Anti-spatter type proximity sensor E2EQ NEXT

Proximity Sensor That Is Hard to Break With Far Outperform Long Sensing Distance

Created an equipment that does not cause sudden stop due to malfunction or collision.

One of the World's Longest Sensing Distance, 7 mm With M12, Enables Stable Operation of Equipment Without Collision With Proximity Sensors.

E2E NEXT has achieved long sensing distance. It contributes to achievement of equipment that does not cause sudden stoppage due to malfunction or collision.

It Has Achieved Long-Distance Sensing That Is Approx. 2 Times That of Conventional Models

Even if the Dog Gets Away Due to Equipment Vibration, Sensing Errors Are Less Likely to Occur

Collision Is Less Likely to Occur Even if There Is Variation in the Mounting Position of the Workpiece or Deflection

The Replacement Time Is Greatly Reduced to Approx. 10 Seconds. Eliminating the Need for Adjustment Allows for Installation in the Same Position by Any Worker

The O-ring blocks contaminant such as cutting oil from entering the e-jig and secures positioning accuracy (IP67G)

It Can Be Installed in Existing Equipment

E2E NEXT provides nearly the same detection distance as the previous product even when downsized by one size (for M12, the detection distance is 7 mm, the same as the previous M18).
By combining it with the e-jig, you can easily upgrade existing equipment to allow sensor replacement in just 10 seconds.

 

1. Remove "M18" proximity sensor installed on existing equipment

 

2. Install "M18" size e-jig

 

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

2-Year Oil Resistance Based on IP67G + OMRON Oil Resistant Component Evaluation Standard.

E2E NEXT (long-distance type) e-jig prevents contaminant such as cutting oil and cutting chip from entering based on IP67G, and can be used in machining processes that use cutting oil.

It Contributes to Improving Usability and Flexibility

It Can Be Installed Without Worrying About the Direction of the Indicator Light

Increased Flexibility in Equipment Design by Downsizing

Adoption of E2E NEXT (long-distance type) contributes to downsizing of equipment from various points of view while maintaining the sensing distance.
Downsizing is possible because the sensing distance is approx. 2 times that of conventional models.

Behind the Scenes of Product Development

Technology development started in 2000, which is the basis of the long-distance stable sensing technology installed in E2E-NEXT. The proximity sensor housing with as small as ⌀3 cylindrical shape is available as one of the smallest, for which the parts that can be mounted inside the housing are limited, and the main circuit needs to be integrated using semiconductor process technology. Accordingly custom ICs are used.

Custom ICs composed of analog circuits have been equipped, for conventional models.
The digital correction technology, which is an important factor to achieve long-distance stable sensing which is the key to E2E-NEXT, has a large circuit scale and requires a fundamental review of the circuit design. Accordingly the manufacture decided to adopt a digital-analog hybrid IC with a built-in digital circuit that allows for micro wiring.
The feature of this IC is that the oscillation amplitude of the proximity sensor can be digitally controlled and the adjustment amount for each sensor can be quantified and controlled.

The sensing distance-temperature characteristics of the proximity sensor are affected by the temperature characteristics of the parts and the layout of the circuit, so optimization is required for each model.
In addition, the correction amount of the sensing distance depends on the shape and position variation of the parts that make up the sensor, and the variation occurs.
In the past, this correction was adjusted in the intermediate process of production, but this was a large error factor.
Therefore, by writing the correction data of the sensing distance-temperature characteristics to the digital-to-analog hybrid IC using the manufacture's own communication means, the manufacture has achieved to perform correction in the final testing.

One of the most difficult point in the development of this digital-to-analog hybrid IC is that it was necessary to define all the requirements and incorporate them as IC specifications, even for the specifications that were implicitly determined from the conditions that were obvious for conventional analog ICs and past experience. For points that were insufficient in terms of the condition setting and incorporation into the specifications, it was often necessary to readjust the schedule due to many problems occurred.
By meeting the challenges without giving up, the manufacture has achieved one of the world's longest sensing distance* with a 2-wire proximity sensor.
