617193

The 617193 coil is produced by Vickers within the Vickers Hydraulic Accessories series. It serves as an electromagnetic actuator for hydraulic valves, converting electrical energy at 110 VAC into magnetic force that shifts valve spools in automation circuits. Its encapsulated coil construction isolates the winding from hydraulic fluid and airborne contaminants. The encapsulation follows Class F thermal limits, allowing the material to withstand continuous temperature rises typical in embedded industrial manifolds. The coil is designed for 50 Hz mains supplies so it integrates with standard plant power without additional converters.

The winding itself meets Class H insulation requirements, providing higher dielectric strength for occasional overload conditions. A duty factor of ED = 100% confirms that the coil can remain energized continuously without exceeding its thermal rating, which is important for valves that hold a position for long periods. An IP65 ingress protection rating seals the housing against dust and low-pressure water jets, allowing installation near hydraulic presses that generate spray. Electrical performance remains stable down to 90% of the rated voltage, so control cabinets can tolerate modest supply dips while still actuating the connected valve.
