Application NoticeGeneral– extreme temperature applications– vibration tested (according to MIL-STD810F/Jan2000

Fig. 514.5C-10)– ultra-high vacuum applications

(low outgassing, can be baked out at 240°C)Aerospace– gas turbine starter/generators for aircraft engines– regulation of combustion enginesOil & Gas Industry– oil, gas and geothermal wellsRobotics– robotic exploration vehiclesIndustry– pumps and valves for liquid metal cooling systems/turbine fuel

and steam control– valve adjustment for gas and steam power plants

This motor contains leaded solder. It therefore does not fulfill the requirements for the permitted maximum concentration of hazardous substances in accordance with the EC directive 2011/65/EC (RoHS) for all applications. The motor may there-fore only be used for devices that are not subject to this directive.
