Vickers 300AA Series Solenoid Coil | 300AA00081A 300AA00096A 300AA00125A

The Vickers 300 & 300AA Series coils from LIC Hydraulic are engineered for maximum reliability in solenoid-operated directional control valves. Supporting critical models such as 300AA00081A, 300AA00096A, and 300AA00125A, these coils provide the essential magnetic force required for precise valve shifting. We guarantee 100% mechanical and electrical interchangeability and subject every unit to 100% dielectric strength and resistance consistency testing, ensuring professional performance in high-duty cycle industrial applications.

Technical Configuration Details

• Voltage Options: 24V DC (00081A), 110V/120V AC (00096A), and various specialized AC/DC ratings.

• Insulation Class: Class H ($180\text{°C}$) standard, offering superior thermal endurance.

• Connector Types: DIN 43650 (ISO 4400), Lead wires, or Deutsch options depending on the model.

• Duty Cycle: 100% Continuous Rating.

Key Technical Advantages

• High-Performance Encapsulation: The coils are thermoset-molded with high-grade synthetic resins, providing excellent heat dissipation and physical protection against oil, chemicals, and mechanical shock.

• Thermal Resilience: Designed to operate under extreme temperature conditions without loss of magnetic flux, preventing “valve sticking” caused by coil weakening.

• Precision Winding: Computer-controlled winding ensures exact resistance values, leading to synchronized response times across multi-valve manifolds.

• System Protection: Optimized inductance characteristics help minimize electrical noise and spikes, safeguarding sensitive electronic controllers and PLC outputs.

Application Areas

• Industrial Automation: Injection molding machines, hydraulic presses, and assembly lines.

• Material Handling: Lift tables, dock levelers, and automated storage systems.

• Marine & Offshore: Deck machinery and hydraulic steering controls requiring corrosion-resistant components.

Expert Maintenance Tips

• No Dry Firing: Never energize a solenoid coil unless it is properly installed on the valve’s armature tube. Without the iron core to provide inductance, the coil will overheat and burn out almost instantly.

• Verify Connector Sealing: Ensure the connector gasket is in place and the retaining screw is tightened. Ingress of moisture or hydraulic fluid into the terminal pins is the primary cause of premature coil failure.

• Temperature Monitoring: If a coil feels excessively hot to the touch (above $90\text{–}100\text{°C}$ surface temp), check for over-voltage or mechanical binding of the valve spool, which forces the coil to work harder against resistance.
