The E3T-SL14 Photoelectric Sensor is part of the Optical Sensors product line. It uses a peripheral light-blocking design with a visible red sensing beam and a receiving photo transistor. This photoelectric sensor is used to detect surface features, usually placed near the target. It is designed for non-contact sensing and control applications, such as edge or color detection, and positioning, allowing a unit to read the signal when the sensing beam is interrupted.

Overview

The E3T-SL14 Photoelectric Sensor has a housing shaped like a cylinder with an operating voltage of 10 to 30 VDC, and a detection distance of up to 500mm depending on the environment. The size of the cylinder is 56mm in diameter, and the operating temperature range is 0 to 55°C. It also has a switching frequency of 0.5 to 2 kHz, and a response time of 15ms. This sensor can detect any object at a distance up to 500mm in different conditions, such as environment or reflectivity of material, without being distorted by external light sources. The light source and the receiver are in different parts on the sensor, allowing it to be highly accurate and precise.

Features

When the sensing beam is interrupted by an object, the transceiver sends a signal to the receiver that is relayed to the E3T-SL14 control unit. Depending on the installation angle, different signals are sent to different targets. This photoelectric sensor is also made of a durable and waterproof material, which helps to extend its service life and make it more suitable for harsh environments.

The E3T-SL14 is equipped with an Auxiliary output that makes the detection more reliable and the stable operation steady. It also has an adjustable sensitivity, allowing the sensor to differentiate between similar targets, and a built-in compensation for the sensor to both, offset and linearity with the target. It also has a built-in transistor circuit and the sensor is then energized by the control unit.

The E3T-SL14 Photoelectric Sensor is part of a broad range of industrial applications. It can be used in robotics, production line automation, electronic scales, paint lines, packaging, positioning, and more.

Working principle:

The working principle of the E3T-SL14 Photoelectric Sensor is based on the light reflection and absorbance principle. The light source is usually emitted from the optical transceiver. The emitted light is made of some infrared components, and the beam of light is projected to the receiver. The receiver then receives a signal and sends a signal back to the control unit.

When the sensing beam is interrupted by an object, part of the signal is absorbed by the target, and the rest is reflected in different directions. The receiver can then recognize the target, and relay the signal to the control unit. The control unit can then analyze the signal and decide whether the object is present or not. Depending on the target\'s reflectivity, the output signal will be more or less strong.

Conclusion

The E3T-SL14 Photoelectric Sensor is a useful and versatile device that can be used in a wide range of industrial applications. With its adjustable sensitivity and auxiliary output, it ensures reliable and accurate operation in harsh environments. Its advanced transceiver and receiver technology provide a fast response time and a detection distance of up to 500mm.
