EE-SX493: Optical Sensors - Photointerrupters - Slot Type - Logic Output

The EE-SX493 is a type of optical sensor that uses photo interrupters to detect slot type objects, with logic output. It is designed to provide reliable functionality in small spaces, making it suitable for use in various industrial and electronic applications.

Application Field

The EE-SX493 photointerrupter can be used in a variety of industries and applications, such as in motor control, process control, and machine vision systems. It is well-suited for applications requiring precise position and speed control, such as with motor encoders, shafts, and spindles.

It can also be used in robotics applications, as well as in medical systems, cell-phone keypads, gaming devices, and more. Additionally, it can be used to detect the presence of items on a conveyor belt or detect the presence of components in assembly lines.

Working Principle

An EE-SX493 photointerrupter works by sending pulses of light across a gap in an object. When a gap is detected, the light is blocked and recognized by the photointerrupter. This blocks the current flowing through the device, and the output signal is changed from low to high, or vice versa.

The EE-SX493 uses an encoder wheel to detect the presence of slotted objects. The encoder wheel is mounted on the rotating shaft. As the wheel rotates, the slots pass through the gap between the photointerrupter’s emitter and receiver. As the slots pass, they cause a low-to-high (or vice versa) transition in the output signal.

The EE-SX493 uses a logic output to provide a low or high voltage signal, depending on the presence or absence of a slotted object. This output can be used to drive logic circuits, such as counters, timers, and positioners. Alternatively, this output can be used to activate relays, motors, solenoids, and more.

The EE-SX493 is designed to meet the EMC standard EN 50082-2, making it suitable for industrial applications where electromagnetic interference is present. Additionally, the device has reverse protection and an operating temperature range of -25°C to 85°C.

The EE-SX493 is a practical and reliable solution for applications that require precise detection of slotted objects. By using optical sensors and logic outputs, it is able to provide reliable and accurate results in a variety of applications.
