The D-Box is a very robust and space-saving, explosion-proofed (flameproof enclosure “d”) switch box. As with all ROTECH products, numerous parts from other limit switch boxes can be built in. The explosion proof function of this series is dictated by the housing of the box.
There are two possible housing materials:
aluminium as standard material and stainless steel for use in aggressive environments e.g. onshore and offshore areas.
Vision beacon as an option
With built-on solenoid valve
Variable possibilities of sensors and microswitches
