The OPB618 is an optical sensor that is part of a family of components called Photointerrupters. These components act as digital switches, opening and closing a circuit as their output signal changes from low to high, or vice versa. As a slot-type optical sensor with a logic output, the OPB618 is well-suited for use in applications such as reading data in paper processing machines, object detection in factory automation, position detection in industrial processes, and motion control in medical equipment.

In a typical application, the OPB618 sensor is mounted on an actuating arm that moves in front of a printed circuit board. As the arm passes over the board, it blocks off a pair of light-emitting diodes (LEDs) and causes the output signal to become high. This signal can be read by a controlling computer or machine in order to bring about the desired outcome.

When considering the working principle of the OPB618, it is important to note that the light received in the sensor\'s input not only indicates the presence or absence of an object, but also the speed at which it is moving.By measuring the amount of ambient light reaching the sensor, the OPB618 can accurately detect objects and movements, even in situations where the ambient light levels are not constant.

The OPB618 is designed with robust optical components to guarantee consistent and accurate operation. For instance, the LED driver circuit is designed with noise-suppressing components to minimize the amount of noise that could distort the output signal. Meanwhile, the receiver has been designed to reject any ambient light that may be interfering with the signal.

The OPB618 also provides excellent durability for long-term operation. It is constructed from temperature-resistant materials and has an operating temperature range of -40°C to 85°C. It also utilizes advanced surface-mount design components to ensure reliable operation and mechanical stability, and the pin pitch is 0.7 mm, allowing for simplified and easy installation.

In addition to its exceptional reliability and durability, the OPB618 is especially economical. This makes it an ideal choice for applications that demand high performance but have tight budgets.

In summary, the OPB618 is a reliable, economical, and robust optical sensor that can be used for a variety of applications. Its logic output capability makes it a great choice for applications such as reading data in paper processing machines, object detection in factory automation, position detection in industrial processes, and motion control in medical equipment. The OPB618 has the capacity to provide extremely accurate and reliable results, and its robust design ensures its performance over long-term use.
