Miniature Safety-door Hinge Switch D4NH Compact, Resin Safety-door Hinge Switch Designed for Saving Space in Machines and Other Equipment Lineu p includes three contact models with 2NC/1NO and 3NC contact forms in addition to the previous contact forms 1NC/ 1NO, and 2NC. Models with MBB contacts are also available. M12-connector models are available, saving on labor and sim- plifying replacement. Standardized gold-clad contacts provide high contact reliability Can be used with both standard loads and microloads. Free of lead, cadmium, and hexavalent chrome, reducing the burden on the environment. Caution Be sure to read the Safety Precautions on page 134.
