Omron D4B-2115N Limit Switch
Omron D4B-2115N is a heavy-duty limit switch with a stainless steel roller lever for machine position and end-of-travel detection. Its snap-action mechanism and 1NC/1NO contact arrangement provide defined switching for industrial control circuits, while the roller lever supports smooth actuation from cams and moving machine parts. A G1/2 conduit entry supports field wiring, and IP67 protection with a -40 to 80°C operating range suits demanding machinery environments. The D4B-2115N belongs to the D4B-N Series within the heavy-duty roller lever limit switch range from Omron machine safety products for robust industrial position sensing.

The Omron D4B-2115N Limit Switch uses a stainless steel roller lever actuator with a snap-action operating mechanism for reliable machine position and end-of-travel detection. The roller lever supports smooth actuation from moving cams and machine parts, while the 1NC/1NO contact configuration provides separate normally closed and normally open switching paths. Operating speed ranges from 1 mm/s to 0.5 m/s, with up to 120 mechanical operations per minute and 30 electrical operations per minute. A G1/2 conduit opening supports field wiring. IP67 protection and an ambient operating range from -40 to 80°C suit demanding industrial machinery.
Rated insulation voltage is 600 V, initial contact resistance is 25 mΩ maximum, and insulation resistance is 100 MΩ minimum. The D4B-2115N withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 0.75 mm single amplitude. The snap-action contact gap is specified at 2 × 0.5 mm minimum, helping define the switching characteristics of this configuration. These features combine heavy-duty roller-lever actuation, wide temperature capability, sealed construction, and defined 1NC/1NO switching for industrial position control over time.
