Plastic Optical Sensors

optical-plastic-miniOPT Series: 5-12 vdc Miniature Optical Level Switch

This miniature plastic liquid level sensor provides a single point liquid de-tection via a TTL compatible push pull switch like output. Designed for price sensitive OEM applications. The liquid sensor provides a low power signal, making these optical switches ideal for microcontrollers, when need-ing to detect the absence or presence of non-coating, clean liquids. An infra-red LED and phototransistor ensures dependable optical coupling when the sensor is in air to prevent false readings. When the sensing tip is immersed in liquid, the phototransistor senses the liquid to switch the out-put state.
