Optical Sensors - Photointerrupters - Slot Type - Logic Output

The OPB983N55 is an opto-interruptor type slot photo sensor which operates with a sensing distance of 5.5mm, an operating voltage of 5V and maximum current of 2.5 mA. It is a small, surface mount device which requires minimal space for installation and can be used in a wide variety of applications. The OPB983N55 has a single output that is pulse modulated in order to achieve higher levels of signal integrity and accuracy.

The main application for the OPB983N55 is in proximity sensing. This is achieved through the detection of objects and obstacles that are placed near it. For example, it could be used in a vending machine to detect coins and other objects that are placed within the machine. It could also be used to detect objects in an industrial setting such as in conveyor belts or robotic arms. In addition, it can be used in safety applications like machine warning systems.

Working Principle

The OPB983N55 uses an infrared LED and an infrared phototransistor. The light emitted from the LED is broken up by obstacles and this change in light intensity is then detected by the phototransistor. This is then converted into electrical signals which can be used by external circuits or logic circuitry. The operation of the device is that when no obstacles are present in the sensing range, the LED will be continuously lit which will cause the phototransistor to output a high signal level. When an obstacle is placed within the sensing range, the LED will be blocked and the phototransistor will output a low signal level.

The OPB983N55 has several features that make it suitable for various applications. These include an adjustable sensitivity, a pulse modulation and a long sensing range. The adjustable sensitivity feature allows for the distance between the LED and the phototransistor to be adjusted according to the requirements of the application, while the pulse modulation ensures high levels of signal integrity and accuracy. The long sensing range of 5.5mm helps to increase the device’s efficiency and the reliability of its detection.

The OPB983N55 is a versatile and dependable device which is suitable for many different applications. It can be used in industrial settings, vending machines, safety systems, proximity sensing and more. Its features make it an ideal choice for applications that require a reliable and accurate sensor that requires minimal space for installation.
