Optical sensors, specifically photointerrupters, are devices that detect the presence of a target object when the light beam from the transmitter unit is blocked or interrupted. A type of photointerrupter is the slot type, like the EE-SX474, which has a logic output making its detection capabilities even more accurate and precise. This article will explain the application field and working principle of the EE-SX474.

The EE-SX474 is a slot type photointerrupter with a logic output which is widely used in automation systems, electronic devices, and many other applications. It is a compact, reliable, and cost effective solution for the accurate detection of objects that pass through a slot. This type of sensor can be used to detect the presence or absence of an object in a variety of applications, such as in paper manufacturing, conveyor systems, automobile sensors, and more.

The EE-SX474 features a built-in logic circuit that creates a logic output signal when the light beam from the transmitting unit is interrupted. This logic output signal is used to trigger an electrical signal for a specific application. The logic output signal can be configured to trigger a relay, a PLC, or any other electronic device. This type of photointerrupter is designed to be highly reliable with a wide operating temperature range and a low current consumption.

The EE-SX474 features a compact design and slim profile making it suitable for use in narrow and confined spaces. It is also highly resistant to environmental conditions such as dust, dirt, and humidity. The transmission range of the underlying light beam of the EE-SX474 is up to 70mm, and the supply voltage range is from 4.5V to 36V.

The working principle of the EE-SX474 is simple. When there is no object passing through the slot, the logic output remains low and nothing happens. When an object passes through the slot, the light beam is blocked and the logic output changes to true, triggering an electrical signal. The EE-SX474 comes with an LED indicator light that turns on when the logic output is in true state, showing that a signal has been triggered.

The EE-SX474 is a reliable and cost effective solution for many applications that require accurate object detection or logic signal triggering. It is a compact, slim design that is highly resistant to environmental conditions and produces a logic output signal when the light beam is blocked. This makes the EE-SX474 a great choice for many types of automated applications.
