Omron D4E-1A10N Limit Switch
Omron D4E-1A10N is a general-load limit switch with an 11 mm dia. × 4.7 mm stainless sintered-alloy roller plunger. It uses SPDT contacts and a snap-action mechanism, operates at 50/60 Hz, and carries IP67 protection. Maximum contact resistance is 15 mΩ, while mechanical durability is ten million operations minimum. The D4E-1A10N Snap-Action Roller Plunger belongs to the D4E-N Series within the Omron Snap-Action Plunger Switch Range from Omron D4E-N Product Range. Its roller dimensions, stainless sintered-alloy construction, SPDT contacts, snap action, general-load classification, and IP67 protection define this model.

The Omron D4E-1A10N Limit Switch uses an 11 mm dia. × 4.7 mm stainless sintered-alloy roller plunger with an SPDT contact form and snap-action mechanism. It is classified for general load and operates at 50/60 Hz. Maximum inrush current is 10 A for NC and 10 A for NO. Maximum contact resistance is 15 mΩ, while IP67 protection is specified. Electrical durability is five million operations minimum under the source-stated 10 mA at 24 VDC condition, and mechanical durability is ten million operations minimum. Operating temperature ranges from -10 to 80°C, with relative humidity from 35 to 95%.
Destructive shock resistance is listed at 1,000 m/s² and malfunction shock resistance at 300 m/s². The source does not append max. or min. wording to these shock values, so none is added. The 10 mA at 24 VDC value appears only within the electrical-durability condition and is not presented as a normal load rating. The structured row also does not provide insulation resistance, operating speed, operation frequency, conduit, or mounting details. The strongest model terms are D4E-N Series, roller plunger, 11 × 4.7 mm stainless sintered-alloy roller, SPDT contacts, snap action, general load, 15 mΩ contact resistance, IP67, and ten-million-operation mechanical durability.
