Cartridge Valve Coil tolerates high temperatures.
May 12, 2006 -
Designed for off-highway vehicle OEMs, compact valve coil features protective layer of encapsulated plastic under solid metal frame. It tolerates voltage extremes and withstands fluid ingression due to power spray or submersion in water, mud, or snow. IP69K environmental protection rated product is suited for asphalt machinery, agricultural equipment with chemical and power wash exposure, and snow plows and salt spreading machines.

Water, Mud, and Snow - New Cartridge Valve Coil Promises to Stand the Test
April 11, 2006
AMES, IOWA, USA - SAUER-DANFOSS INC. (NYSE:SHS) Sauer-Danfoss has introduced a new valve coil that will help OEMs increase service intervals and overall machine life. Some valve coils, currently available on the market, may fail when exposed to over-voltage, excessive heat, or water for extended periods of time. This is not the case with the Sauer-Danfoss coil. Specifically designed for the harsh off-highway environment, the coil tolerates very high temperatures and voltage extremes. It also withstands fluid ingression due to power spray or submersion in water, mud, or snow.
The coil is designed with a protective layer of encapsulated plastic with a solid metal frame around it. A special molding technique prevents moisture build-up while the plastic is applied and because the metal cover is placed outside the plastic, the coil resists even dramatic temperature changes. The design process results in a very high level of chemical and environmental resistance. An o-ring seal, for example, is unnecessary. Also, the coil has passed a range of environmental tests, including a high-pressure spray test, a shock and vibration test, a thermal shock and dunk test, a salt fog test, a chemical spray test, and a combined temperature, humidity, and voltage test. It has an IP69K environmental protection rating and a -40◦C to +71◦C [-40◦ F to 160◦ F] ambient temperature rating for continuous duty operation. Finally, the input voltage tolerance spans from 75 % to 133 % of nominal. Ideal applications include asphalt machinery, agricultural equipment with chemical and power wash exposure, and snow plows and salt spreading machines.
"Designing this coil, we wanted to target applications that operate under conditions that are particularly demanding for the components," says Dave Wohlsdorf, Product Portfolio Manager, Sauer-Danfoss, Ames, USA. "Some agricultural and road maintenance applications experience down-time because the components used are not always designed to handle exposure to water, chemicals, excessive temperatures, continuous vibrations and so on. For the OEM or end-user, though, down-time is down-time. It costs money no matter what the reason. Our coil may not be the most noticeable part of an application, but it does a very important job. It helps prevent vehicle down-time, thereby saving time and money for OEMs and end-users alike."
Featuring a very compact design, the Sauer-Danfoss coil is smaller than most competing products, thereby leaving more space for other components on the application. The compact design makes it possible to fit the cartridge valves closer together in the vehicle HIC (Hydraulic Integrated Circuit) block(s). For the OEM, this means reduced installation time and added design flexibility. The coil is available with three different electrical connectors - Deutsch DT04-2P, Metri-Pak 150 Series Type 1, and 18" lead wires. All connectors are available with optional integral diodes and the finished coils are color coded for easy voltage identification.
The coil was developed by an international team of engineers from Sauer-Danfoss locations in Reggio Emilia, Italy; Easley, South Carolina, USA; and Ames, Iowa, USA. Sauer-Danfoss serves off-highway vehicle OEMs around the world and often takes an international approach to product development. Wohlsdorf puts it this way: "Many of our customers are international OEMs that operate on a world-wide basis. Taking an international approach is often the best way to secure that a product will work well in different areas, different applications, and under different operating conditions."
