Extremely rugged solution with insulation

The incremental, hollow shaft encoders FGHJ 5 are ideally suitable for use on inverter-controlled drives where shaft currents are a concern. Amongst others, applications are found in mining operations where they can be installed between the motor and fan to save space. The connection technology is accommodated in an external terminal box. The extremely rugged encoders offer a hollow shaft diameter of 40 millimeters and a stable, ribbed aluminium housing.

Device options
  • FOC: Encoder signals transmitted via a fiber optic cable
  • 90: Second pulse track as basic track, however, electrically phase shifted by 90°
  • N/N2: Mechanically fixed reference pulse (N), one square-wave pulse per revolution, with inverted signal
  • G: Additional inverted output signals for basic track, 90° track, reference pulse including LED indication
  • 2F: Twice as many basic track pulses by combining the 0° and 90° tracks
  • B: Rapid direction of rotation sensing at each edge of 0° and 90° tracks
  • B2: Rapid direction of rotation sensing at each edge of 0° and 90° tracks; additional standstill detection
  • V: Electronic doubling of the basic track and 90° track pulses through multiple evaluation
  • L2: 150 mA power output for basic track, 90° track and their associated inverted signals
  • J: Optically adjusted pulse disk for reduced rotational frequency modulation
Mechanical options
  • B14 flange for attachments
  • Torque bracket (on request)
