Industrial Liquid Level Switch - SST Optomax Industrial Range Industrial Grade Level Switch Sensors Packaged in Chemically Resistant Housing Features • Reverse polarity ESD, transient over-voltage and short circuit protected • Wide supply voltage ranges • N and P type output configurations, capable of sinking or sourcing up to 200mA, can directly drive small loads • Standard and extended temperature ranges available • Various mounting threads available • LED output indication The Optomax Industrial level switch was designed to offer industrial supply voltages and outputs that can directly drive higher power loads. 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. A range of N and P type output configurations can sink or source up to 1A at supply voltage ranges from 4.5 to 15.4Vdc or 8 to 30Vdc and can be configured to output a high or low signal in either a wet or dry state. Options for connecting to inductive loads or digital interfaces are also available. With housing threads suitable for external sensor mounting and for use in two operating temperature ranges; Standard (-25 to 80°C) or Extended (-40 to 125°C).
