Optical Sensors - Reflective - Analog OutputThe CNB1301 is an optical sensor designed to detect the presence or absence of objects in industrial automation applications. It is an analog, reflective type optical sensor that utilizes a single photodiode and a light source. It is composed of an infrared LED emitter and an infrared photodiode in an enclosed package. The device uses an infrared light source to detect the presence or absence of objects in the field of view of the sensor. When no objects are present, the light is reflected from the surface of the object and the photodiode detects this reflection, producing an analog output voltage signal. When an object is detected, the surface Reflects the light back to the opto-coupler and the photodiode detects the reflection, producing an analog output voltage corresponding to the intensity of the object detected. The CNB1301 is ideal for detecting small objects such as cables, wires, and printed circuit boards. Its reflective sensing mechanism enables the sensor to detect objects even in difficult environments, including dusty and oily manufactured products. Its output is a current or voltage signal that is proportional to the amount of light being reflected from the object. The sensor is capable of adjusting its sensitivity to meet the demands of the application. The output signal of the device can be further adjusted via its adjustable sensitivity. The CNB1301 optical sensor works in a unique way. First, the infrared LED emitter is turned on and emits light in the direction of the object that is to be sensed. If no objects are present, the surface of the area reflects the light back to the optical sensor where it is picked up by the photodiode. The photodiode then converts the light to an analog voltage signal. If an object is present, the light is reflected back to the surface of the object, and the photodiode detects this reflection and produces an analog output voltage signal based on the intensity of the object detected. The level of the total light reflected by the object determines the amount of light that is then converted to a current or voltage output signal.The CNB1301 has several features that make it ideal for industrial automation applications. It is designed for durability and long life in harsh environments. The digital output signal of the device is low noise and reliable, which is an advantage when used in computer-controlled applications. The output signal is also highly adjustable, meaning that it can be adjusted to meet the demands of the application. The CNB1301 is an excellent choice for detecting and monitoring objects in industrial automation applications. The low cost, flexible, and reliable output signal of the device makes it an ideal choice for applications involving the presence or absence of objects.
