Motor feedback systems rotary incremental

VFS60 - robust, versatile and perfected for asynchronous motors

Your Benefits

  • Programmable version for a reduced product variety
  • Various programming tools designed to take into account your own programming requirements
  • High performance and reliability even in rough ambient conditions
  • High vibration resistance and extended temperature range through nickel code disk
  • Large ball bearing distances reduce uneven wear and minimize vibration on the motor feedback housing, which increases the motor feedback system’s service life
  • The “insulated shaft connection” prevents electrical continuity through the bearings of the motor feedback system, thus extending the operating life of the system


VFS60 - robust, versatile and perfected for asynchronous motors

Motor feedback systems from the VFS60 product family are ideally suited for use in industrial applications under rough conditions, especially for attaching to asynchronous motors. A large number of product variants meets almost all requirements: with through hollow shaft or blind hollow shaft of 8 mm to 15 mm diameter, with plug-in cable connection or pre-assembled male connector at the cable end. This means more mechanical flexibility. In addition, the robust shaft bearing increases the service life while at the same time reducing the servicing and maintenance requirements. The increased bearing distance guarantees a previously unattainable low level of vibration and optimum concentricity, even at maximum operating speed. The product families are allocated to different performance classes. From different defined line counts to a pre-programmed version. Moreover, all the common electrical interfaces are available. TTL, HTL or sine 0.5Vss.

At a glance
  • TTL, HTL or sine 0.5 Vpp interfaces
  • Resolution of up to 65,536 lines per revolution
  • Individual programming of the interface, line count and of the zero pulse
  • Direct programming via RS485
  • Excellent concentricity through large distance between the ball bearings
  • Extremely rugged
  • Protection class IP65
  • Mechanical flexibility through blind hollow shaft and through hollow shafts with diameters of 8 to 15 mm, available with various torque supports
  • Temperature range from –30 °C to +100 °C
  • Insulated shaft connection through plastic collar possible
