Optical sensors are used in a wide variety of industrial, medical, research and surveillance applications, and the E3T-SL11R is one example of a commonly used optical device for a variety of different tasks. Understanding the application field and working principle of this sensor can help to optimize its use in various contexts.

E3T-SL11R is a 2-wire AC type, NPN output, retro-reflective photoelectric sensor. It is designed for a wide operating temperature range, and a broad range of detection distances, with a sensing range of up to 2 m depending on reflector size and distance. Its detection principles are based on the retro-reflective system, where the device is comprised of a transmitting head and a receiving head, and when the reflected beam is blocked or distorted by an object placed in the area of detection, the output will be activated.

This device is suitable for a number of different applications, including the sensing of objects when checking an assembly line in a factory, safety checks, automated gate sensors, and limiting sensors for various industrial machinery. The detection system of the E3T-SL11R is also very reliable, and the device has several components to help maintain a consistent detection rate even when working in turbulent environments.

The most important component of the E3T-SL11R is the LED. This device comes equipped with an LED having an output power of 70 mW that helps to ensure highly reliable object detection and a stable response time. The LED is designed to work with either an AC or DC power supply, thus ensuring that the power source is universally compatible and suitable for most industrial applications. The E3T-SL11R also has a built-in amplifier that helps to increase the output power and reduce the noise to ensure a consistently reliable operation.

In addition to the LED, the device features a CMOS semiconductor integrated circuit that is designed to stabilize the sensitivity even under a variety of environmental and noise conditions. This ensures that the device can be used in areas with fluctuating temperatures, dust, and vibration, without any impact on its operation. The circuitry within the chip also provides a wide range of adjustable features, such as time delay, sensitivity, maximum input power, and more.

The E3T-SL11R can also be set up with an optional protective cover and rugged exterior, which helps to ensure the sensitivity even under hostile working environments. By selecting a cover or fitting that is compatible with the size of the environment, the device can provide reliable detection in environments that contain dust and other particulate matter.

The E3T-SL11R is a great choice for many industrial, research and surveillance applications. Its wide range of features and adjustable settings make it an ideal choice for applications where reliable sensing accuracy is essential, while its robust design ensures that it can operate without any degradation in performance in even the harshest of environments. Understanding the application field and working principle of this device can help to optimize its use in a variety of contexts.
