Object Detection Sensor Applications

Senix ToughSonic® Ultrasonic Sensors detect objects or materials through the air using “non-contact” technology. They are easy to use and reliable. Most materials can be detected: hard or soft, any color or transparency, flat or curved. Unlike traditional proximity sensors, they operate over longer distances and can be set up to limit object detection within a user-specified distance band (“window”).


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

Distance Discrimination

Senix ultrasonic sensors can be configured to restrict object detection to a user-configurable range of distances. They can also be configured to establish a single maximum range of detection within the sensor’s maximum range. This allows the sensor to ignore further objects that may be permanently or intermittently within the sensor’s maximum range.

What our customers say…

Excellent service as always.  I already have the kit and it updated the firmware without a problem. Thanks again.

Whether used indoors or out, ToughSonic sensors can take abuse. Rugged electronic components are epoxy potted into small stainless steel housings, and there are no mechanical parts to break. IEC compliant electrical interfaces are protected from reversed connections and overvoltages.

These proximity sensors easily connect with all common automation equipment. Applications range from simple ON/OFF switches to relay connections, PLC inputs and multi-sensor detection networks. They are cost effective, with many user-adjustable features built into the sensor’s software – power that you can unlock with our SenixVIEW PC software.

Object Detection Applications
Ultrasonic proximity sensors are found in applications where the presence or absence of a material, object or person is important in the control of a machine or process. They are commonly found in printing, converting, robotics, material handling and transportation industries.
