Intended Use
- The measuring system is designed for use in an industrial environment. It is used for
measuring displacement, distance movement and thickness,
measuring the position of parts or machine components.
- The measuring system must only be operated within the limits specified in the technical data.
The measuring system must be used in such a way that no persons are endangered or machines and other mate-
rial goods are damaged in the event of malfunction or total failure of the controller..
Take additional precautions for safety and damage prevention in case of safety-related applications.

Measurement Setup, Operating Multiple Sensors
Sensors of the eddyNCDT 3060 series cannot be synchronized. Observe the following installation information regard-
ing the minimum distance between two sensors:
- 3x sensor diameter distance between two unshielded sensors with equal carrier frequency (e. g. low frequency)
- 1.5x sensor diameter distance between two shielded sensors with equal carrier frequency (e. g. low frequency)
- two nearby mounted sensors only as low frequency and high frequency models

Installation and Assembly
No sharp or heavy objects should be allowed to affect
the cable sheath of the sensor cable, the supply cable
and the output cable.
iA damaged cable cannot be repaired. Tension on
the cable is not permitted!!
Sensor
Unshielded sensors
- Type designation: ES-Ux
- Construction: The sensor cap with
encapsulated coil consists of elec-
trically non-conducting materials.
iIn the radial direction metal
parts in the vicinity may behave
similar to the measuring object,
rendering the measurement
result inaccurate. Please note
this by selection of material
for sensor mounting and their
setup.
Shielded sensors
- Type designation: ES-Sx
- Construction: The sensor en-
closed up to its front face with
a steel housing with a mount-
ing thread. With it the sensor
is shielded from interference
through radially near located
metal parts.
Start of Measuring Range
For each sensor a minimum distance to the measuring
object must be maintained. This avoids a measurement
uncertainty due to the sensor pressing on the measuring
object and mechanical damage to the sensor/target.
SMR
Sensor Target

Start of measuring range (SMR), the minimum distance
between sensor face and target
Eddy-current displacement sensors can be affected in
their measurement properties by a metallic holder. De-
pending on the sensor type, the following sensor mount-
ing should be preferred:
- unshielded sensors: Standard mounting
- shielded sensors: Flush mounting

Installation and Assembly
eddyNCDT 306x
Standard Mounting
The sensors protrude beyond
the metal holder. The installation
scenario depicted is used for fac-
tory calibration of the sensors at
Micro-Epsilon.
The technical sensor data correspond to standard
installation conditions. If you want to achieve the values
indicated in the data sheet, we recommend to install the
sensor in the same way as it was during calibration.
Sensors with a thread
Insert the sensor through the hole in the sensor holder.
Screw the sensor tight.
Turn the mounting nuts from the delivery on both sides on the thread protruding from the holder.
Tighten the mounting nuts carefully to avoid damage, particularly to smaller sensors.
iPrefer the standard mounting of the sensor, because the optimum measurement results can be achieved with
this method!

Flush Mounting
Flush mounting does not cor-
respond to factory calibration.
Micro-Epsilon recommends to
carry out at least a 3-point field
linearization.
Sensors with a thread
Mount shielded or unshielded sensors flush in a sensor holder of insulating material (plastic, ceramic, et cetera).
Mount the shielded sensors flush in a metal sensor holder.
Mount the unshielded sensors flush in a metal sensor holder. Make sure that a recess of a size three times the
sensor diameter is used.
In all mounting cases screw the sensor into the threaded hole and lock it with the mounting nut.
Tighten carefully to avoid damage, particularly to smaller sensors.

iLinearize the measuring system, if possible, when
it is exactly arranged (in the same way as it will be
arranged later during the measurement process).
