Hengstler Resolver R25 Series | Descriptions

Brushless resolvers are the ideal rotor position indicators for the position feedback of brushless motors, robots or direct drives. They are robust, reliable, and suitable for high operating temperatures until 155 °C and resistant to most process liquids, contaminations, radiation, and EMC-Interferences as well as highly shock-proof and vibration-resistant.

R25 series industry resolvers possess especially robust casings with protection class IP65. They are especially suitable for use with high temperatures (+125 °C in long-term operation), and offer extraordinary values of vibration and shock resistance (40g as well as 200g), as well as noise immunity. The user is flexible in the application because of the corrosion-resistant versions for integration or extension, the connection could easily be done by Standard MS style connectors. The accuracy has a spread of ± 7 up to ± 200 arc-minutes.
