Optical Sensors - Reflective - Analog Output are used in a wide variety of applications. This type of optical sensor detects changes in the reflected light on the surface of the object being sensed and converts them into an analog electrical signal. They are often used to measure distances and levels in harsh industrial environments, or where light conditions vary. The CNY70 is an example of this type of reflector-type analog output sensor which has been developed to cater for many dynamic applications.

The CNY70 consists of an infrared emitter (LED) and a phototransistor detector, and is housed within a one-piece package with an opaque black lens cover. The black coating helps to prevent ambient light interference, which makes the sensor suitable for use in brightly lit and variable light conditions. The device offers an adjustable sensing range, making it suitable for a range of sensing applications.

CNY70s measure the distance between the sensor and the target by using the intensity of the reflected infrared light. The LED emits infrared light which is focused into a cone and is then directed at the object being detected. The infrared light is then reflected back and detected by the phototransistor. The intensity of the reflected light is proportional to the distance between the sensor and the object being detected and is used to calculate the absolute distance.

CNY70 optical sensors are ideal for a variety of applications, such as level sensing, distance measurement and position sensing in industrial automation and robotics applications. The sensors are shock-proof and vibration-proof, and they are also highly reliable and accurate. The compact size of the CNY70 makes it particularly suitable for space-critical applications. The CNY70 is a cost-effective solution and can be used in a wide range of environmental conditions.

The CNY70 operates using a 5V DC input voltage and produces an analog voltage output proportional to the reflected infrared light. The analog output voltage can be read by the user to measure the distance between the sensor and the object being detected. Both the emitter (LED) and the phototransistor are connected to a common output. The LED is powered by a voltage source of up to 90 mA, and the phototransistor is powered by a current source of up to 500 mA.

The CNY70 can be programmed for increased sensitivity, narrow window detection or long range detection, depending on the application\'s requirements. For instance, the sensitivity can be programmed to detect the presence of a specific type of material such as wood, metal or plastic. The CNY70 also offers the user the flexibility to choose between two different types of analog output signals: either DC voltage or frequency.

In conclusion, the CNY70 is a highly reliable and versatile optical sensor that is suitable for a range of dynamic applications and environments. The device offers a range of adjustable features and provides an analog voltage output that can be used to measure the distance between the sensor and the target. With its shock and vibration proof design and compact size, the CNY70 is an ideal solution for industrial automation and robotics applications.
