3.1 Mechanical Installation
This section provides instructions for installing the Modline 5 Sensor. Sighting, aiming, focusing and
resolving targets are explained. Mounting and protection of the Sensor in hot and dirty environments
using installation, air purging and water cooling accessories are presented.

Figure 2: Standard Sensor Figure 3: Sensor with Dirty Window Detector
Two Sensors types are available in the Modline 5 Series, standard Sensor or Sensor with the Dirty
Window Detector option. The front of the standard Sensor consists of a front objective lens only. The
Sensor with the Dirty Window Detector option has internal components and an external protection
window located in front of the objective lens. A hooded mirror extends out in front of protection
window. The sensors are illustrated in the photographs above and below.
The Patented Dirty Window Detector option, IRCON, inc. Patent Number 5812270, checks the Sensors
front window for loss of signal caused by a buildup of contaminants. A Coarse or Sensitive level of
signal loss can be selected. Visual Alarms and a relay output are provided to indicate window
contamination.
Dimensions for the Sensor with the DWD are slightly different because of the additional components.
Measurement of the optical working distance on the standard Sensor is made from the front surface of
the unit. The working distance determination on the Sensor with DWD requires a simple calculation.
Measurement is made from the front tip of the hooded mirror and 66 mm (2.6 inches) is added to the
distance to compensate for the extended optics.
