E2E-X2E15

Proximity Sensors are devices used to detect the presence of nearby objects without any physical contact. These sensors measure objects’ distance using electromagnetic or acoustic waves. The E2E-X2E15 is a Proximity Sensor from Omron, based on the non-contact detect distance (NCDD) method. It is used in electronic equipment such as car brakes, motor drives, and factory automation machines. This article will discuss the application field and working principle of the E2E-X2E15.

Applications of E2E-X2E15

The E2E-X2E15 is a general-purpose Proximity Sensor mainly used for detecting the presence of nearby objects or changes in object position when mounted onto an automated production line. It offers a wide detection range of 0.2 to 15mm. Additionally, the sensor can be used for functions such as measurement of gap distance in automatic clearing machines, positioning of rails in industrial equipment, and detection of paper jams in printing presses.

This Proximity Sensor is also used in high-speed automotive brake systems for sensing the lever position while moving around tight curves. Additionally, it can be used for detecting, controlling and monitoring motor speed variations, inserting items into holes, and detecting irregular surface patterns or uneven gaps in production assembly lines.

Working Principle of E2E-X2E15

The E2E-X2E15 is based on the Nondisruptive Contacted Distance Detect (NCDD) method which uses eddy currents to detect the presence and position of nearby ferromagnetic objects. A transmitting coil sends out a low-frequency alternating magnetic field.

When the Sensor detects a ferromagnetic object, the eddy currents that are generated cause a decrease in the transmitted magnitude of the alternating magnetic field. The Sensor then measures the decrease in the field and converts it to an electrical output signal proportionate to the distance of the object. This output signal can then be used to provide positional information.

The E2E-X2E15 utilizes a learning mode, allowing it to be adjusted to detect targets in all distances. The sensor can detect different objects sizes at different distances, and thus the learning mode allows users to adjust the sensitivity of the sensor to their desired level.

Additionally, for improved output accuracy, this Sensor comes with a manual reset button which can reset the built-in hysteresis to compensate for temperature drift of the sensing range. It also features two sets of LEDs which indicate indoor temperature from -10°C to 70°C.

Conclusion

The E2E-X2E15 is an important Proximity Sensor from Omron based on the NCDD method. It is suitable for a variety of applications such as automating production lines, detecting lever position in high-speed brake systems, measuring gap distance in clearance machines, and controlling and monitoring motor speed variations. The Sensor utilizes a learning mode to adjust its sensitivity for different targets, and features two sets of LEDs for temperature indication.
