D4E-2B21N Omron

Small Sealed Switch D4E- N CSM D4E- N DS E 4 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 terminals are also available). 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. Be sure to read Safety Precautions on page 9 to 10 and Safety Precautions for All Limit Switches.
