Optical sensors are a type of sensor that uses light beams in order to determine the distance, position, or motion of an object. Photointerrupters are a type of optical sensor that are used to detect and measure linear displacement of an object. A slot type photointerrupter, also known as a slotted optical switch, is a type of photointerrupter that uses a vertical slot to detect and measure linear motion. The OPB890P51Z is a slotted photointerrupter that features a compact package and a transistor output.

The OPB890P51Z is used in various applications that require precise and reliable detection of linear displacement. These applications include level detection of various items such as fluid levels in tanks, conveyor systems, position detection in medical equipment, and industrial automation. These applications are mainly used in automotive, medical, consumer, and industrial sectors.

The OPB890P51Z works by using a vertical slot to detect and measure linear motion. It consists of an infrared emitting diode and an NPN phototransistor. The diode emits a beam of infrared light towards the phototransistor, and when an object passes through the vertical slot, the beam is interrupted and the phototransistor registers a decrease in light intensity. The phototransistor then outputs a voltage level that is proportional to the interruption of the beam of light. By detecting the change in voltage level, the device is able to accurately measure and detect linear displacement of objects.

The OPB890P51Z is capable of detecting objects as small as 0.3mm and can respond to interruptions as fast as 2μsec. It has a compact 6-pin SIP package and features a built-in emitter shutter, making it suitable for use in various applications. It also has a wide voltage range and is desensitized to guarantee reliable operation even when the input voltage is increased. The transistor output of the device makes it easy to connect to other electronic components.

In conclusion, the OPB890P51Z is a transistor output slot type photointerrupter that is used for detecting and measuring linear displacement of objects in various applications. It features a compact package, a built-in emitter shutter for reliable operation, and a wide voltage range. It is capable of detecting objects as small as 0.3mm and can respond to interruptions as fast as 2μsec. This makes it suitable for use in various industries such as automotive, medical, consumer, and industrial.
