The E3S-BD81 is an optical sensor from the Omron Automation and Safety component family. It is an intelligent photoelectric device, designed for industrial automation applications and is designed with both infrared emission and infrared detection.

The physical form of the E3S-BD81 is a M18 cylindrical cast resin sensor with a polarization filter that is shielded by a stainless steel ring. It has two small electrodes positioned at the side of the device which are used to detect light. The device is powered by a DC voltage and requires a set amount of ambient light to function correctly.

The major feature of the E3S-BD81 is the ability to detect both reflective and transmissive materials accurately. This enables users to detect and classify objects of varying sizes and shapes without the need for manual alignment. The device also has a high speed response rate, making it suitable for use in high-speed applications.

The E3S-BD81 is designed to be used in a wide range of industrial applications. The principle of operation of the device is based on triangulation. It uses two light sources; an LED for emission and a photodiode for detection. The LED emits an infrared light signal which is modulated to create contrast. The photodiode detects the modulated light signal and determines direction and distance of the target object. The two signals are processed and compared to accurately calculate the distance and position of the target object.

The device is also capable of detecting small differences in light intensity, allowing it to measure light applied to the surface of an object. This is particularly useful when used in combination with other sensors in order to detect changes in the position of an object.

The E3S-BD81 is also capable of measuring the presence of a target object by sending out a continuous signal and detecting any changes. This is particularly useful in medical, food processing and automotive applications where the presence of an object must be monitored.

The device is also versatile and can be connected to other devices and controllers via popular communication protocols such as CAN Bus and RS485.

In conclusion, the E3S-BD81 is a versatile and efficient device suitable for a wide range of industrial applications. It is able to detect both reflective and transmissive objects, measure light intensity and detect changes in position. Additionally, the device is easy to configure and can be connected to other devices and controllers through popular communication protocols.
