Typical installation: Customer has to select suitable resistors for their chosen supply voltage. Forward voltage of LED is 1.3V and

LED current should be 10mA (depending on application liquid). Therefore, for a supply of Vs:

This liquid presence sensor has been developed to address the needs

of high volume OEM applications. The sensor contains an infra-red

emitter and detector accurately positioned to ensure good optical cou-

pling between the two when the sensor is in air. When the sensor’s

cone is immersed in liquid, the infra-red light escapes from the cone

causing a change in the amount of light at the detector.

This configuration allows the customer to tailor the sensor electronics

(supply, protection etc.) to their unique application.
