The Omron D4V-8166Z Limit Switch uses a coil spring actuator. The supplied row lists an operating-speed range of 5 mm to 0.5 m/s, mechanical operation frequency of 120 operations per minute, and electrical operation frequency of 30 operations per minute. Initial contact resistance is 25 mΩ maximum, insulation resistance is 100 MΩ minimum at 500 VDC, and rated insulation voltage is 250 V. IP65 protection is specified. Mechanical durability is ten million operations minimum. Electrical durability is 300,000 operations minimum under the stated 5 A at 250 VAC resistive-load condition, which is treated as a durability test condition rather than an independent normal load rating.
Operating temperature ranges from -20 to 60°C with no icing, and humidity is 90% maximum. Malfunction vibration resistance is 10 to 55 Hz at 1.5 mm double amplitude. Destructive shock resistance is 1,000 m/s² minimum at the free position, while malfunction shock resistance is 300 m/s² minimum at the operation-limit position. Dielectric strength is 1,000 VAC at 50/60 Hz for one minute between terminals of the same polarity and 1,500 VAC between current-carrying metal parts and ground. The strongest model terms are coil spring actuator, D4V Series, stated speed range, IP65, 25 mΩ contact resistance, 250 V insulation rating, and ten-million-operation mechanical durability.
