Optical Sensors - Photointerrupters - Slot Type - Logic Output

SF4-AH36 is a slot type photointerrupter module from Vishay, a well-known global leader in the semiconductor and optoelectronic devices industry. It is designed for use in a range of applications, from electronic manufacturing and telecommunications to automotive and factory automation. This article will discuss the application field and working principle of SF4-AH36.The SF4-AH36 is a surface-mount photointerrupter module with a single-slot design. It has an operating temperature range of -40°C to +85°C and is rated at a maximum forward current of 40 mA. The module is composed of two components: an LED emitter and a detector. The LED emitter emits a light beam, which is then broken up into a series of small beams by the presence of a metal slot. When the slot is blocked, the light is reflected back to the detector, causing a change in the output signal.The SF4-AH36 is used in a variety of applications, ranging from factory automation to optical-to-electrical conversion. It is used to detect mechanical parts moving through a slot and as a position encoder in a variety of automation systems. It is also used in industry for counting and sorting applications, where it can detect the size and shape of an object passing through its slot. Additionally, it can act as a sensor for detecting and measuring the passage of liquids and gases.The working principle of SF4-AH36 is based on light-to-electric signals conversion. In this case, the LED emitter produces a beam of light that is blocked by the slot when an object passes through. The light is reflected back to the detector, producing a change in its output. The output from the detector is then converted into an electrical signal, which can be used for a variety of interfacing and monitoring purposes.The SF4-AH36 photointerrupter has a wide range of applications in a variety of industries. It can be used for precision sensing and positioning of mechanical parts, for automatic counting and sorting of objects, for light/dark triggering, and for optical-to-electrical conversion. In the industrial sector, the module is used for monitoring the speed of conveyor belts and for controlling the motor speed in machines and robotics. It is also used for positioning stages in factory automation applications.In conclusion, the SF4-AH36 is a slot-type photointerrupter with a wide range of applications. This module is capable of converting light into an electrical signal and is used in a variety of industries for sensing and positioning of mechanical parts, counting/sorting objects, and optical-to-electrical conversion. The SF4-AH36 is a reliable and versatile module, offering reliable performance in a wide range of applications.
