2.1 General

The scanCONTROL 30xx sensors operate with a

semiconductor laser having a wavelength of 658 nm

(visible/red) resp. 405 nm (visible/blue).

When operating the scanCONTROL 30xx 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

countries, an IEC standard label is included in deliv-

ery and the versions valid for the user’s country must

be attached before the device is put into operation for

the first time.

2.2 Laser Class 2M

The sensors fall within laser class 2M. The laser is operated on a pulsed mode, the maximum optical power

is ≤ 10 mW or ≤ 12 mW. The pulse frequency depends on the adjusted measuring rate (0 ... 25 kHz). The

pulse duration can be 7 µs up to infinite.

i

Observe 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. 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.

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. 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.

Functional Principle, Technical Data

3. Functional Principle, Technical Data

3.1 Short Description

3.1.1 Measuring Principle

The scanCONTROL 30xx sensor operates ac-

cording 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 matrix 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 simultaneously illuminated by the

laser line. Apart from the distance informa-

tion (Z-axis), the exact position of each point

on the laser line (X-axis) is also acquired and

output by the system.

X-axis (profile width)

range Z-axis

(profile height)

3.1.2 System Setup

The scanCONTROL 30xx sensor is a compact sensor with an integrated controller. All necessary integral

parts are combined in one housing.

Page 14

Functional Principle, Technical Data

scanCONTROL 30xx

3.1.3 Special Performance Features

- scanCONTROL 30xx features speed and compact design with simultaneously high measurement accu-

racy. A special line-scanning optical system ensures uniform exposure of the measuring field.

- The sensor matrix 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 30xx 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 mea-

sured 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 Matrix (Difference to Conventional Line Scanners)

- A global shutter (high speed shutter) for the whole profile enables a high profile accuracy for fast applica-

tions without “tilting”.

- The matrix enables the simultaneous exposure and reading of the previous image. Thus the exposure time

is longer at the same profile frequency. With it also dark objects can be measured with a high rate.

- The High Dynamic Range mode (HDR) provides optimal measuring data on difficult target surfaces.

3.1.5 Further Features

- External synchronization and triggering

- Serial interface (RS422) for communication with PLC or PC

- Digital switching inputs, selectable TTL or HTL (selectable Pull-up or Pull down behaviour)

- The automatic control of the exposure time enables consistent measurement results with changing sur-

faces. This function can be switched off on request.

- Ethernet 100/1000 Mbit as fast standard connection to PC
