Safety Interlock Switches D4BL D4BL Guard Lock Safety-Door Switch G * Release protective cover locks using controller signals or pushbutton 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 mechanism where the lock is only released when voltage is applied to the solenoid. * Conforms to EN (TUV) 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 S Specifications Standards and EC Directives Certified Standard Ratings Conforms to the following EC Directives: * Machinery Directive * Low Voltage Directive * EN 1088 TUV (EN 60947-5-1), CCC (GB14048.5) Item Utilization category Certified Standards Standard Model Indicator Model AC-15 AC-15 Rated operating current (Ie) 3A 6A Rated operating voltage (Ue) 250 V 115 V Certification body Standard File No. Note: Use a 10 A fuse type gI or gG that conforms to IEC 60269 as a shortcircuit protection device.
