Optical Sensors, of which Photointerrupters are one type, are devices used to detect the presence and absence of objects through the use of light. They can be used to measure the duration, position, angle, and speed of an object. Slot Type Optical Sensors contain an emitter and a receiver, both of which are enclosed within a single housing. OPB860N55 is one type of Slot Type Optical Sensor with Transistor Output.

Application Field

OPB860N55 is an ideal detection solution for a variety of application fields, such as automotive, industrial, medical, and consumer electronics. Specifically, this type of Optical Sensor can be used for applications in automotive including airbag systems, brake shoe switching, and collision warning systems. In industrial process automation, it can be used for automation control, line scanning, and monitoring of moving parts or conveyor belts. It is also popular in consumer electronics devices, for example, printers, camcorders, scanners, and robots.

Working Principle

The OPB860N55 works according to the principle of transmission and reception of light. It has two parts, the transmitter and the receiver, each integrated in one small housing. The transmitter is a Light Emitting Diode (LED), which emits light towards the receiver when it is switched on. When an object passes through the slot, the light is blocked and the receiver no longer detects it, sending an electric signal to the electronic software for further processing. The signal can be used to detect the presence or absence of the object passing by.

The OPB860N55 has a high resolution of less than 10 μm, as well as a fast response time of less than 1 μs. Its small size allows for easy integration with other equipment. Moreover, the sensor can withstand temperatures up to 100°C and has a good moisture resistance. It also features low voltage operation, and an extended operating temperature range from -30°C to +85°C, which can meet the needs of many applications.

The OPB860N55 can provide reliable sensing and detection performance over a long period of time. This makes it an ideal choice for a wide range of industrial automation and consumer electronics applications that require accuracy and reliability.
