Electrical Installation

Two-wire models (output option 0):

Air Purge Collar

The air purge collar is used to keep dust, fumes, moisture and other contaminants away

from the lens. Air flows into the fitting on the side and out of the aperture at the front.

________________________________
Fixed Mounting Bracket

The L-shaped fixed mounting bracket offers a rigid support for the sensor

and allows fine rotational adjustment about one axis.

______________________________
Adjustable Mounting Bracket

The adjustable mounting bracket consists of a fixed mounting bracket

plus another L-shaped bracket. When assembled as shown, the adjustable mounting

bracket offers a rigid support for the sensor and allows fine two-axis adjustment.

________________________________

Air/Water Cooled Housing

The air/water cooled housing allows the sensor to withstand ambient temperatures above the normal 70°C limit.
Depending on the degree of cooling required, air or water may be used as the cooling fluid.
To prevent condensation forming on the lens, an air purge collar is included with this item.
The air/water cooled housing must be ordered with the sensor and cannot be fitted by the user.
