Inductive Proximity Sensor
E2CA
Linear Output Proximity Sensor with
High-accuracy Resolution
Resolution is 0.05% of the maximum sensing
distance. The model with a sensing distance of
1.2 mm ensures a resolution of 0.6 m.
Models with response frequencies ranging from 10
to 3 kHz are available.
The M30-size model ensures a sensing distance of
10 mm.
Satisfies IEC IP67 requirements, thus detecting the
displacement of metal objects without being
influenced by water and oil spray.
The E2CA has a standard linear output of 4 to
20 mA and connects to the Linear Discrimination
Unit, Digital Panel Meter, and I/O Unit of the
Programmable Controller.
The E2CA’s compact amplifier can be plugged into
surface mounting sockets thus greatly reducing
wiring effort and ensuring easy mounting.

E2CA
Enclosed Mounting
If the Y92F-30 Adapter is used, insert the E2CA into the square hole
from the front side of the panel and slide the Y92F-30 onto the E2CA
from the rear side of the E2CA. Then press the Y92F-30 so that the
space between the Y92F-30 and the panel is reduced as much as
possible. Finally, secure the Y92F-30 with screws.
E2CA
Removing the Amplifier Unit
If the Y92F-30 is used, loosen the screws of the Y92F-30, spread
out the hooks, and remove the Y92F-30.

Others
The accuracy of the E2CA will vary with the on-site environment.
The resolution, temperature characteristics, and voltage character-
istic linearity are especially affected. Therefore, keep the on-site en-
vironment as suitable for the E2CA as possible.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
