Optical Sensors - Photointerrupters - Slot Type - Logic Output Optical Sensors compose a diverse family of components used to detect light. A common family member is the Photointerrupter, a device which utilizes a light source placed between two sensors in order to determine the presence or absence of a product, person, or animal in a given area. In addition to the traditional slot type photointerrupters, there are more advanced Photointerrupters available with logic output capabilities, a feature which has made them increasingly popular in a variety of applications. This article will discuss one such device, the OPB930W55 Photointerrupter, and explore its applications and common working principle.

The OPB930W55 Photointerrupter is an IRC device, meaning the device contains two photo detectors and an infrared LED light source which works together to detect movement. When an object passes through the slot, the light is being interrupted, causing electrical pulses sent to a connected controller. This type of photointerrupter has become increasingly popular due to its ability to detect objects from 0.6mm up to 15mm, making it suitable for applications with smaller products. The OPB930W55 operates at an output current of 50mA, operating voltage of 4.5V to 30V DC, and features a wide operating temperature range of -40 to +125°C.

The OPB930W55 Photointerrupter has a variety of applications within the industrial automation sector such as machine tools, Automatic Guided Vehicles (AGVs), conveyors, door automation, and packaging machines. Its high detection accuracy and low cost makes it a great choice for these types of applications. Its logic output function also makes it suitable for in-line production process applications, including counting the number of packages passing through a conveyor. All these applications require the use of an object being detected, whether it be a product, person, or animal.

The common working principle of a photointerrupter involves the use of an infrared LED light source placed in between two sensors. When a product, person, or animal passes through the slot, the light is blocked, sending an electrical pulse which is then received by the controller. This signal is then used to activate numerous functions, such as controlling motor speed or starting and stopping devices.

In conclusion, the OPB930W55 Photointerrupter is an example of an advanced photointerrupter with logic output capabilities. It features a wide operating temperature range, a high detection accuracy, and a low cost making it a top choice for industrial automation applications. Furthermore, its common working principle requires the use of a light source placed in between two sensors, allowing it to detect the passage of products, persons, and animals with ease.
