Omron D4V-8111Z Limit Switch
Omron D4V-8111Z is a compact enclosed limit switch with a push plunger actuator for direct position and end-of-travel detection. The straight plunger design suits moving parts that approach the switch head-on, while an operating speed of 5 mm/s to 0.5 m/s supports varied machine movement. Its 5 A at 250 VAC resistive-load capability suits common industrial control circuits, and IP65 protection supports normal factory environments. Long mechanical life makes it suitable for repetitive automation tasks. The D4V-8111Z belongs to the D4V Series within the compact enclosed limit switch range from Omron machine control products for machine position sensing.

The Omron D4V-8111Z Limit Switch uses a push plunger actuator for direct mechanical position and end-of-travel detection in industrial machinery. The straight-line actuator suits applications where a moving component presses the switch from the front, providing a clear switching point for machine stops, slides, and compact automation mechanisms. Operating speed ranges from 5 mm/s to 0.5 m/s, allowing use with both slow and faster moving parts. The switch is designed for 5 A at 250 VAC resistive load and supports up to 120 mechanical operations per minute. IP65 protection helps shield the enclosed mechanism from dust and water encountered in normal factory service.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 300,000 operations minimum at 5 A, 250 VAC resistive load. Initial contact resistance is 25 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The D4V-8111Z operates from -20 to 60°C and withstands destructive shock of at least 1,000 m/s², with malfunction shock resistance of at least 300 m/s². Vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These specifications support repetitive plunger-actuated position sensing in compact automation systems where reliable switching and long service life are important.
