Omron D4V-8108Z Limit Switch
Omron D4V-8108Z is a compact enclosed limit switch with an adjustable roller lever for flexible machine position and travel detection. The adjustable actuator helps align the sensing point with different target positions, making it useful on conveyors, machine tools, and automated mechanisms where approach paths may vary. Operating speed from 5 mm/s to 0.5 m/s supports varied machine movement, while IP65 protection suits normal factory environments. Long mechanical life supports repeated industrial switching. The D4V-8108Z belongs to the D4V Series within the adjustable roller lever limit switch range from Omron industrial control products for reliable machine position and end-of-travel sensing.

The Omron D4V-8108Z Limit Switch uses an adjustable roller lever for flexible machine position and end-of-travel detection. The adjustable actuator allows the sensing point to be aligned with different target positions, making it useful on conveyors, machine tools, and automated equipment where the approach path or product dimensions can vary. 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, while IP65 protection supports normal industrial environments exposed to dust and water.
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-8108Z operates from -20 to 60°C and withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics suit compact applications that need adjustable roller-lever positioning with long service life. For a related D4V model using a fixed roller lever rather than an adjustable actuator, see the D4V-8104Z model.
