Optical Sensors - Photointerrupters - Slot Type - Logic Output

The SF4-AH96 is a specialized optical device which uses light interruption detection to perform a number of specific sensing tasks. It operates as a general-purpose test and measurement instrument, however, it can be specifically tailored in accordance with a customer\'s specific requirements. This article will discuss the application field and working principle of the SF4-AH96.

Application Field of the SF4-AH96

The SF4-AH96 is a photointerrupter-type light interruption detection device which is used in numerous industrial, automotive, and home applications. It can be used in a variety of situations where precise timing and low power consumption is important. The photointerrupter-type optical device should be used as a detection device in open/closed loop measurement and test systems, adjusting speed of switches and motors, monitoring conveyor lines, determining position of elevators, and controlling door systems. Additionally, it can be used for precise 0.5Hz frame rate measurement, 1kHz frequency measurement of high speed optical pulse signals, and 0.25kHz frequency measurement of low speed optical pulse signals.  

The SF4-AH96 emits a visible red light during operation, allowing it to be easily visible in applications where environmental conditions are not ideal. This makes the device especially useful in common industrial applications involving humidity, dust, and heat. It also features a low-gain receiver, which helps reduce electromagnetic interference. This enhances the device\'s ability to accurately measure and detect light interruption signals in a wide variety of environments.

Working Principle of the SF4-AH96

The SF4-AH96 operates by detecting the interruption of an ambient light beam by the effects of a target object. The device consists of an emitter and a receiver. The emitter emits a visible red light beam, which is then broken by the target object, interrupting the beam and creating an interruption of light in the receiver. When this interruption of light has been detected, a logic signal is output by the receiver.

The logic output of the device can be either digital logic signals (high/low) or analog signals (voltages/currents). The SF4-AH96 also features adjustable time constants, allowing it to continuously monitor light interruption signals for long periods of time, reducing the need for frequent adjustments. Additionally, the device can function over a wide range of temperatures, allowing it to be used in a variety of environmental conditions.

The SF4-AH96 is a versatile light interruption detection device with a wide range of applications. Its low power consumption and wide operating temperature range make it ideal for industrial, automotive, and home applications. Additionally, the device\'s adjustable time constants allow it to continuously monitor light interruption signals, allowing it to provide precise measurements and signals in a wide variety of applications.
