Optical sensors are devices that are specifically designed to detect and measure the amount of light present in an environment.A Photointerrupter, also known as a slotted switch, is an optical sensor that is designed to detect interruptions in a light beam. The EE-SX398 Photointerrupter is a slot type Logic Output photodiode specifically designed to detect shadowing of a light beam from obstacles or protrusions entering or exiting a slot.

The EE-SX398 Photointerrupter is the ideal solution for applications where precise and reliable performance is required. This photointerrupter features a reverse connection guard pin for improved reliability in applications that handle reverse voltage. The EE-SX398 is available with either an NPN or PNP open collector output, making it suitable for a variety of switching applications in industries such as automotive, medical, and consumer electronics. This photointerrupter also features a low-current draw and a low operating voltage, making it well-suited for use in battery operated devices.

The EE-SX398 Photointerrupter is easy to install and integrates easily into a variety of applications. The slot size of 10mm x 110mm and the narrow waveform allow for precise placement of the sensing point. The tight slot also ensures that the sensing point is accurately triggered and gives optimum sensing precision.

The EE-SX398 Photointerrupter consists of a photo-emitter and a photodetector arranged for optical alignment in a slot form factor. The light emitter consists of a transparent plastic lens, an infrared light-emitting diode (LED), a polarization filter, and a light-receiving surface of the photo detector (photodiode).

When an object is placed in front of the EE-SX398, the light-emitting diode emits a beam of infrared light, which is characterized by its narrow waveform size, and a certain amount of this light is absorbed by objects passing through the sensing point. The intensity of the received light at the photodetector is compared with the intensity of the emitted light from the LED. When the intensity of the received light is lower than the intensity of the emitted light, the output signal is triggered and is outputted from the photointerrupter.

The EE-SX398 is designed to provide high speed, high accuracy, and a high signal-to-noise ratio. The photointerrupter offers a response time of less than 30 microseconds and a resolution of up to 1 micron. The EE-SX398 is also highly reliable, with a life expectancy of more than 1 million operations. The photointerrupter is also designed to be immune to electrical noise, making it ideal for use in locations where electrical noise is a potential issue.

The EE-SX398 Photointerrupter is a versatile solution for both industrial and consumer applications. The EE-SX398 is a waterproof unit, making it suitable for outdoor applications. It features a wide operating temperature range of -25°C to +70°C, allowing it to be used in a variety of environmental conditions. The EE-SX398 Photointerrupter is an energy-efficient and reliable solution for applications that require precise and reliable performance.
