Omron D4E-2G20N Limit Switch
Omron D4E-2G20N is the microload roller lever option in this D4E-N group, using a 9.5 mm × 4 mm stainless sintered alloy roller with SPDT switching. The lever format gives a wider mechanical approach path than a straight plunger, while IP67 protection and 10 million minimum mechanical operations support repeated position sensing. Contact resistance is specified at 15 mΩ maximum and insulation resistance at 100 MΩ minimum. The D4E-2G20N is part of the D4E-N Series within the microload roller lever switch range from Omron control products.

The Omron D4E-2G20N Limit Switch combines microload operation with a 9.5 mm × 4 mm stainless sintered alloy roller lever and SPDT contacts. The lever actuator offers a different target approach geometry from roller plungers, allowing mechanical motion to be transferred through the lever. The source specifies 50/60 Hz operation, a temperature range of -10 to 80°C, and relative humidity from 35 to 95%. Pollution degree 3 according to EN60947-5-1 is listed, along with IP67 protection, 15 mΩ maximum contact resistance, and 100 MΩ minimum insulation resistance at 500 VDC.
Mechanical durability is specified at 10 million operations minimum. Shock resistance reaches 1,000 m/s² for destruction and 300 m/s² for malfunction. The row does not provide a separate rated microload current or electrical durability value, so those specifications are intentionally omitted rather than inferred. Its selection is therefore driven mainly by the microload designation and roller-lever actuator geometry. For a D4E-N roller lever with the same 9.5 mm × 4 mm roller dimensions and a stated 1 A at 30 VDC rating, see the D4E-1G10N model.
