Darui Electric recommends
The explosion-proof operating column is a flexible control system that can provide customers with standard or specially required local control units or display units. We offer three standard enclosure models to suit three different control and display situations. You can also combine up to three ComEx enclosures together as needed. The cable entry size can be M20x1.5 or M25x1.5. The material can be plastic or metal. Plastic cable entries are fixed directly by thread, no tightening nut required. Metal cable entries are fixed by a metal grounding plate inside the enclosure. An operating column can have up to two M20 cable entries. For ease of on-site operation, each plastic enclosure is equipped with a position label.
