The E3S-AD21 Photoelectric Sensor is a multi-dimensional photoelectric sensor that combines analog and digital technology. It provides a wider sensing distance and a more accurate sensing range than conventional analog models. It offers the combined benefit of increased resolution for better accuracy and is suitable for most industrial applications.

The E3S-AD21 is a light sensing device that detects changes in light intensity caused by an object passing through the sensing field. The Photoelectric Sensor uses its onboard amplifier to convert the signal received to digital output. It can be used to measure distance, speed, movement, or the reflectivity of an object. Additionally, this sensor can be used to detect very small objects or materials in high-precision applications.

The E3S-AD21 consists of a light source and a photoelectric detector. The light source emits a light beam which is then reflected off an object, or reflected off an object’s surface and then detected by the sensor. Depending on the configuration, the light source could be a LED or a laser diode. The laser diode is much more sensitive and has a greater sensing range.

The Photoelectric Sensor will detect changes in light intensity and its associated output signal will represent those changes. The output voltage can be used to control and monitor industrial equipment, or to provide feedback necessary for automatic process control. The output signal is processed either through an analog-to-digital converter (ADC) or digitally processed.

The E3S-AD21 has a compact form factor and is available in both AC and DC configurations. It is suitable for highly accurate and precise environmental control applications in industrial settings. The E3S-AD21 features high resolution, wide areas of detection and excellent repeatability. It is also resistant to interference from external electromagnetic fields, making it ideal for use in rugged and hazardous environments.

The E3S-AD21 utilizes an array of optical field detectors, allowing for the sensing of different light intensities. This is accomplished by the dual-emitter array, which is composed of two identical emitters. Each emitter transmits a light beam in two directions, and the two beams coming from the emitters overlap each other at a certain location. This allows the photoelectric cell to detect changes in the light intensity as the object passes through the overlapping beams.

When the object is detected, the signal sent to the amplifier will be amplified and converted to a digital format. The digital signal is then sent to a processor for further processing. The processor is responsible for analyzing the data and taking the appropriate action based on the associated program.

The E3S-AD21 is a reliable and cost-effective solution for industrial automation applications. Its advantages include high resolution, wide sensing range, interference resistance, and a simple installation process. Additionally, it provides significant savings in time and money compared to other sensing devices. Its small size, dependability, and robust design make it suitable for complex machine vision system applications.
