HL508174

The HL508174 is an electrical coil accessory produced by Vickers for the Vickers Hydraulic Accessories series, intended to actuate solenoid-operated valves in automated hydraulic circuits. A DIN 43650 (ISO 4400) connector is provided so the coil mates directly with standard industrial valve housings. The coil runs on a 24 V DC supply, and a ±10 % voltage tolerance permits safe operation when the control bus experiences minor voltage drift. Using a DC source simplifies battery-powered or rectified supplies in mobile machines. A continuous 100 % ED duty rating lets the coil remain energized for indefinite periods during sustained valve holds. Power consumption of 18 W defines the electrical load and aids thermal calculations. Class F encapsulation allows the winding insulation to withstand elevated temperatures encountered near hydraulic manifolds.

Ingress protection is rated at IP65 so the unit resists dust and low-pressure water jets often present around hydraulic power units. A storage temperature range of –25 °C to +85 °C ensures the coil can be kept in unconditioned warehouses without damage. The assembly weighs 0.99 lb, which assists designers when estimating manifold mass and support requirements. An overall width of 1.81 in helps confirm clearance when the coil is installed next to adjacent valves or tubing.
