Edge Position Control Systems(Sensors) Ultrasonic Autowide Sensor UHW280 Overview |　 Feature |　 Specifications |

Overview

Consistently detects changes in the edge position of transparent/thin/reflective webs - over a wide field of view.

The ultrasonic Autowide sensor is able to detect -- over a wide field of view -- the edge of webs that are transparent or are thin films or have other qualities that make them difficult to be detected by optical sensors.
Not only is the ultrasonic Autowide sensor UHW280 resistant to changes in ambient temperature and humidity, this sensor for the detection of meandering web edges has outstanding features, including a function that automatically corrects the level of ultrasonic transmission when the thickness of the detected web changes.
The ultrasonic Autowide sensor UHW280 is a meandering web edge detector that saves time and labor, and is easy to use.

Feature
Even if the detected material changes, the automatic thickness compensation function enables optimal detection
An effective detection field of view of 280 mm
An automatic correction function which minimizes the influence of changes in ambient temperature and humidity
Can detect the edges of thin transparent films (3 μm or greater) over a wide field of view
