guard lock Safety-Door Switch
• Release protective cover locks using controller signals or pushbut-
ton switches after the cutting tool stops moving due to inertia
• A mechanical lock is applied automatically when the Operation
Key is inserted. A high level of safety is achieved using a mecha-
nism where the lock is only released when voltage is applied to the
solenoid.
• Conforms to EN (TÜV) standards corresponding to the CE marking
• Certified by UL, CSA and CCC standards
• The Switch contact is opened by a direct opening mechanism (NC
contacts only) when the protective cover is opened.
Direct opening mechanism that is EN-certified is indicated by
on the Switch
• Auxiliary release key ensures easy maintenance and unlocks the
door in the case of a power failure.
• Tough aluminum die-cast body incorporating a switch box with
degree of protection satisfying IP67, UL, and CSA TYPE6P, 13
• Equipped with a horizontal and vertical conduit opening
• Models incorporating easy-to-see indicators for monitoring and
those using an adjustable Operation Key for a swinging door are
available
• The mounting direction of the head can be changed to allow the
Operation Key to be inserted from four directions
