Optical Sensors - Photointerrupters - Slot Type - Transistor Output

Photointerrupter type optical sensors are used for a variety of applications, ranging from basic sensing applications such as presence detection to more advanced detection systems used in robotics, automated industrial processes and other industrial applications. Photointerrupters are one of the most common optical sensors, and are typically composed of an infrared emitter-detector pair divided by an opaque barrier. The OPB842W55Z is a slot type photointerrupter with a transistor output. It is a fully integrated optical sensor that combines a gallium arsenide infrared (GaAsIR) LED and an integrated circuit (IC) in a single unit, providing reliable operation over a wide range of operating temperatures.

The OPB842W55Z is equipped with a unique output stage which uses an insulated output transistor. This allows for longer pulse widths, higher reliability, and a higher-quality output signal. The OPB842W55Z can detect objects between 0.1 and 2mm in size, which makes it an ideal choice for presence detection and other detection applications. The OPB842W55Z also features a low current consumption, fast response time, stable optical output, and low noise operation. It operates over a wide operating temperature range, from -20°C to +85°C.

The working principle of the OPB842W55Z is relatively straightforward. An infrared LED emits an infrared light beam towards an object that needs to be sensed. When the infrared beam is blocked or disrupted, the detector detects the absence of the infrared light and produced an electrical signal. This signal is then transferred to an output stage, which can be connected to external circuitry for further processing. The output stage uses an insulated output transistor to produce a high-quality output signal.

The OPB842W55Z is widely used in industrial automation and other high-level sensing applications. Some of the most common uses of this photointerrupter include the detection of objects, presence detection, and distance measurement. In automation systems, it often serves as an essential component in identifying the location and size of objects or obstacles. Additionally, it is also used in systems which require accurate measurement of distances at very small scales.

Overall, the OPB842W55Z slot type photointerrupter with transistor output is a powerful and reliable optical sensor that can be used in a variety of applications in the industrial, automotive, and medical fields. The unique output stage provides a higher-quality output signal than conventional photointerrupters, while the wide operating temperature range and low current consumption ensures reliable and stable operation in all conditions. With its high level of accuracy and ease of integration into existing systems, the OPB842W55Z is an ideal choice for a variety of sensing and detection applications.
