Optical Sensors - Photointerrupters - Slot Type - SF4-AH32-H Logic Output

Photointerrupters using logic output are electronic optical switches that utilize a specific type of optical sensing technology. This type of photointerrupter is composed of a light-emitting diode (LED) and a phototransistor connected in a Darlington configuration. This type of photointerrupter, known as the SF4-AH32-H, senses any object passing through the slot type between a light source and its detector.The SF4-AH32-H is a high-performance slot-type photointerrupter with a 0.5-mm slit width and operating voltage between 4.5 V and 30 V. As an information sensing device, the SF4-AH32-H utilizes optical sensing technology to detect and distinguish objects from various types of material such as plastics, paper, wood, metal, etc.The SF4-AH32-H features a one-touch mounting structure and a reliable, robust, and long-lasting design that allows it to operate in harsh environmental conditions. It is well-suited for various applications such as factories, elevators, security systems, robot arms, gaming machines, and medical instruments, to name a few.The SF4-AH32-H’s working principle relies on the object\'s interruption of light that passes between the SF4-AH32-H\'s LED light source and the phototransistor on the receiving side. When the LED light is interrupted when an object passes through the slit, the phototransistor transfers an electrical signal triggered by the SF4-AH32-H, which can then be interpreted as an electrical pulse equal to the number of objects passing through.The SF4-AH32-H features two types of outputation, normally open (N.O) meaning that current flows when there is light, and normally closed (N.C.) output stating that the device produces electricity when there is no light detected. As such, it is an ideal device for developing accurately countable systems as well as applications where speed and accuracy are paramount as the output signal remains the same and is unaffected by movement.In terms of its physical structure, the SF4-AH32-H measures 13.3 mm long, 14.6 mm wide, and has a standard pitch of 1 mm, making it suitable for printed circuit boards (PCBs) and standard electrical layouts. It is an environmentally friendly device since it is made using no pollutant materials; the main body is manufactured from flame-resistant, impact-resistant plastic and acrylics.The SF4-AH32-H is an ideal device for obtaining accurate counts of objects passing and for increasing the efficiency of any system that uses it. Its small and robust design makes it easy to install and integrate in applications making it extremely suitable for any kind of industry and automation project.
