Omron D4V-8112Z Limit Switch
Omron D4V-8112Z is a compact enclosed limit switch with a roller plunger for repeatable position detection in industrial machinery. The rolling actuator suits cams, slides, conveyors, and moving workpieces, helping reduce direct sliding contact during frequent switching. Its 5 A at 250 VAC resistive-load capability supports standard machine control circuits, while operation from 5 mm/s to 0.5 m/s covers varied movement speeds. IP65 protection suits normal factory environments. The D4V-8112Z belongs to the D4V Series within the compact roller plunger limit switch range from Omron control products for reliable machine travel and position sensing.

The Omron D4V-8112Z Limit Switch uses a roller plunger actuator for repeatable mechanical position detection in industrial machinery. The rolling contact suits cams, slides, conveyors, and moving workpieces that pass across the actuator, helping reduce direct sliding contact during frequent switching. Operating speed ranges from 5 mm/s to 0.5 m/s, with up to 120 mechanical operations and 30 electrical operations per minute. The switch is specified for 5 A at 250 VAC resistive-load operation. IP65 protection supports normal factory environments, while the -20 to 60°C operating range covers a broad range of machine conditions.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 300,000 operations minimum at 5 A, 250 VAC. Initial contact resistance is 25 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The D4V-8112Z withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s², with vibration resistance from 10 to 55 Hz at 1.5 mm double amplitude. These specifications support high-cycle roller-plunger sensing in compact automation equipment. The roller actuator is the main physical distinction from direct-plunger D4V versions. For a closely related D4V version using a push plunger instead of a roller plunger, see the D4V-8111Z model.
