Optical sensors are devices that detect changes in light intensity to send an electrical signal in response. These optical sensors are commonly used for sensing a variety of applications, including industrial automation, robotics, and consumer electronics. Photointerrupters are one type of optical sensor, and the OPB970N51 is a slot-type photointerrupter with a logic output. In this article, we will discuss the application field and working principle of the OPB970N51.

OPB970N51 is a reflective optical slot sensor that can be used for the detection of small objects. It is widely used in industrial automation, robotics, and consumer electronics. The slot-type design of the sensor allows it to detect objects within a fixed distance, making it ideal for applications requiring precise detection. The sensor is made up of an infrared LED that emits light and an optical IC that detects changes in light intensity. The light from the LED is directed into the slot and reflected back to the IC by the object. This changes the amount of light detected by the sensor, allowing for the detection of objects in a specific maximum distance.

The main principle of the OPB970N51 is to detect objects within a certain maximum distance. The detection range is determined by the size of the slot, the angle at which the LED transmits light, and the sensitivity of the optical IC. The detection angle is adjustable from 11 degrees to 360 degrees. This allows the sensor to detect objects at different angles and distances. The output of the sensor is a logic output, which indicates whether an object has been detected. The output can be set to either high or low depending on the threshold of the detection distance. The sensitivity of the sensor can also be adjusted to detect objects in different distances.

The OPB970N51 optical slot sensor is designed to be used in many applications, including factory automation, robotics, conveyor systems, door locks, and consumer electronics. This sensor is also used in applications where objects have to be detected quickly and reliably. In factory automation, the sensor is used to detect the presence or absence of objects on a conveyor belt. In door locks, the sensor is used to detect a user located within a certain distance of the door. In consumer electronics, the sensor is used to detect the presence or absence of a remote control or other device.

The OPB970N51 is a reliable, accurate, and cost-effective sensor for object detection in a range of applications. Its slot-type design allows for precise detection of objects within a specific distance. The adjustable detection angle and sensitivity allow for flexible control, making it suitable for a wide range of applications. Its logic output enables easy integration with existing systems, making it an ideal choice for many industrial automation, robotics, and consumer electronics projects.
