LLC200D3SH Optomax Digital Series 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.
The TTL compatible push-pull output can sink and source up to 100mA at a supply voltage range of 4.5 to 15.4Vdc and can be configured to output a high or low signal when in either a wet or dry state. A fail-safe PWM option is also available with a supply voltage range of 4.5 to 5.5Vdc.
With housing options for internal or external sensor mounting and for use in two operating temperature ranges; Standard (-25 to 80°C) or Extended (-40 to 125°C).
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.
