Optical sensors are electronic devices that use a light source to detect the presence of an object. One of the most common and widely used optical sensor types is the photointerrupter. Photointerrupters are often used to detect the presence of an object in a certain area or to measure the relative position of objects inside a machine.

OPB828C is a type of photointerrupter specifically designed for applications requiring a slot-type photointerrupter with transistor output. The OPB828C is a two-channel photointerrupter, meaning it is composed of an LED and a phototransistor. The LED emits a light beam that is then sensed by the phototransistor, which then generates the output signal when it is interrupted. The LED and phototransistor are mounted in a single housing, and the output signal is a logic level transistor. This makes the OPB828C ideal for use in applications needing fast switching speed, high reliability, and low power consumption.

The OPB828C is designed for applications involving the detection of the presence of objects in small spaces. This could include a wide range of uses such as sensing the presence of an object, controlling the movement of a robotic arm, or providing positional feedback for automated machining tools. The accuracy of the OPB828C is improved by the fact that the sensing elements (LED and phototransistor) have a narrow range of angular accuracy. This ensures reliable detection and measurement regardless of the orientation of the object being detected.

The OPB828C also has several other advantages compared to other types of photointerrupters. The detection range of the OPB828C is up to 10mm, and the response speed is approximately 10µs. This means the OPB828C can provide fast switching speed for demanding applications. The OPB828C also has low power consumption, as it only requires 6mA during operation and 0.3mA during standby. This makes it ideal for applications that need to operate for extended periods of time without consuming high amounts of power.

The OPB828C is designed for use in a wide range of applications, from sensing the presence of objects to providing positional feedback for sensitive machinery. With its high accuracy and fast switching speed, the OPB828C is an ideal choice for many different applications requiring precise optical sensing solutions.
