E2E/E2EQ NEXT Series Proximity Sensor

An extremely durable OMRON Proximity Sensors with an overwhelmingly long detection distance

We have created Proximity Sensors equipment that does not stop suddenly due to malfunctions or collisions!

With the world's longest detection distance of 7mm for M12, there is no collision with the OMRON Proximity Sensors, ensuring stable operation of your equipment!

Proximity Sensors E2E NEXT achieves a "long detection distance"! It contributes tothe realization of equipment that does not stop suddenly due to malfunction or collision .

Achieves approximately twice the distance of conventional OMRON Proximity Sensors

Detection errors with OMRON Proximity Sensors are unlikely to occur even if the dog separates due to device vibration.

Collisions with OMRON Proximity Sensors are unlikely to occur even if the workpiece seating position varies or is deflected.

The OMRON Proximity Sensors replacement time has been greatly reduced to approximately 10 seconds! No adjustments are required, so anyone can replace the parts in the same position.

OMRON Proximity Sensors Just insert and tighten!

The O-ring prevents foreign matter such as cutting oil from entering the e-jig, ensuring positioning accuracy (IP67G).

The OMRON Proximity Sensors Can be installed in existing facilities.

Even though the Proximity Sensors E2E NEXT is one size smaller, it has almost the same detection distance as conventional products (for M12, the detection distance is 7 mm, the same as the conventional M18).
By combining it with an e-jig, you can easily upgrade your existing equipment to one with a sensor replacement time of 10 seconds.

 

1. Remove the "M18" Proximity Sensors installed in the existing equipment.

 

2. Attach the "M18" size e-jig

 

3. Insert the "M12" E2E NEXT series into the e-jig

IP67G+ OMRON Proximity Sensors oil-resistant component evaluation standard provides oil resistance of 2 years!

The E2E NEXT (long distance type) e-jig has an IP67G rating to prevent the intrusion of foreign objects such as cutting oil and chips, andThe Proximity Sensors can be used in processing processes that use cutting oil.

The OMRON Proximity Sensors Also contributes to improved usability and freedom

The OMRON Proximity Sensors Can be installed without worrying about the direction of the indicator light

The OMRON Proximity Sensors Compact size improves facility design flexibility

By adopting the Proximity Sensors E2E NEXT (long distance type), you can contribute to equipment miniaturization in various ways while maintaining the same detection distance.Downsizing is possible
because the detection distance is approximately twice as long as conventional models.

OMRON Proximity Sensors Product development story

The development of the technology that forms the basis of the long-distance stable detection technology installed in E2E-NEXT began in 2000. The housing size of the OMRON Proximity Sensors is small, starting from a φ3 cylindrical shape,and the number of parts that can be mounted inside this housing is limited. The main circuit needs to be integrated using semiconductor process technology, so a custom IC is used.

Conventional custom ICs have been equipped with custom ICs composed of analog circuits.
However, the digital correction technology, which is an important element in realizing the long-distance stable detection that is the key to E2E-NEXT, has a large circuit scale and requires a fundamental review of the circuit design. Wedecided to use a digital-analog hybrid IC with a built-in digital circuit that can be finely wired. The feature of
this IC is that it can digitally control the oscillation amplitude of the Proximity Sensors and digitize and control the adjustment amount for each sensor.

The detection distance-temperature characteristics of the Proximity Sensors are affected by the temperature characteristics of the parts and the layout of the circuit, so optimization is required for each type.
In addition, the amount of correction for the detection distance depends on the shape and positional variation of the parts that make up the sensor, which causes variation.
Conventionally, this correction was adjusted in the intermediate process of production, but this is a major error factor.
Therefore, by using a unique communication method to write correction data for detection distance - temperature characteristics into the digital-analog hybrid IC, it became possible to carry out the correction at the final inspection. The

most difficult aspect of developing this digital-analog hybrid IC was that it was necessary to define all of the requirements and incorporate them into the IC specifications, even though these were taken for granted in conventional analogICs and specifications that were implicitly determined from past experience. Numerous problems occurred due to insufficient condition setting and incorporation into the specifications of Proximity Sensors, and there were many times whenthe schedule had to be readjusted.
However, by continuing the challenge without giving up, I believe we have achieved the world's longest detection distance* for a two-wire Proximity Sensors.
