Optical sensors are devices that convert light signals transmitted from an object into electrical signals. Photointerrupters are a type of optical sensor and they are used to detect the presence or absence of an object by interrupting or detecting a beam of light. The OPB865P55 is a slot type photointerrupter with transistor output, specifically, it is a wide-slot type with infrared LED and photodetector module, which outputs a digital signal after interruption.

The OPB865P55 has several applications, including but not limited to: switch interface, motor speed monitoring, motion control systems, security systems, and flow monitoring. The device is ideal for applications where an object interrupts the optical beam from the LED and the photodetector senses the interruption. The OPB865P55 then sends a digital signal to the control system promptly and accurately.

In terms of its working principle, the OPB865P55 consists of an infrared LED and a photodetector. The LED, on one side of the device, emits a beam of infrared light across the substrate, towards the photodetector on the other side of the device. When an object interrupts the infrared beam, the photodetector detects the interruption and sends a signal to the control system. This signal currently has two output forms: an Open Collector that switches off in the absence of an object, and a Transistor Output that switches on in the absence of an object. The Open Collector output can be threshold-adjusted to operate at 3.1mA for “ON” and 0.1mA for “OFF”, with an output voltage of 70V. The Transistor Output, on the other hand, has a minimum saturation voltage of 0.2V and a maximum saturation voltage of 1V.

The OPB865P55 has a wide slot width of 8.65mm and a height of 1.55mm, ensuring a high level of accuracy and performance in any application. In addition, the device is equipped with built-in noise suppression circuitry, making it ideal for noise-sensitive applications. It also features an easy-to-use LED indicator which lights up when an object is detected. The device is designed for easy mounting onto many surfaces and has two mounting options: panel and snap-in.

The OPB865P55 is a slot type photointerrupter with transistor output that is ideal for applications where an object interrupts the optical beam from the LED and the photodetector senses the interruption. The device is easy to mount and has built-in noise suppression circuitry, making it perfect for noise-sensitive applications. The OPB865P55 is used in a variety of applications from motor speed monitoring to flow monitoring, offering high levels of accuracy and performance.
