1.5 Proper Environment
- Protection class for sensors: IP 65 (only applies in the case of connected output connectors or installed
protective caps)
- Temperature range:
Operation: 0 ... +45 °C (+32 ... +113 °F) (with free air circulation)
Storage: -20 ... +70 °C (-4 ... +158 °F)
- Ambient pressure: Atmospheric pressure
- Humidity: 5 - 95 % (non condensing)
Optical paths during operation are excluded from the protection class. Contamination of the paths causes
impairment or failure of the function.
Use only shielded lines or original cables from the accessories program for the power supply connection or
the outputs.
Also observe the assembly and installation instructions, see 5.
The IP 65 protection class is a specification that is limited to protection from dust and water.
Oil, steam and emulsion effects are not included in this protection class and must be evaluated separately.

2. Laser Safety
2.1 Laser Class 2M
The scanCONTROL 29xx sensors operate with a semiconductor laser with a wavelength of 658 nm (visible/
red) or 405 nm (visible/blue).
The sensors fall within laser class 2M. The laser is operated on a pulsed mode, the maximum optical power is
≤ 8 mW (scanCONTROL 29xx-10/BL ≤ 7 mW). The pulse frequency depends on the adjusted measuring rate
(0 ... 4 kHz). The pulse duration of the peaks is regulated depending on the measuring rate and reflectivity of
the target and can be 1 ... ∞µs.
iObserve the laser protection regulations.
When operating the scanCONTROL 29xx sensors, the relevant regulations according to IEC 60825, Part 1 of
05/2014 and the applicable accident prevention regulations must be followed.
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.
- Directly 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 not subject to notification and a laser protection officer is not required.
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.
Laser radiation. Close
your eyes or immedi-
ately turn away if the
laser beam hits the eye.
Irritation or injury of the
eyes possible

2.2 Laser Class 3B
The scanCONTROL sensors operate with a semiconductor laser with a wavelength of 658 nm (visible/red).
The sensors fall within laser class 3B. The laser is operated on a pulsed mode, the maximum optical power is
≤ 50 mW. The pulse frequency depends on the adjusted measuring rate (0 ... 4 kHz). The pulse duration of
the peaks is regulated depending on the measuring rate and reflectivity of the target and can be 1 ... ∞µs.
iObserve the laser protection regulations.
iSensors of laser class 3B require an external key switch to switch off the laser, see 5.2.6.
When operating the scanCONTROL 29xx sensors, the relevant regulations according to IEC 60825, Part 1 of
05/2014 and the applicable accident prevention regulations must be followed.
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 maxi-
mum permissible exposure are exceeded.
Class 3B laser sensors are notifiable and a laser protection officer is required.
Mark the laser area recognizable and everlasting. During operation the laser area has to be restricted and
marked.
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.

For repair and service purposes, the sensors must always be sent to the manufacturer.
If the sensor is on the laser output can be reduced to 8 mW with the software.
Reducing the laser output to 1 mW is not possible. Reducing the laser output from 20 mW to 8 mW with a
software affects not the laser class!
Beam attenuator

beam attenuator
Fig. 9 Sensor with open
beam attenuator (measur-
ing)
Laser products certified as Class 3B products (EN 60825-1) require a beam attenuator, see Fig. 8, see Fig. 9,
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, see 5.2.6 (laser switch-off).

3. Functional Principle, Technical Data
3.1 Short Description
3.1.1 Measuring Principle
The scanCONTROL 29xx sensor operates according 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 sys-
tem and evaluated in two dimensions.
The laser line triangulation corresponds in principle to the triangulation of a laser point. However, during the
measurement a row of lines are simultaneously illuminated by the laser line. Apart from the distance infor-
mation (Z-axis), the exact position of each point on the laser line (X-axis) is also detected and output by the
system.
3.1.2 System Setup
The scanCONTROL 29xx sensor is a compact sensor with an integrated controller. All necessary integral
parts are combined in one housing.
3.1.3 Special Performance Features
- scanCONTROL 29xx is characterized by its compact design and high speed along with high measuring
accuracy. 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 enables
uniform image focusing over the whole depth of the measuring range (Z-axis).
- The scanCONTROL 2910/2960 series with integrated profile evaluation works even without a PC in con-
junction with saved configurations. The sensor performs 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 (Mod-
bus 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 scanCONTROL Output Unit,
which transforms the determined measurement signals in switching and analog signals for further process-
ing in a PLC.
- scanCONTROL Gateway allows for scanCONTROL SMART sensors to be integrated into various fieldbus
systems (PROFINET, EtherNet/IP, EtherCAT).

3.1.4 Advantages of the Used Sensor Array (Difference to Conventional Video Arrays)
- A global shutter (high speed shutter) for the whole profile enables a high profile accuracy for fast moving
objects without “tilting”.
- The array enables the simultaneous exposure and reading of the previous image. Thus, the exposed time
can be longer with the same profile frequency, and therefore dark objects can be measured at high speed.
3.1.5 Further Advantages
- External synchronization and triggering
- Serial interface (RS422) for communication with PLC or PC
- Digital switching inputs, TTL or HTL
- The automatic control of the exposure time enables consistent measurement results with changing sur-
faces. It can be switched off on request.
- Ethernet 100/1000 Mbit as fast standard connection to PC
