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 detection via a TTL compatible push pull switch like output. They are designed for price-sensitive, high volume OEM applications. The liquid sensor provides a low power signal, making these optical switches ideal for microcontrollers when needing to detect the absence or presence of non-coating, clean liquids. An infrared LED and phototransistor ensure 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 output state.
