E3X-DA-S Digital Fiber Sensor

Large, Easy-to-Read Displays: Clear Even from a Distance

The displays are large and easy-to-read, despite the small case.

Settings can be made more simply and confidently with two digital displays. For example, the threshold value can be changed while reading the incident level or a setting can be changed while confirming the setting's function item number.

Seven Convenient Display Formats

An incident level/ threshold display, percentage/ threshold display, and large bar graph display have been added, so you can select the best display method for the application.

Stable, Long-term Performance with APC Function

OMRON provides the industry's most stable long-term detection by using new 4-element LEDs and an APC (Auto Power Control) circuit.

In addition to our unique APC circuit used in the E3X-DA-N Amplifiers to compensate for the deterioration of the LED, the E3X- DA- S uses 4-element LEDs to counteract the deterioration of the light-emitting elements over time and achieve the industry's most stable long-term detection performance.

Furthermore, the circuit is designed with excess light capacity, so the Sensors can be used with high stability regardless of whether the APC circuit is ON or OFF.

Compensate for the effects of contaminants and temperature variation with different operation mode. (Advanced Models)

This operation mode uses a special OMRON algorithm to compensate for slight light level changes due to dirt or temperature variations and detect only the light level changes due to the workpiece.

Slight light level changes can be detected with stability and precision, eliminating the need for time-consuming manual adjustments for light level changes. 

With the Twin-output Amplifiers, output 2 can function as an alarm output (light level operation) to indicate when the light level has changed due to dirt or other causes.

Many Advanced Functions for Even More Applications

Provides high-speed response for miniature workpieces, such as chip parts and devices with short tact times.

Three kinds of timers functions are supported. The timers can be set between 1 ms and 5 s. A one-shot timer is supported in addition to the ON-delay and OFF-delay timers. The Amplifier's ON time can be fixed, which is useful during high-speed workpiece detection.

Area output function can be used for range judgment. (Advanced Twin-output Models)

Operations that required multiple Sensors, such as height measurement, can be performed with just one Sensor. Two threshold levels can be set to easily output within-range and out-of-range outputs.

Remote input function can control the Sensor remotely. (Advanced External-input Models)

Input signals can make various remote settings, such as teaching operations, power tuning, and emitter OFF. This model is ideal for diverse needs, such as checking Sensor operation remotely before operation or making settings remotely because teaching has to be performed often for frequent workpiece model changes.

The counter function can output signal after counter counts up or down. (Advanced External-input Models)

A counter function is built-in, so the number of workpieces can be counted without a separate counter or small PLC that used to be required.

The Same Ease-of-Use as the E3X-DA-N

The E3X-DA-S uses OMRON's own simplified wiring connectors that were introduced with the E3X-DA-N.

In Amplifiers with Connectors, the power supply is distributed to slave connectors through a single master connector. This design has three major advantages. 

1. Wiring time is significantly reduced.

2. Relay connectors are unnecessary, so wiring takes up less space.

3. Storage and maintenance are simpler because it is not necessary to distinguish between master connector and slave connectors on the Amplifier.

Optical communications prevents mutual interface.

Mutual interference is prevented with optical communications, so up to 10 Amplifiers can be mounted together. (The number of Amplifiers depends on the operating conditions.)

Zero reset function immediately resets the digital display to 0.

The zero reset function can immediately reset the digital display to 0 at any time. By setting the reference value to 0, the threshold value can be set while monitoring differences in incident light levels. The threshold value will also shift simultaneously when the zero reset button is pressed.

Reversible Digital Display (Reverse Mode)

The digital display can be reversed to match the Amplifier's mounting direction. 

Environmentally Friendly Design

1  Materials containing lead have been completely eliminated. 

2  The digital display can be turned OFF or dimmed during operation.

When the digital display is viewed infrequently during operation, current consumption can be reduced by dimming the display or turning it OFF entirely.
The display will light up again automatically when an operation key is touched. (Eco-mode can be set from the Mobile Console only.)

3  Cable disposal is not required during maintenance.

Further Improvements to the Mobile Console

Group Power Tuning

With the group power tuning function, power tuning is possible for multiple Sensors at the same time.

Improved Mode Lock Function

Settings can be customized for different applications by locking out unnecessary function blocks within function settings.
