Cylinder|Ultrasonic Sensors|for industrial use
- Ultrasonic Proximity Sensor 9.449" ~ 157.48" (240mm ~ 4000mm)
Ultrasonic waves are used to enable stable detection of transparent objects, such as transparent films, glass bottles, plastic bottles, and plate glass, using Through-beam or Reflective Sensors.
Features:
High-precision detection with a wide range of measurements.
Four types of Sensors are available with maximum sensing distances of 0.5 m, 2 m, 4 m, and 6 m. With the 0.5-m type, a repeat accuracy of 1 mm or better has been achieved.
The Sensor is ultrasonic, so it is not affected by the color of objects.
A variety of materials can be measured, including transparent and reflective objects. Measurements are performed with no contact, so even highly-viscous liquids are no problem.
A setting plug with a temperature compensation function makes it easy to set the sensing range.
The sensing range can be set by the Setting Plug, which is included with the Sensor. No special controller is required. The Setting Plug’s built-in temperature sensor provides superior temperature characteristics of ±1% FS.
The mutual interference prevention function allows up to five Sensors to be used in close proximity.
