OPB882T55

Optical sensors, such as photointerrupters, slot type, transistor output, are used to detect presence or absence of an object within a given area. The OPB882T55 is an ideal sensor for this application. It has a compact design with a small mounting area that makes it perfect for many applications where size is a factor. Additionally, it is a high-speed device, which means it can detect even the quickest of moving objects.

The OPB882T55 has an NPN output transistor that is characterized by an operating voltage range of 4.5V to 18V. This transistor features a maximum collector current rating of 300 mA, a 1.0 mA typical base current when fully open, and a 2.0mA typical base current when fully closed. This transistor also has a saturated collector-emitter voltage drop from 10V to 0.35V.

The working principle of the OPB882T55 is quite simple. When an object passes through the slot, the output transistor turns on, activating the output signal. This signal can then be used by the device to detect the presence or absence of the object. Furthermore, the output transistor can be used to control other circuits or devices, allowing for further customization of the sensor.

The OPB882T55 application field is extremely broad. It is commonly used for detection and automation in applications such as: printing presses, packaging machines, industrial automation, surface thickness inspection, textile weaving, and even vehicle guidance. Furthermore, its small size, long life, and high-speed operation make it suitable for mobile robotic applications, as well.
