Juli 2005 5:48 17 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 replace- ment. Standardized gold-clad contacts provide high contact reliability. Applicable to both standard loads and micro loads. Free of lead, cadmium, and hexavalent chrome, reducing the burden on the en- vironment. Model Number Structure Model Number Legend Switch Operation Key D4NS- D4DS-K 12 3 1 1.
