User manual OMRON D4NH DATASHEET

[. . . ] Miniature Safety-door Hinge Switch D4NH New series Safety-door Hinge Switch Designed for sace saving guaring in Machines and safety Equipment · Lineup includes three contact models with 2NC/1NO and 3NC contacts in addition to the 1NC/1NO, and 2NC versions. Version with MBB contacts meet applications for avdanced requirements. · M12-connector models are available, saving on labor and simplifying maintenance. · Standardized gold-clad contacts provide high contact reliability Can be used with both standard loads and microloads. [. . . ] · Do not attempt to disassemble or modify the Switch. Doing so may cause the Switch to malfunction. · Do not use the Switch where explosive gas, flammable gas, or any other hazardous gas may be present. · Install the Switch in a location away from close body contact. · Do not use the Switch submerged in oil or water, or in locations continuously subject to splashes of oil or water. Doing so may result in oil or water entering the Switch interior. (The IP67 degree of protection specification for the Switch refers to water penetration while the Switch is submersed in water for a specified period of time. ) · Protect the head from foreign material. Subjecting the head to foreign material may result in premature wear or damage to the Switch. Although the switch body is protected from penetration by dust or water, the head is not protected from penetration by minute particles or water. · Turn the power OFF before wiring. Not doing so may result in electric shock. · Connect a fuse to the Switch in series to protect the Switch from short-circuit damage. Use a fuse with a breaking current 1. 5 to 2 times larger than the rated current. To conform to EN ratings, use an IEC60269-compliant 10-A fuse type gI or gG. · Do not switch circuits for two or more standard loads (250 VAC, 3 A) at the same time. Doing so may adversely affect insulation performance. · The durability of the Switch is greatly affected by operating conditions. Evaluate the Switch under actual working conditions before permanent installation and use within a number of switching operations that will not adversely affect the Switch's performance. · Be sure to indicate in the machine manufacturer's instruction manual that the user must not attempt to repair or maintain the Switch and must contact the machine manufacturer for any repairs or maintenance. · If the Switch is to be used in an emergency stop circuit or in a safety circuit for preventing accidents resulting in injuries or deaths, use a model that has an NC contact equipped with a direct opening mechanism and make sure that the Switch operates in the direct opening mode. Switch Mounting · Mount the Switch using M4 screws and washers and tighten the screws to the specified torque. · For safety, use screws that cannot be easily removed, or use an equivalent measure to ensure that the Switch is secure. · Secure the Switch with two M4 bolts and washers. [. . . ] Design the circuit so that no error signal will be generated. Use or set a Switch that is operated in one direction only. Use LAPP connectors together with seal packing (JPK-16, GP-13. 5, GPM20, or GPM12), and tighten to the specified tightening torque. Ohm Denki is a Japanese manufacturer.
