Optoelectronic Level Switch - OLS-C05
Brand: WIKA Instruments Ltd.The model OLS-C05 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- Use at temperatures of up to +170 °C.
- Mounting position as required.
- Accuracy ±2 mm.
- Visual indication of the switching status.
- Choice of electrical connections: PUR, PVC cable, circular.
- connector M12 x 1 or angular connector EN 175301-803 A.
