Optical Sensors - Photointerrupters - Slot Type - Transistor Output are ideal for non-contact detection of objects passing through a slot. The OPB842L51 is a particularly popular device in this area due to its dual-transistor output, precision in identification of objects, and its general ease of use. It can reliably detect most objects of the same size or greater passing across the photointerrupter\'s slot.

To understand the OPB842L51\'s photointerrupter technology, we first must look at the inner workings of the device. The OPB842L51 is an optical fining-type photointerrupter, which consists of an infrared emitting diode (IRED) and a phototransistor mounted on opposite sides of a plastic housing. When the light emitted by the IRED hits the surface of a passing object, the phototransistor detects a change in the light level and output a signal (ON/OFF) indicating the presence of the object.

There are a variety of applications that the OPB841L51 finds useful for. These include detection of printed characters or other printed graphics in printing presses, detection of paper passes, determination of parts position in machines, detection of damaged products, and many more. It is also widely used in home and industrial automation like in the automatic doors equipped with an array of these sensors, ensuring their safe operation.

The convenience and reliability of the OPB842L51 makes it an excellent choice for applications requiring detection of objects passing through its slot. An additional benefit of the OPB842L51 is its wide range of applications. Its simple design and single-transistor output make it suitable for a variety applications requiring object detection. In addition, its dual-transistor output makes it particularly well suited for applications that require precise identification of objects.

The OPB842L51 is also versatile and can be used in a variety of settings and environments. The range of switching voltage is between 2 volts and 25 volts and the range of source voltage is between 10 volts and 30 volts. This gives the OPB842L51 the capability to be used in a wide variety of applications, and these ratings make the device more durable, which means it will last longer than its competitors.

Overall, the OPB842L51 is an ideal choice for applications requiring an accurate, easy to use, and reliable photointerrupter. Its dual-transistor output combines precision identification with the wide range of available applications. As such, the OPB842L51 is a great choice for many different applications.
