Omron D4A-3107-VN Limit Switch
Omron D4A-3107-VN is a general-purpose limit switch with a vertical side roller plunger and snap-action mechanism for machine position detection. The 11 mm × 5 mm stainless steel roller suits moving parts that pass across the actuator, while the SPST-NO/SPST-NC contact arrangement provides separate switching paths for control circuits. High inrush capability supports general loads, and IP67 with multiple NEMA enclosure ratings supports protected machine installations. The D4A-3107-VN belongs to the D4A Series within the side roller plunger limit switch range from Omron industrial control products for machine travel, position, and end-of-stroke sensing where lateral roller contact and snap-action switching are needed.

The Omron D4A-3107-VN Limit Switch uses a vertical side roller plunger with an 11 mm × 5 mm stainless steel roller for machine position detection. The side-mounted actuator suits moving parts that pass laterally across the roller, while the snap-action mechanism provides a defined switching response. Its SPST-NO/SPST-NC contact arrangement provides separate normally open and normally closed paths for control circuits. Inrush current capability reaches 30 A maximum on the NC side and 20 A maximum on the NO side. IP67 protection together with multiple NEMA enclosure ratings supports protected machine installations.
Electrical durability is specified at 1 million operations minimum at 10 A, 125 VAC, supporting repeated general-load switching. Initial contact resistance is 25 mΩ maximum. The D4A-3107-VN operates from -20 to 100°C with 35 to 95% relative humidity. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics suit lateral position and travel detection where a side roller plunger, snap-action response, and separate NO/NC switching paths are required. The vertical roller arrangement is the key actuator distinction within this configuration. For a related D4A model using a top plunger instead of a side roller, see the D4A-3109N model.
