M45NC Incremental Magnetic Encoder

No-contact technology | 45×45 mm aluminum body | Magnetic actuator on hollow shaft Ø4÷10 mm | Resolution from 8 to 2048 pulses/rotation | Bidirectional output with zero (BZ) | Continuous speed up to 30,000 rpm | Maximum frequency response 600 kHz | IP67 protection rating on the shaft side (standard) | Oil and liquid immunity | Line Driver 26LS31, ET7272 and NPN electronics

Incremental magnetic encoder with no contact between the rotating shaft and the transducer body, in a 45×45 mm housing. High degree of protection and immunity to oils and liquids; suitable for high-speed applications (30,000 rpm).

Generates incremental pulses from 8 to 2048 per revolution (multipliable ×4 by the customer), with a bidirectional BZ version with zero and a maximum frequency of 600 kHz. Output electronics: Line Driver (26LS31 or ET7272), standard NPN, NPN and NPN Open Collector.

The magnetic actuator is mounted on a hollow shaft from Ø4 to Ø10 mm. It withstands shocks of 100 G (6 ms) and vibrations of 10 G (55–2000 Hz). It offers IP67 protection on the shaft side (standard) and IP65 on the output side, depending on the connection. Available in guemisa.es.

  • Technology contactless between the rotating shaft and the transducer body.
  • Until 30000 rpm continuous (+30 % intermittent).
  • Protection IP67 on the axle side (standard) and immunity to oils and liquids.
  • Resolution of 8 to 2048 pulses/rotation with version BZ (bidirectional with zero).
  • max. frequency of 600 kHz with electronics Line Driver and NPN.
