OPB660N Application Field and Working Principle

The OPB660N is an optical sensor device known as a "Photointerrupter". It belongs from a larger family of products known as "Slot Type" Optical Sensors, which are characterized by a two-piece construction with an LED emitter and a photosensitive / photodetector. The photointerrupter or the OPB660N, however, uses a transistor output as its sensing mechanism instead of a mechanical switch.

The OPB660N has been designed for the detection and monitoring of multiple objects. It works by utilizing infrared light to detect an object, breaking the beam, and hence, triggering an electrical output. Internal circuitry also optimizes the signal emitted by the LED emitter, allowing it to detect objects in close and far work areas. As such, the OPB660N is an ideal device for use in any application where object and material presence, or absence needs to be known.

In terms of assembly, the OPB660N consists of two parts, namely the LED emitter and the photosensitive component. An onboard drive circuit is then fitted on the device for controlling the drive current. During operation, an infrared light beam is transmitted from the LED emitter, passes through the slot area on the OPB660N, and reaches the photosensitive component. If an object passes through the slot, the light beam is partially interrupted, and the photosensitive component detects this, leading to a signal output from the OPB660N. A massive variety of objects can be detected with the OPB660N, ranging in size from a few centimeters to several feet.

The set-up also allows for accurate gain adjustment, eliminating the need for external components. And the onboard circuitry also enables noise-immunity in the few nanoseconds range. The fast response time, exceedingly long busbar life, as well as its relatively low power consumption further expand its capabilities as an optical sensor. About a few pulses of the signal output can be detected even in the presence of electrical noise. This helps to provide reliable detection over long periods of time, making the OPB660N a reliable sensor for many applications.

Due to its highly reliable performance and versatile capabilities, the OPB660N has been used in a wide range of applications, such as industrial robot control, automotive safety systems, medical imaging systems, and even office automation systems. It is also used in vending machines, optical data reading, and a great variety of other applications. The OPB660N\'s modular design further allows it to be integrated with machines, allowing for seamless operation with devices such as smartphones and P.C.s.

The OPB660N Optical Sensor is a remarkable device, having revolutionized the way objects and materials are detected in the industry. One of the most versatile and excellent devices in Transistor Output Slot Type Photointerrupters, the OPB660N is the ideal choice for most applications. With its high level of performance, affordability, and dependability, the OPB660N is sure to be used in many more applications in the years to come.
