Danfoss 042N7520 Coil

The Danfoss 042N7520 is a high-performance solenoid valve coil engineered for precise control in commercial refrigeration and air conditioning systems. This model is a 24V AC 50/60Hz coil with a 9-watt power consumption, designed for the "Clip-On" fastening system which ensures fast, tool-free mounting and prevents moisture ingress at the armature. Built with Class H insulation, this coil is rated for high ambient temperatures and demanding duty cycles, common in HVACR valve replacement scenarios. It features an IP65 protection rating when used with a DIN plug, making it suitable for environments with high humidity or frequent wash-downs. The Danfoss solenoid coil 042N7520 is compatible with a wide range of Danfoss EVR, EVRA, and EVRAT valves, providing reliable electromagnetic actuation for liquid, suction, and hot gas lines without risking overheating or premature fatigue under standard industrial voltage fluctuations.

• Easy Installation: The Clip-On design allows for secure attachment to the valve armature without requiring secondary mounting hardware.
• High Thermal Stability: Class H insulation allows the winding to withstand temperatures up to 180°C, ensuring longevity in high-heat mechanical rooms.
• Universal Frequency: Rated for both 50Hz and 60Hz, making it a versatile service part for various regional power standards.
• Tight Seal: Integrated O-ring sealing prevents moisture from entering the coil windings, a common cause of solenoid coil failure.

What is the enclosure rating for the Danfoss 042N7520?

This coil achieves an IP65 rating, provided it is installed with a correctly specified DIN 43650-A cable plug. This ensures protection against dust and low-pressure water jets.

Is the 042N7520 compatible with older Danfoss EVR valves?

Yes, as long as the valve utilizes the 13.5mm diameter armature, this Danfoss 24V coil will function as a direct drop-in replacement for the older 042N series.

Can this coil be used on DC circuits?

No, the 042N7520 is strictly an AC solenoid coil. Attempting to run this on a DC power supply will cause immediate overheating and coil burnout.
