Small Sealed Switch D4E-@N CSM_D4E-_N_DS_E_6_1 Slim and Compact Switch with Better Seal and Ensuring Longer Service Life than D4E • Flat springs with an improved lever ratio of the built-in switch ensure smooth snap action and long life expectancy. • Protection cover protects the built-in switch from dust and oil. Plunger incorporates a tough seal cap that lasts for a long time. • One touch connector eliminates need for tedious wiring operations and reduces downtime for wiring and maintenance (models with standard, easy-to-use screw For the most recent information on models that have been certified for terminals are also available). safety standards, refer to your OMRON website. • Minute load model with gold cladding is optimal for electronic control. • Molded terminal types as well as molded terminal types with operating indicator lamps are available for screw terminal systems. • Approved by EN, UL, CSA, and CCC (Chinese standard). (Ask your OMRON representative for Information on approved models.) • No difference in mounting pitch and characteristics between D4E-@N and D4E models.
