Omron E4PA-N Manual

Ultrasonic Displacement Sensor
E4PA-N
Now, more advanced with a new mutual
interference prevention function.
• Long-distance detection of up to 6,000 mm supports a wide vari-
ety of applications.
• The Sensor is not affected by the color or material of objects.
• A setting plug with temperature compensation makes it easy to
set the sensing range.
• Mutual interference prevention.
Application Examples
Detecting slackness in sheet
materials
Features
■
High-precision detection with a
wide range of measurements.
Four types of Sensors are available with max-
imum sensing distances of 0.5 m, 2 m, 4 m,
and 6 m. With the 0.5-m type, a repeat accu-
racy of 1 mm or better has been achieved.
■
A setting plug with a temperature compensation
function makes it easy to set the sensing range.
The sensing range can be set by the Setting Plug,
which is included with the Sensor. No special con-
troller is required. The Setting Plug's built-in tem-
perature sensor provides superior temperature
characteristics of ±1% FS.

The Sensor is ultrasonic, so it is not affected by the
color of objects.
A variety of materials can be measured, including transparent and
reflective objects. Measurements are performed with no contact, so
even highly-viscous liquids are no problem.

The mutual interference prevention function allows
up to five Sensors to be used in close proximity.
