves toward a target, measuring the time elapsed until an echo is received. They contain a transmitter and a receiver in a single housing. Ultrasonic sensors are compensated for temperature variation, but are unsuitable for use with very hot targets. The technology is ideal for distance measurement and presence- or proximity-detection at moderate distances.
Ultrasonic Diffuse
With diffuse sensors, the target itself reflects the ultrasonic impulses. When the target enters a preset sensing area, the echo reflected from it causes the device to switch. To eliminate false switching, the Contrinex ultrasonic Diffuse family...

Ultrasonic Reflex
In the case of reflex sensors, a fixed reflector (e.g. a small metal plate) is mounted facing the device. The switching range is set to this reflector. If an object comes between the ultrasonic sensor and the...
