Intended Use
- The measuring system is designed for use in an industrial environment. It is used for
displacement, distance and movement measurement, thickness measurement,
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 only be used in such a way that no persons are endangered or machines are dama-
ged in the event of malfunction or total failure of the sensor.
Take additional precautions for safety and damage prevention in case of safety-related applications.
Proper Environment

- Controller protection class: IP40
Lenses are excluded from protection class. Contamination of the lenses causes impairment or failure of the function.
- Operating temperature range
Sensor: +5 ... +70 °C ( +41 ... +158 °F)
Controller: +5 ... +50 °C (+41 ... +122 °F)
- Storage temperature range: -20 ... +70 °C (-4 ... +158 °F)
- Humidity: 5 - 95 % (non-condensing)
- Ambient pressure: Atmospheric pressure
- EMC: As per EN 61000-6-3 / EN 61326-1 (Class B) Emitted interference; EN 61000-6-2 / EN 61326-1 Immunity to
interference

Sensor Cable, Optical Fiber
The sensor is connected to the controller by means
of an optical fiber.
- Do not shorten or extend the optical fiber.
- Do not pull or carry the sensor by the cable.
Do not kink the sen-
sor cable.
Do not squash the
sensor cable, do
not use cable ties to
secure it.
Do not pull the sensor
cable over sharp
edges.
Do not pull on the
sensor cable.
The plugs may only be cleaned by persons with the
appropriate expertise.

General Rules
Do not
- any contamination of the connector, e.g., dust
- apply any mechanical stress to the optical fiber
- curve the cable to a significant extent
Never bend the sensor cable more tightly than the per-
mitted bending radius.
R
If the cable is immova-
bly routed:
R = 30 mm or more
If the cable is movably
routed:
R = 40 mm or more

Initial Operation
confocalDT 2421 / 2422
Initial Operation
iThe measuring system is ready to use approx. 10 s after the controller is switched on.
To ensure precise measurements, let the measu-
ring system warm up for approx. 30 minutes.
The controller is shipped with the factory-set IP address
169.254.168.150.
You can query the IP addresses of the controllers that
are connected to a PC or network by using the sen-
sorTOOL.exe program. You can find this program on-
line at https://www.micro-epsilon.de/download/software/
sensorTOOL.exe.
Launch the sensorTOOL and click the button.
Select the controller from the list.
Click the Open Website button to connect the cont-
roller to your default browser.
The start screen of the controller software should now be
displayed in the web browser. You can configure the soft-
ware using the web pages or ASCII commands integrated
in the controller.
Selecting the Sensor
Go to the Settings > Sensor menu.
Select the connec-
ted sensor for the
relevant channel. Pay
attention to type and
serial number.
