The EE-SX298 optical sensor belongs to the Photointerrupters – Slot Type – Transistor Output category. It is an optical switch designed to detect the presence of narrow grooves or slits in a compact package. The EE-SX298 has a sensing range of 3mm and a hysteresis of 0.2mm. The EE-SX298 is a solid-state optical interrupter with a plastic molded case and a slotted diode. The device has a built-in LED light source and a photodetector, which are arranged to create an optical barrier that is broken when a groove or slit passes through the area between them. When no object passes between the emitter and the photodetector, the optical output of the device is ON. When something passes between the emitter and the photodetector, the optical output of the device is OFF. The EE-SX298 has a narrow detection range and a quick response time, enabling it to detect small objects even at high speeds. The EE-SX298 is used in a variety of applications due to its compact size and low cost. It is commonly used in industrial equipment to detect linear motion, such as conveyor belts or carriages, as well as robotic devices to sense the presence of specific objects. The EE-SX298 is also used for presence detection in consumer electronics, such as gaming consoles and other electronic devices. As the device is able to detect narrow slots and grooves, it is also used for presence detection in printing machines and barcode scanners. The working principle of the EE-SX298 is very simple. The device has an internal light source, which is directed toward a photodetector. The photodetector is sensitive to light, and when something passes between the light source and the photodetector, the output of the device changes from ON to OFF. The EE-SX298 is capable of detecting small objects even when they are moving at high speeds, making it very useful for a variety of applications.
