Conveyor Components Co. has added "dual-rated" enclosures to their line of conveyor controls. These enclosures are rated for a combined area classification of NEMA 4 weatherproof and NEMA 9 dust ignition proof, allowing the units to be placed outdoors in hazardous areas. Most of the units are UL listed and CSA certified.

The dual-rated enclosures encompass the Model RS-D and Model RSB-D pull cord or cable operated stop control, the Model TA-D belt alignment control, the Model DB-100D belt rip detector, the Model PCL/R/D-D pull cord, the Model CR-D level control and plugged chute detector and the Model FS-D dry bulk material flow control series. The Model CMS-X zero speed control is also dually rated for NEMA 4 and NEMA 9 environments with a five amp unpowered output relay instead of a microswitch arrangement.
