Optoelectronic Level Switch - OLS-C01

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
The model OLS-C01 optoelectronic level switch is used for monitoring the level of liquids. The optoelectronic sensor consists of an infrared LED and a light receptor.

The light from the LED is directed at a prism which forms the tip of the sensor. So long as the tip is not immersed in liquid, the light is reflected within the prism to the receiver.
Features
  • Compact design, no moving components. 
  • Mounting position as required. 
  • Accuracy ±2 mm. 
  • Visual indication of the switching status. 
  • Choice of electrical connections: PUR, PVC cable or circular connector M8.
