Explosion-proof Anti-corrosive Operating Column

Short Description:

The explosion-proof operation column is a flexible control system that can provide customers with standard or local control units or display units with special requirements. We provide three types of standard enclosures to adapt to three different situations of control and display. At the same time, up to three ComEx shells can be combined for use according to your needs. The size of the wire lead-in head can be M20x1.5 or M25x1.5. The material can be plastic or metal. The plastic lead-in head is directly screwed to fix, no need to tighten the nut. The metal lead-in head is fixed by a metal ground plate in the box. One operation column can have at most two M20 lead-in heads. In order to facilitate on-site operation, each plastic enclosure is equipped with a number plate.
