The OPB360N51 is a photointerrupter, specifically a slotted type, and has transistor output type. It is an optical coupler consisting of a gallium arsenide infrared emitting diode and a high speed NPN silicon phototransistor. It is an ideal choice for paper and PCB level identification and counting applications. Furthermore, it is also suitable for optical proximity sensing, data transfer and low-level electrical isolation.

The OPB360N51 consists of an infrared LED placed in the receiver of the optocoupler and a phototransistor mounted in an integrated package. The optocoupler is designed so that the LED emits a light beam which is directed to the phototransistor, which is also positioned in the receiver. The light beam is interrupted by any object placing itself between the optocoupler and the phototransistor, the interruption causes the phototransistor to open and an electric signal is sent through the circuit. When the object is removed the light beam is restored and the phototransistor will close again, producing a new electrical signal.

The OPB360N51 works by detecting the presence of an object. When the light beam is interrupted, the electronic signal is detected and the optocoupler can be used to detect the presence or the absence of an object, depending on the type of output signal. For instance, when the signal output is in the form of a digital signal, the optocoupler can be used to detect whether an object is present or absent, since a digital signal will either be high or low, depending on the presence of an object. Likewise, the optocoupler can be configured to output an analog signal, which can be used to measure the distance of an object from the optocoupler.

The OPB360N51 can be used in a wide range of applications, including paper and PCB level identification and counting, optical proximity sensing, data transfer, contactless triggering and low level electrical isolation. Additionally, it is extremely reliable and has a long life expectancy due to its low power consumption and built-in protection against voltage spikes and transients.
