E3S-R2E41

Optical sensors are devices capable of detecting and measuring visible or invisible light. Optical sensing technology is employed in myriad applications across industrial, environmental, medical and consumer sectors. From highly automated factory environments to remote monitoring of weather conditions, optical sensors play a mission-critical role in modern automation technology.

The E3S-R2E41 light-based sensing device is a state-of-the-art optical sensor designed for industrial applications. It is a 2-wire DC optical sensor with a built-in feedback system, meaning it can both detect and identify light sources of various wavelengths and intensities. The sensor is used in a variety of applications such as detection of moving objects, door/window locks, and environmental monitoring.

The E3S-R2E41 operates on the principle of photoelectric effect. This is an optical sensing process that takes advantage of light absorption to measure an object’s position, size, or distance. The photoelectric effect is based on the absorption of certain wavelengths of light by an object. When the light that strikes the object is within the range of the wavelengths that the object absorbs, it will be converted into electrical energy.

The E3S-R2E41 is composed of two components: an LED and a light receiver. The LED emits visible light with a specific wavelength and intensity; the light receiver is made up of a photodiode and an amplifier. When light from the LED strikes the receiver, a current is generated, and this triggers the amplifier to generate a feedback signal. This signal is then amplified further, giving the user the ability to detect the presence and/or absence of an object, based on the strength of the resulting signal.

The E3S-R2E41 is widely used in industrial applications where reliable light-based sensing is required. For example, it can be used for detecting movement via its ability to detect changing light intensity. The sensor can also be used for door/window locks, environmental monitoring, and determining the presence of a solid object. Its versatility makes it one of the most widely used light-based sensors in the industrial market.

The E3S-R2E41 is a reliable, cost-effective and easy to use light-based sensing device. With its ability to detect and identify various light sources, the device has become an essential component of industrial automation technology. Its versatility and accuracy ensure that it will continue to be a mainstay in industrial, environmental, medical, and consumer applications.
