Optomax Basic Range of Liquid Level Switches

The Optomax Basic range of liquid level switches are an analogue optics only solution designed to meet the demand of price sensitive, high volume OEM applications.

The miniature sensor is solid state, containing only 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 phototransistor output change state. The sensor can detect the presence or absence of almost any liquid type, oil or water based.

Because the Optomax Basic range of liquid level switches only contains Optoelectronic components the customer is responsible for interfacing the sensor to their application with technical support from SST. OEM applications can be very price sensitive so by removing the circuit protection, voltage regulation, processing electronics and output stage, the sensor cost is significantly reduced. Available in 3 wire (common cathode/emitter) and 4 wire (galvanically isolated) configurations.

With housing options for internal or external sensor mounting and 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.

The Optomax Basic Range of liquid level switches are only sold in high volumes and have an minimum order quantity of 100 units.
