General Information LDS30 Manual
Page 8 ASTECH GmbH
1General Information
The Laser Distance Sensor LDS30 was developed for industrial applications. It
enables non-contact measurement of distances in a large working range and
with a high sampling rate up to 30 kHz to almost any diffusely reflecting
surface to 30 m and up to 250 m on reflectors. The sensor uses an eye-safe
laser radiation at a wavelength of 905 nm (infrared).
It is available as a complete device LDS30A with various interfaces in an IP67
enclosure or as a module LDS30M for system integration. The IP67 model
variant is impact and shock resistant and ideally suited for use in harsh
industrial environments.
The LDS30A has an RS-232 or RS-422 interface, an analog output and 2 digital
outputs. The device is easy to install and operate. The module has just a RS-
422 interface with CMOS level.
The LDS30A is characterized by very compact and rugged design, easy
mounting, low power, adjustable switching outputs and the ability to set user-
specific parameters. This opens up a variety of uses in industrial applications.
Rapid process monitoring
Position monitoring
Level measurement
Monitoring of object movements
Positioning of cranes and loading equipment
Measurement of inaccessible points, for example in cavities, pipes
and containers
Particularly suitable for use in scanners
The LDS30 sensor operates on the basis of time of flight measurement. Short
laser pulses are transmitted. The light pulse reflected from the target is
detected by the receiver. The distance can be determined by the time shift.
The measurement range depends on the reflectivity and the surface type of
the measuring target.

LDS30 Manual Safety advice
ASTECH GmbH Page 9 Seite 9
2Safety advice
2.1 Basic safety advice
Please read the safety and operating advice carefully, and observe the advice
when operating the device.
Danger of Laser radiation
Do not open the LDS30, otherwise Laser radiation can be emitted
that can cause eye injuries. Please observe all information and
guidelines for operating the Laser.
The LDS30 corresponds to Laser class 1 based on the standard
IEC 60825-1:2007. The radiation of class 1 Lasers does not imply
any danger to the human eye; any injury of the human eye can be
excluded.
Danger, electric shock
The LDS30 may only be opened for repair purposes by the
manufacturer. If the device is opened arbitrarily without
authorization, all warranty claims will expire.
The operating and storage conditions have to be observed (see
chapter 3). The inobservance of this advice and the adverse use of
the device can lead to injuries of the user or to damage of the
device.
Connectors may not be plugged or unplugged when voltage is
applied. All installation work may only be carried out when no
voltage is applied.
The device may only be operated as intended and in faultless
condition.
Safety installations must not be rendered ineffective.
Safety and warning signs must not be removed.
Protection Class 3, low voltage

Safety advice LDS30 Manual
Page 10 ASTECH GmbH
The device LDS30 operates with low voltage of DC 10 to 30 volts.
Protection degree: In accordance with the Protection Degree IP67,
the LDS30A is protected against jet water and dust, and against
short submersion into water.
When operating the device under extreme outdoor environmental
conditions, the use of additional weather protection is
recommended (e.g. a cover plate with a short distance to the
LDS30A). Rapid temperature changes can lead to humidity entering
the device.
The device is not shatter-proof. Do not let the device fall onto the
ground, and avoid any shock.
The device is delivered in a solid cardboard box, which is suited for
the transport of the device.
The device may not be used in explosive environments; otherwise
there is the danger of damage to the LDS30 and the surrounding
equipment, and of injuries of the user.
2.2 Safety advice for Laser Class 1
The LDS30 is a calls 1 Laser product based on the norm
IEC 60825-1:2007. The laser radiation of class 1 Lasers does not
imply any danger to the human eye; any injury of the human eye
can be excluded
2.3 Advice for operating device
The LDS30 should not be put into operation when optical parts are
fogged or dirty. The optical components of the equipment should
not be touched with bare hands!
Dust and dirt are removed from the optical components with
extreme caution! Cleaning with solvents or mechanical means is
not allowed.
