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.
