Purchase now — Atlantechdrives provides you the UF3-24VDC-1, a high-durability electromagnetic solenoid coil designed by Kuhnke for precision pneumatic and hydraulic valve actuation. This 24V DC component is engineered to provide decisive switching force and high magnetic flux density for sophisticated automated fluid systems.
What Is the UF3-24VDC-1?
The UF3-24VDC-1 is a professional-grade DC-rated solenoid coil from Kuhnke’s UF series, specifically wound for the 24V DC standard common in global industrial automation. This coil is characterized by its high-quality copper windings and advanced resin encapsulation, which protects the sensitive electrical components from industrial contaminants, moisture, and thermal stress. The UF series is renowned for its volumetric efficiency and low power consumption, allowing for dense manifold mounting without excessive heat accumulation in control cabinets. When energized, the UF3-24VDC-1 generates a stable magnetic field that decisively pulls the valve armature, ensuring consistent switching performance even under high-cycle industrial operations. Its design features a standardized industrial interface (typically Form B or C) for rapid electrical connection and is fully rated for 100% continuous duty (ED). This allows the coil to remain energized indefinitely without risk of thermal runaway, making it an ideal choice for 24/7 production lines in the automotive and pharmaceutical sectors.

Applications and System Architecture
The UF3-24VDC-1 is predominantly used in the control panels of assembly lines, robotic grippers, and automated sorting machines. In a standard architecture, it serves as the final actuator for directional control valves, managed directly by the 24VDC digital outputs of a PLC. Its use of direct current provides a cleaner and more stable actuation than AC equivalents, reducing mechanical wear on the valve armature. The coil’s robust construction ensures that it can withstand the electrical noise and vibration common in proximity to heavy industrial drives. By utilizing the genuine Kuhnke UF3 series, system integrators ensure perfect mechanical fitment with the valve stem, preventing the «armature buzz» and premature failure often associated with low-quality generic replacement coils.
Installation Advice
When installing the UF3-24VDC-1, it is paramount that the coil is never energized while it is removed from the valve stem; without the iron core to provide inductance, the coil will rapidly overheat and burn out within seconds. We recommend using a connector with a built-in suppression diode or varistor to protect the PLC outputs from the inductive flyback voltage generated during de-energization. Additionally, ensure the mounting nut is tightened just enough to prevent vibration-induced movement; over-tightening can crack the resin housing and compromise the seal. In wash-down environments, verify that the gasket between the plug and the coil is correctly seated to maintain the IP65 rating.
Frequently Asked Questions
Q: Can the UF3-24VDC-1 be used on a 24VAC circuit?
A: No, this is a DC-specific coil. Using it with an AC supply will cause excessive current draw and lead to permanent failure of the component due to impedance mismatch.
Q: Is this coil compatible with other Kuhnke series?
A: The UF3 series has specific internal diameters; while it may look similar to others, always verify the valve stem diameter and series compatibility before installation to ensure proper magnetic coupling.
