Omron D4E-1B10N Limit Switch
Omron D4E-1B10N combines a cross roller plunger with SPDT switching for directional position sensing at 30 VDC. The actuator uses an 11 mm × 4.7 mm stainless sintered alloy roller, while the rated load is 1 A at 30 VDC. IP67 protection, 15 mΩ maximum contact resistance, and 5 million minimum electrical operations at 10 mA, 24 VDC are specified. The D4E-1B10N belongs to the D4E-N Series within the cross roller plunger limit switch range from Omron switching components. The cross-roller actuator is its main selection difference from direct plunger versions.

The Omron D4E-1B10N Limit Switch uses an 11 mm × 4.7 mm cross roller plunger made from stainless sintered alloy. Its SPDT contact arrangement is rated at 1 A at 30 VDC, with 10 A maximum inrush specified for both NC and NO contacts. The cross-roller orientation is designed for directional mechanical contact across the actuator and is therefore the main difference from standard roller-plunger or straight-plunger D4E-N models. IP67 protection is specified, together with operation from -10 to 80°C and relative humidity from 35 to 95%. Initial contact resistance is 15 mΩ maximum.
Electrical durability reaches 5 million operations minimum at 10 mA, 24 VDC, while mechanical durability is specified at 10 million operations minimum. Destructive shock resistance is 1,000 m/s² and malfunction shock resistance is 300 m/s². These values, together with the 30 VDC rating, make this model especially identifiable by its cross-roller geometry and high-cycle low-current switching specification. For a D4E-N model using a straight stainless steel plunger with the same stated 1 A at 30 VDC rating, see the D4E-1C10N model.
