LLT600D3SH Liquid Level Switches General Description Optomax Digital liquid level switches are ideal for applications with restricted space that require a miniature, low power and low cost sensing solution. The microcontroller based sensor is solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid. Available in two chemically resistant housing materials, Polysulfone, the standard choice for most applications or Trogamid, which is typically used in food and beverage applications.
