The Modlink MSDD interface system makes it easy to access controls in the cabinet for in-plant or machinery diagnostics and servicing. It allows the cabinet to remain closed, and the components inside can continue to operate with their required levels of protection. It is available in both a single and double frame size with a transparent, silver or fiberglass-reinforced gray cover. The cover comes with a choice of locking mechanism—either a 3-mm double-bit key or a knob. Both help the cover and frame to meet IP65 requirements. The two-part system is based on frames and inserts and offers more than 4,000 combinations.
