Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use this product under ambient conditions that exceed the
ratings.
● Design
Influence of Surrounding Metal
When mounting the Sensor within a metal panel, ensure that the
clearances given in the following table are maintained. Failure to
maintain these distances may cause deterioration in the performance
of the Sensor.
Influence of Surrounding Metal (Unit: mm)
Influence of Temperature
Incorrect operation may occur if there is a large temperature
difference between the Sensor Head and the Amplifier Unit.
Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
Mutual Interference (Unit: mm)
*1. Values in parentheses apply to Sensors operating at different frequencies.
*2. Mutual interference will not occur for close-proximity mounting if models with
different frequencies are used together.
● Mounting
•Refer to the following table for the
torque and tightening ranges
applied to mount the E2EC-C
Unthreaded Cylindrical Model.
Tightening must be as given in
the following table.
Permissible Tightening Range and Torque
•The tightening torque applied to the E2EC-
X4D@ Threaded Cylindrical Models must be
12 N·m max.
Amplifier Mounting Bracket for DC 2-Wire Models
Mounting
1. Insert the Amplifier into the trapezoidal end (i.e., the fixing side) of
the Mounting Bracket.
2. Press the other end of the Amplifier onto the Bracket.
Dismounting
1. Lightly press the hook on the Mounting Bracket with a flat-blade
screwdriver.
2. The Amplifier will be automatically released due to the spring force
of the Mounting Bracket.
