Stable, Long-term Performance with OMRON's APC Function
Many Advanced Functions for Even More Applications
Fastest in the Industry
Detecting Leads on Electronic Parts
Highest Level of Stability
OMRON provides the industry's most stable long-term detection
by using new 4-element LEDs and an APC (Auto Power Control) circuit.
Provides high-speed response for miniature workpieces, such as chip parts and devices with short tact times.
In addition to our unique APC circuit used in the
Earlier Method
New Method
Three kinds of timer 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.
E3X-DA-N Amplifiers to compensate for the dete-
rioration of the LED, the E3X-DA-S uses 4-ele-
ment LEDs to counteract the deterioration of the
light-emitting elements over time and achieve the
industry's most stable long-term detection perfor-
mance.

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

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.

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.
Detecting Seals
Slight light level changes can be detected with stability and
precision, eliminating the need for time-consuming manual ad-
justments for light level changes.
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.
Detecting marks in a dusty environment
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.
