Omron D4E-1A00N Limit Switch
Omron D4E-1A00N is a snap-action limit switch with an 11 mm × 4.7 mm stainless sintered alloy roller plunger and SPDT contacts. The rolling actuator provides the mechanical contact point, while NC and NO inrush current are both specified at 10 A maximum. IP67 protection, 15 mΩ maximum contact resistance, and 10 million minimum mechanical operations are listed for this model. The D4E-1A00N is part of the D4E-N Series within the snap-action roller plunger switch range from Omron limit switch products. Its standard roller-plunger format distinguishes it from cross-roller and straight-plunger versions.

| Operating Mechanism | Snap action |
The Omron D4E-1A00N Limit Switch uses an 11 mm × 4.7 mm stainless sintered alloy roller plunger with a snap-action mechanism and SPDT contact arrangement. The rolling actuator provides the mechanical interface for targets moving across the switch, while snap action gives a defined contact change once the operating point is reached. The source specifies 10 A maximum inrush current for both NC and NO contacts. IP67 protection is listed, along with operation from -10 to 80°C and relative humidity between 35 and 95%. Initial contact resistance is 15 mΩ maximum.
Mechanical durability is specified at 10 million operations minimum, and electrical durability is listed at 500,000 operations minimum at 5 A, 250 VAC. Destructive shock resistance reaches 1,000 m/s², while malfunction shock resistance is 300 m/s². The standard roller-plunger geometry and snap-action mechanism are the main points that separate the D4E-1A00N from cross-roller and direct-plunger versions. For a related D4E-N configuration using a cross roller plunger, compare the D4E-1B10N model.
