Optical sensors are devices that detect the presence of an object or a change in a physical property such as light. Photointerrupters are a type of optical sensor that uses an optical source and a photosensor to detect the interruption of light between them. The SF4-AH72-N is a slot type photointerrupter which has a logic output, making it especially useful in applications where high speed, reliability and accuracy are paramount.

The SF4-AH72-N is a small-sized, board-mounted photointerrupter with a slot width of 0.3 mm. The light emitting diode (LED) light source is contained within the package, and the output pin is connected to a hidden photosensor within the package which is used to detect the interruption of light.

The main goal of the SF4-AH72-N is to detect the presence, absence, or change in the presence of an object, such as monitoring the motion of a roller or detecting an index plate. When light is interrupted by an object, the photosensor within the SF4-AH72-N detects this interruption and the output is set to a low state. When the object is removed and the light is no longer interrupted, the output is set to a high state.

The SF4-AH72-N is designed to operate in temperatures from -40 to +85°C, making it suitable for a variety of environmental conditions, and can operate at a frequency of up to 15 MHz. It features a sensitive gate length of 0.2 μm and provides excellent noise reduction performance. It is also RoHS compliant, meaning it meets the standards set forth by the United States Environmental Protection Agency.

The SF4-AH72-N is an ideal solution for applications that require high speed, accuracy and reliability. It is often used in automated control systems, monitoring systems, and factory automation equipment, and can be used to detect objects such as index plates, micro switches, and rotary/linear sliders. Other applications include material handling and sorting systems, motion control systems, security equipment, and other equipment where the presence or absence of objects needs to be quickly and accurately detected.

In conclusion, the SF4-AH72-N is a versatile, high-speed, and reliable slot-type photointerrupter with a logic output. It is designed for use in a wide range of applications that require quick and accurate detection of the presence or absence of an object. Its ability to operate in a variety of environmental conditions and its RoHS compliance make it an ideal solution for factory automation and other industrial applications.
