The OPB961T51 photointerrupter, manufactured by Optek Technology, is an optical sensor and part of the company\'s Slot Type Logic Output family. The OPB961T51 is designed to detect the presence of objects or to count objects using an infrared light detection methodology. By utilizing the OPB961T51, engineers can facilitate working with applications that require a logic output signal.

The application field of the OPB961T51 is based around industrial automation, such as the detection of objects on a conveyor belt, the counting of products, and the divide control of them. The device is designed for high efficiency of detection and long operation life. It can also be used for the detection of liquids and liquids level controls, ideal for applications involving high temperature, dust, and vibration.

The OPB961T51 is a slotted-type photointerrupter that consists of an infrared LED and a phototransistor encased in an opaque plastic molded housing. The device utilizes a slotted interrupter design that requires two detect lines to operate, the first line for the emission of infrared light, the second line to detect the object that interrupts the detection line. The output is a logic "on" state when the infrared source is detected.

The working principles behind the OPB961T51 is based on the principle of opto-islolation----by emitting infrared light from the LED and the capturing and conversion of light in an enclosed space by the phototransistor, the OPB961T51 can detect objects or count objects that pass through its detection range. The detection range of the device is specified at a maximum 200mm distance from the source.

The versatility of the OPB961T51 is further increased by its electrical characteristics, which are compliant with commercial standards. Its maximum isolation voltage rating is 5,000V RMS, and it has a response time of 2.0 microseconds for on/off motions. It also has a package size of only 18.4 mm x 11.3 mm x 10.4 mm, making it an ideal choice for tight spaces. In addition, the OPB961T51 features an open-collector type output which allows for easy detection of any type of object.

The OPB961T51 is a reliable and versatile photointerrupter which can provide a logic output signal to detect the presence of objects or to count them with precise accuracy. It is designed to provide high efficiency of detection and operation life, and can be used for applications that require a logic output signal in challenging environments such as dusty or wet conditions, high temperatures, and vibration. The device also has an open-collector type output, which allows for easy detection of any type of object.
