Buy now — Atlantechdrives provides you the 76.411.02.12, a high-durability electromagnetic solenoid coil engineered by Kuhnke for precision 12V DC valve actuation. This component is essential for converting electrical control signals into mechanical force to shift pneumatic or hydraulic valve spools in mobile or low-voltage industrial circuits.
What Is the 76.411.02.12?
The 76.411.02.12 is a professional-grade 12V DC-rated solenoid coil from the Kuhnke 76-series, specifically developed for high-frequency switching and reliable pressure maintenance. This coil is characterized by its high-purity copper windings and advanced resin encapsulation, providing a robust barrier against moisture, industrial oils, and thermal fatigue. As the electromagnetic heart of the valve, the 76.411.02.12 generates a stable and powerful magnetic flux that decisively pulls the valve armature, ensuring consistent switching performance even under high-cycle industrial operations. The 12V DC rating is particularly useful for specialized machinery, automotive assembly jigs, or portable pneumatic devices where 24V power is not the primary standard. Kuhnke’s engineering focuses on volumetric efficiency and low power consumption, allowing for dense manifold mounting without excessive heat accumulation in control cabinets. This reliability makes the 76.411.02.12 a critical spare part for maintenance engineers looking to prevent unplanned downtime in sectors where sub-millisecond precision is required for synchronized machine movements.

Applications and Use Cases
The 76.411.02.12 is predominantly used in the semiconductor industry, medical automation, and mobile industrial platforms. In a standard architecture, it serves as the primary actuator for directional valves, managed by a 12V control branch to drive pneumatic cylinders or air-driven motors. Its design allows for direct integration with low-voltage electronic boards and micro-PLCs. The 76 series’ reputation for repeatability makes it the preferred choice for applications requiring constant timing accuracy over millions of cycles. Because it utilizes 12V DC, it is also ideal for integration into testing equipment and portable field instrumentation where voltage stability and low power draw are paramount for operational efficiency.
Maintenance Tips
The most important maintenance rule for the 76.411.02.12 is to never energize the coil 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 periodically inspecting the electrical pins for signs of oxidation or arcing, especially in humid or corrosive environments. Additionally, ensure the 12V DC power supply is regulated; high-frequency noise or significant voltage ripple can cause premature fatigue of the coil insulation. If your application involves high-frequency switching, verify that the ambient temperature remains within the Class F limits to avoid thermal degradation of the technical resins.
Frequently Asked Questions
Q: Can the 76.411.02.12 handle 12V AC power?
A: No, this is a DC-specific coil. Using it with an AC supply will result in excessive current draw and immediate failure of the component due to impedance mismatch.
Q: Does this coil include the electrical plug?
A: Typically, the connector is sold separately to allow for different cable lengths and protection types; however, it is compatible with standard industrial solenoid plugs.
