Optical Sensors are devices that utilize light to detect the presence or absence of objects. One of the most commonly used optical sensors is the Photointerrupter, which is designed to detect an object passing through a sensing slot, such as a slot in the wall or ceiling. Within this category of Photointerrupters, the Slot Type Transistor Output variety provides the highest range of sensing distances.

The OPB882L55Z is an example of a Slot Type Transistor Output Photointerrupter. This device consists of a sensor PCB (printed circuit board) with two slots for object detection, along with a light-emitting diode (LED) and photosensitive transistor. The OPB882L55Z also has an output terminal which can be connected to an IC or another control circuit device so that the sensor’s output signal can be monitored and a response can be issued when a certain action is detected.

The OPB882L55Z is generally used in applications such as object positioning and detection, object counting, and automation control. For example, in an industrial production setting, the OPB882L55Z can detect when an object passes through the sensors’ sensing slots, and trigger an action or provide feedback to a central control system. This device’s small size, low power consumption, and long sensing range make it especially suitable for applications in tight spaces and with minimal power.

The OPB882L55Z operates by utilizing optical signals to detect the interruption of light beam by passing objects. The sensor contains a LED and a photo-transistor which transform the incoming optical signals into electrical signals. As the object passes through the detection slots, the light beam is interrupted which causes the output state of the photo-transistor to change, triggering the output terminal to change its output state accordingly. This change in output state can then be detected by another circuit or system.

The sensitivity and sensing distance of the OPB882L55Z can be adjusted to suit different applications, such as long-distance sensing, high-precision applications, or high-speed applications. The sensing range can range from 5 mm to 5 cm, depending on the object’s size and its distance from the sensor. The switching frequency of the OPB882L55Z is typically around 100 kHz, and its response time can be as fast as 10 ns.

Overall, the OPB882L55Z is a reliable and cost-effective optical sensor that is well-suited to a variety of applications such as object counting, automation control, and object positioning. This device has an adjustable sensing range, switching frequency, and response time, and its low power consumption and small size make it ideal for use in space- and power-limited applications.
