LS113PS

General
The LS113PS is an opto‐electronic distance measuring module for industrial applications.
Equipped with a Profibus® DP interface, the LS113PS can easily be integrated into any fieldbus‐driven
process controller.
The additional SSI interface provides another convenient option for controlled ope‐ ration of the measuring
module.
A compact and robust design shape combines with low power consumption, selectable switching outputs
and the possibility to set specific application parameters to warrant flexibility in use.
Laser Classification
The LS111/112FA2 is a class 2 laser product as stipulated in IEC825‐1/DIN EN 60825‐1:2001‐11 and a class II
product under FDA21 CFR. In the event of accidental, short‐ time laser exposure, the human eye is
sufficiently protected by its own optico‐facial winking reflex. This natural reflex may be impaired by
medication, alcohol and drugs. Although the product can be operated without taking special safety
precau‐ tions, one should refrain from directly looking into the laser beam. Do not direct the laser beam
onto persons.
Caution:
There is class 2 laser radiation. Do not look into the beam!
General Product Description
The LS113PS is a laser distance measuring module to determine distances from 0.1 m to 30 m, using natural
surfaces, or to measure distances up to 150 m with a target reflector. Providing a red laser sighting point,
the LS113PS allows you to unequivocally mark a particular target. Its effective operating range depends on the
reflectance and surface qualities of the targets being sighted.
The module works based on comparative phase measurement. It emits modulated high‐frequency light
which is diffusely reflected back from the target with a certain shift in phase to be compared with a
reference signal. From the amount of phase shift, a required distance can then be determined with millimeter
accuracy.
A distance measurement cycle can be triggered:
• via the Profibus
• from an external trigger source (external trigger mode)
• via the SSI.
Special performance features are:
• Profibus interface
• Broad range of parameter setting options via Profibus
• SSI interface
• Two switching outputs, each with selectable parameter settings
• External trigger input, with selectable parameter settings
• Capable of operating at outdoor temperatures from +15°C to +30°C
with ±2 mm accuracy
• Up to 30 m reach for distance measurement, with potential for 150 m reach
if additional reflectors are mounted onto the target
• Visible laser beam for easier sightingl. 2/6
