Long Distance and Non-Contact Proximity Detection with Ultrasonic Sensors

Using “non-contact” technology, Senix ToughSonic® Ultrasonic Sensors can detect objects or materials through the air. They are reliable and most importantly easy to use. Almost any material can be detected: soft or hard, any color, opacity or transparency, flat or curved. They function over longer distances, unlike run-of-the-mill proximity sensors, and can be set-up to limit object detection within a user-specified distance band (“window”).

Presence/Absence

Object detection is a type of proximity sensing with the ability to determine if an object or material is present (arrives) or absent (disappears).

Distance Discrimination

Configuration of Senix ultrasonic sensors can be carried out to regulate object detection to a user-configurable range of distances. Additionally, they can also be configured to determine a single maximum range of detection within the sensor’s maximum range. This enables the sensor to disregard objects further away that may be permanently or intermittently within the sensor’s maximum range.

The Sensors

ToughSonic sensors can take abuse in both indoor and outdoor conditions. With no mechanical parts to break, robust electronic components are potted with epoxy into small stainless steel housings. IEC-compliant electrical interfaces are protected from reversed connections and over-voltages.

These proximity sensors are widely compatible with an easy set-up for all common automation equipment. Applications range from PLC inputs, ON/OFF switches, to relay connections, and multi-sensor detection networks. They are cost effective, with many features built into the sensor’s software – user-adjustable power that can be unlocked with SenixVIEW PC software.

Object Detection Applications

Ultrasonic proximity sensors can be found in a wide range of scenarios and applications where the presence or absence of a material, object or person is a vital component in the control of a machine or process. They are typically found in robotics, converting, printing, material handling, and transportation industries.
