Optical sensors are key components of modern industrial equipment, providing feedback on a wide range of variables such as position, temperature, pressure or speed. The E3RA-TP21 is an Optical Sensor in the Photoelectric, Industrial category, used to measure distances, levels and angles.

The E3RA-TP21 is a compact photoelectric displacement sensor with a built-in amplifier for high level output. It has a 0 to 30mm measuring range with a 0.05mm resolution, making it ideal for applications where space is limited or stringent accuracy requirements must be met. It is also designed to handle high temperatures of up to 120 C, making it suitable for many tough industrial environments.

The E3RA-TP21 uses a combination of phototransistors and fiberoptic cables to measure displacements. The signal is generated by a light beam transmitted from an LED in the sensor, travelling along the fiberoptic cable. When the beam reaches the end of the cable, it is detected by a phototransistor, sending a signal back to the sensor. This signal is then amplified and outputted as an analog voltage.

This technology is used in many industrial applications. It is often used in the automation and robotics industry to measure accurate distances for positioning and control. It is also commonly used in materials handling systems as part of a level sensing system to detect when a load is over a certain height. It can also be used to detect changes in angle, such as platform tilt.

The E3RA-TP21 is an ideal choice for these applications, as its small size and high accuracy make it easy to integrate into existing systems. It is also resistant to high temperatures and can handle a wide range of signal levels, making it suitable for a variety of industrial settings.

In addition to its industrial applications, the E3RA-TP21 can also be used in non-industrial settings for scientific or research purposes. For example, it can be used in experiments to measure and analyze small changes in distances or angles over time. It can also be used as part of a set-up to measure the refractive index of a medium, such as air or water.

The E3RA-TP21 optical displacement sensor is a versatile and reliable tool for measuring distances, levels and angles in a range of applications. Its compact design and high-accuracy make it perfect for precision work, and its resistance to high temperatures make it suitable for many different industrial settings.
