The explosion-proof operating column is a flexible control system that can provide customers with standard or special requirements for local control units or display units. We offer three models of standard housing for three different situations of control and display. At the same time, up to three ComEx enclosures can be combined to use according to your needs. The size of the lead lead can be M20x1.5 or M25x1.5. The material can be plastic or metal. The plastic lead-in is fixed with direct thread and no fastening nut is required. The metal inlet head is secured by a metal floor in the body of the box. One operating column may have up to two M20 lead leads. For ease of field operation, each plastic case is fitted with a number plate.
