Signs and Symbols
Warning
This symbol signals passages in the manual which must be observed at all times. Non-compliance can
cause injuries or material damage.
Warning Laser
This symbol appears in front of warning passages concerning the danger of laser beams.
Information
This symbol signals passages with useful information.
Safety information
It is essential that this manual, and the safety information in particular, is read, thoroughly understood and observed before setting the VDM18 sensor into operation.
The VDM18 sensor may only be connected, mounted and adjusted by qualifi ed personnel.
Interventions and alterations to the device are not permissible!
The VDM18 sensor is not a safety component as described by EU machine directives and must
never be used in applications where human safety is at risk.
The VDM18 sensor complies with laser protection class 2 according to DIN EN 60825-1, status
2008-05. The technical requirements comply with EN 60947-5-2, 2000 edition.
Never look into the path of the laser. Do not suppress the refl ex to close the eyelids.
Gazing into the beam path for longer periods can damage the retina of the eye.
When mounting the sensor, ensure if possible that the beam path is sealed off at the end. The
laser must not be directed at people (head height). When aligning VDM18, ensure that there are
no refl ections on refl ective surfaces.
Should the safety label on the VDM18 sensor be partly covered due to its installation position,
other safety labels are to be positioned on visible parts of the sensor. When applying the new
safety label, make sure that you cannot look into the laser beam whilst reading it.

operating instructions
Appropriate use
The VDM18 sensor is not authorised for use in protecting human safety on machines and during
technical applications.
The VDM18 is an optical sensor and measures distances without contact. When combined with another VDM18
sensor, the thickness of objects can also be measured.
Performance characteristics
• Operating range VDM18-100: 30 – 100 mm
• Operating range VDM18-300: 80 – 300 mm
• 2 digital outputs
• Analogue output 4-20 mA
• Compact design 50 x 50 x 17 mm
• High resolution (0.1 % of measuring range)
• Option /88 with serial bus interface (RS 485 half-duplex)
• “Teach-in” settings also possible per software
• Wide functional range
Mode of function
The VDM18 sensor measures according to the principle of triangulation. The distance between the object and sensor
is determined on the basis of the position of the light spot on the detector.

Mounting
Sensor alignment
Position VDM18 in a way that the distance to the object is within the working range of the sensor.
Screw the VDM18 sensor to the mounting bracket, e.g. type OMH-VDM18 (not included in delivery) or a suitable
device. Only use the holes provided in the housing (see dimensioned drawing) for this purpose.
If steps, moving or striped objects are to be detected, the front panel of the sensor should be mounted at a right
angle to the direction of movement or stripes (Illustr. 5 + 6).
With very refl ective objects, the sensor must be mounted at an angle of approx. 5° (Illustr. 7).
To optimise measurements, the VDM18 sensor is to be given constructive protection from vibrations.
The VDM18 sensor is now mounted.
