Overview

The Series BMHE Heated Enclosure is designed to offer weather protection for a

MINI-ARRAY emitter or receiver in an outdoor application such as a toll booth.

The Enclosure has a laminated safety glass window with a series of resistance wires.

The resistance wires connect through two thermostats to a power source to heat the

glass as necessary to prevent condensation, ice or snow from inhibiting the beams.

When humidity inside the enclosure rises, a humidistat prompts the heater to warm

the window, to prevent condensation.

The Series BMHE MINI-ARRAY Heated Enclosure is designed to accommodate MINI-

ARRAY emitters and receivers 4', 5', or 6' long, with enough extra space at top and

bottom to ensure accurate mounting.
