2.4 MECHANICAL INSTALLATION
Because the DM3610 dimensioners are measuring devices, calibration and proper usage of
this devices are necessary for proper operation. The DM3610 dimensioners are shipped from
Datalogic calibrated. It is therefore essential that the units be mounted exactly as detailed on
the application drawing to retain proper calibration. The critical parameters are:

Minimal vibration of unit on mounting structure - any movement of the DM3610
dimensioners due to vibration/swaying of the mounting structure will directly impact
the dimensioning accuracy.

Mounting height above the conveyor.

The dimensioner scan lines must be perpendicular to conveyor travel.

If used, the photoelectric sensor’s beam path must be parallel to the dimensioner
scan line(s).

Tachometer assembly in contact with the same conveyor belt where the dimensioning
scan lines are projected, to insure proper speed indication

The dimensioner scan lines should be located at least 7 - 8 cm [3 inches] away from
any other scan pattern on the conveyor belt, to eliminate the possibility of reflections
interfering with dimensioning accuracy.
2.4.1 Dimensions and Clearances
The overall dimensions of the DM3610 are provided in
section 2.4.6 and chapter 8, Technical
Features.
The DM3610 is a sealed, unventilated unit. Mounting the unit w
ith 300 mm [12”] of clearance
(front, top, and sides) is recommended for ease-of-access and cooling.
IMPORTANT:
For installation, maintenance and service reasons,
approximately 300 mm [12 inches] of clearance is recommended.
2.4.2 Physical Support Requirements
For details on the weight of the DM3610 dimensioner,
see chapter 8, Technical Features .
Multiple-head systems may include further details on the physical support requirements with
any application-specific documentation provided.
2.4.3 Vibration Limitations
The DM3610 is designed and tested to withstand continuous sine wave vibrations between
10 and 500 hertz (limited to a displacement of 0.40 mm [0.0157 inches] for frequencies
between 10 and 50 Hz and limited to 2 G acceleration for frequencies between 50 and
500 Hz).
