OPB360T51 Application Field and Working Principle

The OPB360T51 optical sensor, also known as a Photointerrupter, is a special type of optical sensor that uses the interruption of light in a sensing region as its main detection principle. It is designed for applications that require high-speed switching with low power consumption. The OPB360T51 is part of the Slot Type Transistor Output series of optical sensors and is a compact, surface-mount package that is easily integrated into a wide range of applications.

Description

Optical sensors are electronic devices used to detect the presence or absence of some type of light. The Photointerrupter is a type that utilizes an optically blocked beam as its main detection principle. The OPB360T51 optical sensor is a form of Photointerrupter featuring a narrow, linear slot between the emitter and receiver elements. This slot type sensor provides fast and stable switching operations similar to mechanical switches or integrated relays while having low power consumption and consistent performance over time.

Features

The OPB360T51 has a built-in suppressing circuit which eliminates any erroneous switchings caused by light reflection and optical crosstalk noise. Its operating current range is wide and it can be applied to both digital and analog systems. It has a wide response range from visible to infrared light, and a wide response angle. Its sensitivity can be adjusted using the precision screw on the side and the maximum sensitivity can be much higher than other optical sensors. It also has a voltage-output transistor type output which makes it suitable for applications requiring a high-speed response.

Applications

The OPB360T51 optical sensor is ideal for use in a variety of applications due to its compact size, high output power, and wide triggering angle. Common applications include detecting presence or absence of objects in consumer and industrial automation systems, robotics, machine vision systems, printer paper feeders, optical switches, and other systems requiring reliable detection of materials.

Working Principle

The OPB360T51 optical sensor utilizes an optically blocked beam between the emitter and receiver elements for its main detection principle. An infrared LED is used to emit light into the linear slot located between the two elements. When an object passes through this slot, the emitted light is blocked and the receiver element no longer detects the beam, triggering the sensor output and producing a low voltage. Conversely, when no object is present, the emitted light is then detected by the receiver element and the output voltage remains high.

Conclusion

The OPB360T51 optical sensor is a compact and reliable Photointerrupter designed for use in a wide variety of applications. It offers high-speed switching with low power consumption and features a built-in suppressing circuit for added protection. Its wide response range and adjustable sensitivity make it a great choice for use in consumer and industrial automation systems, robotics, machine vision systems, optical switches, and other applications requiring reliable detection of materials.
