300AA Solenoid Coil | 300AA00122A 300AA00128A 300AA00134A | 24V DC Cartridge Valve Coil

300AA Series Hydraulic Solenoid Cartridge Valve Coils

Product Overview: The 300AA Series consists of high-performance solenoid coils specifically engineered for screw-in cartridge valves in industrial and mobile hydraulic systems. Designed for demanding environments, these coils utilize a fully encapsulated injection molding process, providing exceptional resistance to water, vibration, and high temperatures. Whether utilized in construction machinery or industrial hydraulic power units, the 300AA series (such as 300AA00122A and 300AA00128A) delivers stable electromagnetic thrust, ensuring consistent spool movement under high-frequency switching.

Featured models: 300AA00122A, 300AA00121A, 300AA00125A, 300AA00128A, 300AA00130A, 300AA00134A, 300AA00278A, and 300AA00375.

Key Technical Advantages:

• Heavy-Duty Encapsulation: Molded with high-temperature synthetic resin to protect internal windings from moisture, corrosion, and vibration-induced open circuits.

• 100% Duty Cycle (ED): Designed for continuous, uninterrupted operation, maintaining stable magnetic output without thermal drift even under sustained loads.

• Precision Voltage Regulation: Standard 24V DC specification with a wide tolerance range, compatible with major mobile power grids and industrial PLC control systems.

• Versatile Connector Options: Available with DIN 43650, Deutsch DT04-2P, or lead-wire interfaces to meet various protection requirements (up to IP69K).
