Proximity Sensor


Enables easier and standardized designs previously not possible. IO-Link as a standard feature

Easy design

Equipped with exceptional sensing range*1 to enable collision-free sensor installation

Enables designs with more distance between the sensor and the sensing object, thereby reducing unexpected facility stoppages due to collision and false detection, which occurred with previous proximity sensors.
*1. Based on August 2022 OMRON investigation.

Allows for more spacious design with less risk of contact

With previous models, to avoid false detections, you were forced to adopt sensor installation designs that risked contact. The E2E NEXT PREMIUM Proximity Sensor can detect accurately from a greater distance, which means you can adopt designs with more space and less risk of contact.

E2E NEXT Features 3

Less false detection even when a stationary gets away from the sensor due to equipment vibration

E2E NEXT Features 4

PROX3 hybrid circuitry with Thermal Distance Control 2 eliminates ambient temperature influence to enable extended sensing ranges.

Proximity sensors with longer sensing distance require increased sensitivity. However, with the increased sensitivity, temperature changes will have bigger influence in sensing distance, and differences between individual sensors will be bigger. E2E NEXT Proximity Sensors (3-wire models) solve these issues by newly implementing Thermal Distance Control 2, a technology to enable extended sensing ranges. It enables in-line measurements of each sensor’s temperature characteristics, using multiple temperature points, in IoT-enabled production processes. The optimal correction values are then calculated based on our unique algorithm. The values are written into the analog digital hybrid IC (PROX3) for shipping to minimize differences between sensors and the influence of temperature changes that may occur in the customer’s environments.

E2E NEXT Features 7

Standardized design [PREMIUM Model]

Exceptional sensing range*1 allows you to standardize your design with a single one-size model

Ensures equivalent sensing distance while being one size smaller than previous models. Equipment and facilities formerly designed to use sensors of multiple sizes can now be designed to use sensors that are all the same size, allowing you to standardize your designs.

E2E NEXT Features 9

Easy to install, even where space is limited

E2E NEXT PREMIUM Model Proximity Sensors ensure equivalent sensing distance while being one size smaller than previous models, allowing you to install them in spaces where conventional sensors were too big to fit.

E2E NEXT Features 11

Note: When installing proximity sensors, make sure to factor the influence of surrounding metal into your designs.
(Refer to Influence of Surrounding Metal upon Design on Catalog for details.)

One size smaller than previous models

Size comparisons between models with equivalent sensing distance (“E2E NEXT” refers to quadruple distance models)

E2E NEXT Features 12

Unifying the model types to reduce the number of parts kept in inventory.

E2E NEXT Features 13

New standards for usability Early error detection [PREMIUM Model] [BASIC Model]

Enables facility designs that allow for early discovery of the site and substance of failure

Less time required from failure to recovery (MTTR: Mean Time To Recovery).

Enables real-time identification of the site and substance of sensor failure from a single location

By using the IO-Link Master to connect proximity sensors to your controller, you can use your monitor (HMI) for early discovery of the site and substance of proximity sensor failures.

E2E NEXT Features 16

Enables predictive maintenance through condition monitoring

Connecting sensors with controllers using IO-Link Master enables to send information necessary for stable operation to host devices. This enables condition monitoring and failure detection of sensors, which in turn contribute to predictive maintenance of equipment and facilities. You can also increase the productivity of your facility by accumulating information in databases and feeding analysis results back to equipment on the site.

E2E NEXT Features 17

New standards for usability Quick recovery [PREMIUM Model] [BASIC Model]

* Applies only to the description of the high-brightness LED indicator.

Enables facility designs that allow for quick recovery in case of failure

Less time required from failure to recovery (MTTR: Mean Time To Recovery).

All around visible high-brightness LED indicator

Adopts high-brightness LED that is more luminous and visible than those in previous models. The indicator is visible from all angles, reducing the time required for operation checks after sensor replacement.

E2E NEXT Features 20

Replacements in as little as 10 seconds*1 using e-jig

Using e-jig eliminates the need for adjustment so that anyone can install in the same position.

E2E NEXT Features 21

Easily upgrade existing facilities to enable “10-second* proximity sensor replacements”

The HIGH SPEC Model’s sensing distance is approximately twice that of previous models. For example, the sensing distance of the quadruple distance model of M12 sized is 9 mm, which is about the same as conventional M18 models. Using these sensors together with the e-jig allows you to easily upgrade your existing facilities so that you can replace their sensors in just 10 seconds.*1

E2E NEXT Features 22

New standards for usability Less unexpected facility stoppages [PREMIUM Model] [BASIC Model]

Excellent environmental resistance enables robust facility design

Reduces sudden facility stoppages by reducing the number of failures, even in severe environments.
