Order now the Kuhnke IA2-24VDC — Atlantechdrives provides you with this industrial-grade 24VDC solenoid coil from the Kuhnke IA2 series, built for precise and reliable pneumatic valve actuation in continuous-duty industrial automation systems.
What Is the Kuhnke IA2-24VDC?
The IA2-24VDC is a direct-current solenoid coil manufactured by Kuhnke (a Kendrion brand), engineered to actuate directional control valves within the Kuhnke IA2 pneumatic valve series. When energised at 24VDC, the coil generates a focused electromagnetic field that displaces the valve spool or poppet, opening or closing the pneumatic circuit. Operating at 24VDC — the standard control voltage in modern industrial automation — the IA2-24VDC integrates directly with PLC digital outputs, safety relays, and standard control panels without any additional voltage conversion hardware. Kuhnke coils are characterised by their high magnetic efficiency relative to coil volume, their resistance to voltage fluctuations common in industrial environments, and their robust construction rated for continuous energisation at 100% duty cycle. The IA2 series is a widely deployed Kuhnke platform found across European machinery in packaging, automotive, food processing, and general factory automation, making the IA2-24VDC one of the most frequently required spare coils in maintenance stockrooms operating Kuhnke pneumatic systems.

Compatibility and Applications
The Kuhnke IA2-24VDC coil is the correct electrical actuator for the Kuhnke IA2 valve body series. Typical industrial applications include: packaging machinery with high-cycle pneumatic actuation; automotive assembly lines for welding fixtures and press tooling; food and beverage environments with 24VDC control architecture; textile and printing machinery for tension control; and any PLC-controlled pneumatic circuit using Kuhnke IA2 series valves.
Installation Advice
Before replacing or installing the Kuhnke IA2-24VDC coil, always de-energise the 24VDC control circuit and depressurise the pneumatic system. Slide the coil over the valve solenoid stem ensuring correct bore alignment, then secure with the retaining nut tightened to Kuhnke-specified torque — overtightening distorts the coil former and narrows the magnetic air gap. Seat the DIN EN 175301-803 connector firmly and tighten its retaining screw fully to achieve the IP65 seal; a loose connector is the primary cause of moisture ingress and premature coil failure. Verify polarity: DC coils must be connected with correct polarity. After installation, measure supply voltage at the coil terminals under load — a reading below 21.6VDC indicates excessive cable resistance or an undersized supply.
Frequently Asked Questions
Q: Can the IA2-24VDC be energised continuously without a duty cycle timer?
A: Yes. The Kuhnke IA2-24VDC is rated for 100% duty cycle at nominal voltage within the specified ambient temperature range. No external duty cycle control is required. Ensure adequate ventilation around the valve manifold to prevent heat accumulation in tightly packed installations.
Q: The coil gets warm during normal operation — is this a fault?
A: Moderate warmth is normal for a DC solenoid coil at continuous duty. Class F insulation is rated to 155°C winding temperature. If surface temperature exceeds ~70–80°C, check that supply voltage does not exceed 26.4VDC and ambient temperature is within specification. Persistent overheating at correct voltage indicates a mechanical issue such as a sticking valve spool.
Q: Is the IA2-24VDC interchangeable with Kuhnke coils from the IA1 or IA3 series?
A: No. Kuhnke coil models are series-specific. Bore diameter, magnetic gap, and retaining geometry differ between IA1, IA2, and IA3 series. Always match the replacement coil to the series designation on the valve body nameplate.
