[. . . ] Safety-door Switch D4NS Multi-contact, Labor-saving, Environment-friendly, Next-generation Safety-door Switch · Lineup includes three contact models with 2NC/1NC and 3NC contact forms in addition to the previous contact forms 1NC/1NO, and 2NC. · M12-connector models are available, saving on labor and simplifying replacement. · Standardized gold-clad contacts provide high contact reliability. · Applicable to both standard loads and micro loads. [. . . ] When using the switch with EN rating, use 10 A fuse, type gI or gG that complies with IEC 60269. · Keep the electrical load below the rated value. · On the switching of general loads (250VAC/3A), do not operate two circuits or more at the same time. Otherwise, insulation performance may be degraded. · The durability of the switch is seriously affected by operating conditions. Evaluate the switch under actual working conditions before permanent installation. · Please mention in machine manufacturer's Instruction. Manual that the user must not repair nor maintain the switch and must contact machine manufacturer for them. · Do not use the switch as a stopper. Be sure to install a stopper as shown in the following illustration to prevent the edge of the operation key from inadvertently hitting the switch directly.
