OPB891L51Z is an optoelectronic Slot-Type Transistor Output Photointerrupter from Sharp. It is mainly used in sensing operations such as sensing of paper movement for photocopiers, documents, and any other type of paper media. This device is capable of making precise measurements and allows for faster processing time when compared to other sensors.

The OPB891L51Z consists of a transmitter and a receiver which are spaced apart through a measurable distance such as a groove or a slot. An infrared beam is emitted from the transmitter which is focused on to the receiver. The receiver converts the incident light to an electrical signal, usually in the form of a logic pulse. This logic pulse is then fed into subsequent circuitry or processing unit.

The operating principle of the OPB891L51Z is based on the use of light interruption to detect the supply or presence of a paper or object being monitored. This is achieved through the use of a light emitting diode (LED) and a corresponding integrated photosensor array. The LED creates an infrared light beam that is focused onto the photosensor array and the output signal is then detected by the receiver. If an obstacle passes between the transmitter and the receiver, the infrared light beam is interrupted and this is detected by the photosensor array. This interruption is then converted into a logic-level signal or pulse by the receiver.

The OPB891L51Z is suitable for use in a variety of applications such as paper detection in printing and photocopying machines, door-open detection, and page turning systems. It is also suited for use in combination with counter modules. The OPB891L51Z also offers excellent timing accuracy and noise immunity which makes it ideal for sensing applications. Moreover, its extremely compact, lightweight design makes it suitable for use in confined spaces.

In summary, the OPB891L51Z is an optoelectronic Slot-Type Transistor Output Photointerrupter manufactured by Sharp. It is mainly used in sensing operations such as sensing of paper movement for photocopiers, documents, and other paper media. It has a transmitter and a receiver which are spaced apart through a measurable distance such as a groove or a slot. The operating principle is based on the use of light interruption to detect the supply or presence of an object being monitored, and its high accuracy, noise immunity, and compact design make it an ideal choice for sensing applications.
