OPB870N55

Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The OPB870N55 is a slot-type photointerruptor with transistor output. It is a solid-state optical switch with a light transmitting medium, such as an infrared LED, between the two optically connected slots. When an interruption is made between the two slots, the LED light is cut off and the output from the optoisolator switch is changed from an "off" to an "on" state. The OPB870N55 can be used in a variety of applications including sensing the presence of objects, control of machines and automated systems, and industrial safety control.

The working principle of the OPB870N55 photointerruptor is based on the principle of photoelectric effect. When a light source such as an infrared LED is placed in one end of the photointerruptor slot, the light travels through the optically aligned slot and is absorbed by the photodiode located at the other end. When an interruption is made between the two slots, the LED light is cut off and the output from the optical switch changes from an "off" to an "on" state. This change in output causes a voltage difference between the two terminals of the transistor, resulting in a switching action.

This application field of the OPB870N55 varies depending on the specific type of application. It can be used in sensing the presence of objects with speeds up to 2.5kHz, with an optical resolution of 1-3 mm and a switching time/delay time of 25/25 μs. In addition, it is ideal for control of machines and automated systems, as well as a variety of industrial safety control systems. It can also be used to detect small objects in automated sorting systems as well as to activate/deactivate safety features such as those on commercial parking lots.
