Coils

Danfoss Coils have been designed to provide industry leading environmental protection and solenoid performance in a compact and rugged package. Coils with integrated connectors are rated from IP65 up to IP69K environmental protection. Danfoss coils are available with a variety of popular integrated connection options and with wire leads. The best in class, one-piece, shell encapsulated, design meets the most stringent environmental requirements for mobile and industrial applications. The exclusive compact coil design from Danfoss, offers the advantage of field retrofit ability on all existing, and new, applications.

Toughcoil and Large Toughcoils

Toughcoils and Large Toughcoils meet an environmental rating of up to IP69K, depending on the connector chosen. An IP69K rating validates product with high-pressure jet streams, high liquid temperatures and underwater submersion. IP69K protection is standard on coils with MetriPac or Deutsch, integrated connectors. Toughcoils have been qualified to withstand the toughest Mobile Equipment “Thermal Shock Dunk” tests. Toughcoils are available for most 8, 10, 12, 16 and 20 series valves.

C13 and C16

The coil/tube joint is sealed by o-rings preventing fluid ingress and the possibility of tube corrosion. Different electrical connectors offer different levels of protection the minimum being the DIN 43650 connector with a gasket at IP65. The coil winding is copper magnet wire insulation equivalent to class N (200°C). The coil is rated for continuous operation at nominal voltage +/- 10% and an ambient range of -30 to +155°C. For AC voltage an ISO4400 rectified connector must be used, as the coils are wound for DC.

Corrosion Resistance

Developed with renewable energy applications in mind, this plating has been engineered to surpass the ISO 12944-2 requirements for use in C4H level corrosive exterior atmospheres. It allows coils to operate for a significantly longer period of time in outdoor, harsh weather, high humidity environments. In neutral salt spray tests conducted to ASTM B117 and ISO 9227 standards, the Zinc Nickel plating will go 1000 hours before showing any signs of rust or corrosion. Contact your Danfoss representative to inquire about 1000+ hour zinc nickel plating options.
