2. Laser Safety
2.1 General
The scanCONTROL 25xx sensors operate with a semiconductor laser having a wavelength of 658 nm (visible/
red) resp. 405 nm (visible/blue).
The laser operation is indicated visually by the LED on the sensor.
When operating the scanCONTROL 25xx sensors, the relevant regulations according to IEC 60825, Part 1 of
05/2014 and the applicable accident prevention regulations must be followed.
The laser warning labels for Germany have already been attached. For other non German speaking coun-
tries, an IEC standard label is included in delivery and the versions valid for the user’s country must be at-
tached before the device is put into operation for the first time.
iIf both warning labels are covered over when the unit is installed, the user must ensure that supplemen- tary labels are applied.
Laser Operation is indicated by LED, see 3.3.
The housings of the scanCONTROL 25xx optical sensors must only be opened by manufacturer, see 9.
For repair and service purposes, the sensors must always be sent to the manufacturer.

be 1 µs up to infinite.
iObserve the laser protection regulations.
Accordingly, the following applies:
Laser equipment of the Class 2M can be employed without further protective measures, when deliberate
viewing into the laser beam or into a beam reflected by mirrors is not longer than 0.25 s. Directly looking into
the beam can be dangerous, if the eye-closure reflex is consciously suppressed, e.g., during adjusting. Di-
rectly looking into the beam with optical devices, such as magnifying glasses, is dangerous. Since generally
the presence of the eye-closure reflex should not be assumed, one should close the eyes or immediately turn
away if the laser radiation impinges on the eye.
Lasers of Class 2M are subject to notification and a laser protection officer is not required.
Attach the following warning labels to the cover (front and rear side) of the housing:

be 1 µs up to infinite.
iObserve the laser protection regulations.
iSensors of laser class 3B require an external key switch to switch off the laser, see 5.2.6.
Accordingly, the following applies: The accessible laser radiation is harmful to the eyes, and often also for the
skin. Looking directly into the laser beam is harmful to the eyes. Reflections of shiny or mirroring surfaces are
also harmful to the eyes. The accessible laser radiation is harmful to the skin with laser class 3B devices if the
values of the maximum permissible exposure are exceeded.
Class 3B laser sensors are notifiable and a laser protection officer is required. Mark the laser area recogniz-
able and everlasting. During operation the laser area has to be restricted and marked.

surements
Laser products certified as Class 3B products (EN 60825-1) require a beam attenuator, see Fig. 7, see Fig. 8,
other then the key-operated control. The beam attenuator prevents access to all laser and collateral radiation.
To open or close the aperture please follow the steps below:
Loosen the knurled screw.
Change the attenuator position and tighten the knurled screw.
The laser aperture must be open during measurement. Please observe the notes on external laser switching,
see 5.2.6.

Functional Principle, Technical Data

3. Functional Principle, Technical Data
3.1 Short Description
3.1.1 Measuring Principle
The scanCONTROL 25xx sensor operates accord-
ing to the principle of optical triangulation (light
intersection method):
- A laser line is projected onto the target surface
via a linear optical system.
- The diffusely reflected light from the laser line
is replicated on a sensor array by a high quality
optical system and evaluated in two dimensions.
The laser line triangulation corresponds in principle
to the triangulation of a laser point. In addition,
during the measurement a row of lines are simulta-
neously illuminated by the laser line. Apart from the
distance information (Z-axis), the exact position of
each point on the laser line (X-axis) is also acquired
and output by the system.

3.1.2 System Setup
The scanCONTROL 25xx sensor is a compact sensor with an integrated controller. All necessary integral
parts are combined in one housing.

Page 15
Functional Principle, Technical Data
scanCONTROL 25xx
3.1.3 Special Performance Features
- scanCONTROL 25xx stands out due to its compact design. A special line-scanning optical system ensures uniform exposure of the
measuring field.
- The sensor array is arranged in the sensor head according to the Scheimpflug condition which facilitates uniform image focusing
over the whole depth of the measurement range (Z-axis).
- The scanCONTROL 2510 series with integrated profile analysis works even without a PC in conjunction with saved configurations.
The sensor runs the profile measurement internally and calculates default measured values such as angle or edge position.
Besides measurement value output via Ethernet (Modbus TCP protocol, UDP protocol) and RS422 (Modbus RTU protocol or ASCII
format), additional switching signals (results of the determination of limit values) and analog measurement values can be output.
This is done by an optional 2D/3D Output Unit, which transforms the determined measurement signals in switching and analog
signals for further processing in a PLC.
- 2D/3D Gateway allows for scanCONTROL SMART sensors to be integrated into various fieldbus systems (PROFINET, EtherNet/IP,
EtherCAT).
3.1.4 Advantages
- External synchronization and triggering
- Serial interface (RS422) for communication with PLC or PC
- Digital switching inputs, selectable TTL or HTL
- The automatic control of the exposure time enables consistent measurement results with changing surfaces. This function can be
switched off on request.
- Ethernet 100/1000 Mbit as fast standard connection to PC
