Optical Sensors are widely used in all kinds of industrial and consumer applications such as automations, home appliances, medical devices, and even security systems. Photointerrupters, or slot type optical sensors, are an example of such an optical sensor. OPB890L51Z is a Photointerrupter-Slot Type-Transistor Output specifically designed for application in industrial automation and medical device.

The OPB890L51Z is a compact and light-weight device of which the body size is only 6. 9 × 15. 9 × 7. 6mm. It consists of an infrared emitter and a receiver which are placed opposite from each other. This photointerrupter is especially suitable for detecting objects that pass through the gap between the emitter and receiver. When an object passes by, the emitted light from the infrared emitter is interrupted and the receiver measures the light intensity, which is then emphasized as output signel by the signal processor in the Photointerrupter.

The output of OPB890L95Z is in form of a transistor signal. When the emitter emits infrared light, the transistor output is "low", and when no light is present, the transistor is in "high" state. This high/low level digital signal makes it easy for usage with other MCUs and other devices on the board. The OPB890L51Z is also equipped with an optical filter to prevent unwanted light sources from intruding the signal and causing false signals.

In terms of applications, the OPB890L51Z Photointerrupter-Slot Type-Transistor Output is mainly used for applications involving object detection. This can be applied in industrial automation, where it can be used to detect objects moving along a conveyer belt. The photointerrupter is also suitable for detecting the presence of an object within a certain range. This can be applied in medical applications like sleep analysis devices or glucose meters, where it can be used to detect the presence of the user.

Photointerruptors like the OPB890L51Z are also capable of displaying pulse widths and frequencies. This offers various possibilities when applications who require object detection, pulse width or frequency detection are needed.

To summarize, the OPB890L51Z is a compact and efficient Photointerrupter-Slot Type-Transistor Output suitable for various applications such as industrial automation, medical device and sleep analysis. It is capable of detecting objects passing through, or within a range, and also displaying pulse widths and frequencies. Its small size and light weight allows it to be integrated to various devices, making it suitable for compact designs.
