EMKA understands that the basic rule for all control cabinets is that the components inside, especially sensitive electronic components, must be protected. However, there are significant differences, especially in the locking systems used. When special customer requirements have to be met on large cabinets, standardized locking systems sometimes reach their limits.

However, EMKA’s slim multi-point locking systems often offer the right solution, allowing the locking mechanism to free up space on the door. This allows for additional internal clearance, while providing exceptional closing capabilities.

Andy Billingham – MD at EMKA UK points out: “Control cabinets are available in different shapes and designs, ranging from single cabinets to in-line cabinets or double door cabinets. All are available for interior and exterior applications.

“Environmental conditions and individual requirements significantly affect the choice of materials and the final cabinet design. But the cabinet alone does not adequately protect internal components and electronics.

He explains: “The lock and hinge solution is much more critical if the cabinet door is expected to be airtight and, if necessary, must withstand high pressure or meet other security requirements.

“In order to find the most suitable closing and hinge solution, environmental influences and the place of installation are also decisive. While the enclosures used outdoors are mostly plastic and powder coated steel, the material of choice is still stainless steel for very special applications.

“The locking components must be made of the same material, regardless of the material selected. In addition, high requirements for waterproofing and vandalism prevention may have to be met in outdoor applications using, for example, protection class IP65 and safety standards according to resistance classes.

EMKA engineers have established that when designing control cabinets, a distinction is made between closures inside and outside the door seal. Locks inside the door seal are installed on interior doors, and often on the exterior. For example, a swing handle can be mounted on the door, which drives two locking bars inside the door – using a drive or a locking cam.

These systems compress the door seal and ensure a secure closure. EMKA has developed a unique compression lock system with multiple locking for locks inside the door seal. If you use a rotational movement of a compression latch of just 90° – typically 180° – the door closes at multiple latch points, which pulls the entire door evenly into the door seal even if the internal pressure is high.

Alternatively, the lock can be placed on the outside of the seal so that, for example, no components protrude inside the cabinet, the locking bars on the inside of the door are pushed into locking points. latches mounted on the door frame with the door closed using a swing handle or lift handle.

The design of control cabinets demands the highest security requirements for interlocking components. For example, the EMKA locking system specialists were asked to design an attractive swing handle with resistance class RC2 for outdoor control cabinets for the Dutch IT systems company Tecnolimit. This handle is easy to use and can be monitored electronically.
