Introduction

Optical sensors are sensors that convert light into electrical signals. They are broadly classified into three types: photoelectric, industrial, and fibre-optic. In order to demonstrate the use and working principle of a specific optical sensor, the E3F3-T11M 2M will be studied.

What is the E3F3-T11M 2M Optical Sensor?

The E3F3-T11M 2M is an optical sensor designed for industrial functions. It is capable of detecting very small objects of between 1 to 10mm, and is quite versatile, being able to be used with both DC and AC voltage. The sensor is also resistant to ambient light and can be used with a long range of materials, including metals, transparent objects, and dark coloured objects.

Application Field and Working Principle

The E3F3-T11M 2M optical sensor is most commonly used for automation equipment such as robots, disbursers, and control systems. It is also used to monitor object position, detect presence, and can be used to detect changes in humidity or temperature. The working principle of the E3F3-T11M 2M optical sensor is based on the principle of light transmittance. An infrared light source, usually an LED inside the optical sensor, projects a beam across the detection gap. If an object is detected between the gap, part of the beam is blocked. This is indicated by a voltage drop inside the sensor, which is then converted into an electrical signal representing the presence or absence of the object.

Advantages and Disadvantages

Optical sensors such as E3F3-T11M 2M have many advantages. They are easy to install and have a fast response time, as well as being reliable and offering a wide range of applications. Additionally, optical sensors are resistant to vibration and have a very low failure rate. The main disadvantage of the E3F3-T11M 2M is that it is not suitable for materials that strongly absorb near-infrared light, such as black and dark coloured materials. In addition, it has limited light transmittance, so it is not suitable for transparent objects.

Conclusion

The E3F3-T11M 2M optical sensor is a versatile industrial tool used for automation equipment and monitoring position, presence, and humidity and temperature changes. Its working principle is based on infrared light transmittance, making it fast and reliable. Its advantages include a wide range of applications and a fast response time, while its main disadvantages include a limited light transmittance and an inability to detect some materials.
