They are ideal for a variety of point level sensing applications where reliability and low cost are desired.
These level switches use infrared technology for their operation.
They consist of an infrared emitter and an optical receiver. They have an operating temperature range of -40 to 85 deg C. There is a programmable timer inside these K04 level switches that allows a delay time to be set for delaying the output switching.
The output mode is normally closed or open in air and the output current (DC or AC) is up to 100mA depending on model
The K04 level switches must not be installed close to any infra red sources.
The dome must be at least 50mm away from any reflective surface.
These level switches have electronic protection against transient over voltage, reverse polarity for DC models and output short circuit.
The K04 family of level switches have a detection accuracy of +/- 2 mm. They can withstand maximum pressure of 40 bars.
