Optical sensing plays a major role in precision motion control applications, and photoelectric sensors are commonly used to detect the movement of objects. The OPB820S5 optical sensor is a slot type photointerrupter with a built-in transistor output that makes it easy to connect to and interface with an external circuit.

The OPB820S5 optical sensor is designed to detect objects and objects moving in a specific direction. It consists of an infrared LED and an NPN/PNP output photo-transistor that are arranged in a side-by-side configuration. The photo-transistor acts as a receiver and is mounted on a pivot, allowing it to detect objects passing through a narrow slot. The narrow slot increases the signal-to-noise ratio, providing better accuracy and sensitivity.

The OPB820S5 optical sensor is an ideal solution for applications where objects need to be accurately detected in a limited space. It is particularly suitable for use in pick-and-place applications, where the detection of objects needs to be very precise. The OPB820S5 is capable of detecting objects in a range of 0.5 to 6mm, making it well suited for use in such applications.

The OPB820S5 optical sensor features a low power requirement and high response speed. The sensor operates on just 3mA of LED current, and its response time of 0.1ms ensures that objects are accurately detected. The LED can be driven with either an AC or DC voltage, and the output of the photo-transistor can be interfaced with TTL, MOSFET or Logic ICs.

The OPB820S5 optical sensor is a versatile solution for applications where precise object detection is needed. Its adjustable slot size enables it to detect objects of various sizes, while the fast response time ensures accurate and reliable detection. Coupled with its low power consumption, the OPB820S5 is an ideal choice for use in precision motion control applications.
