Long-term stable sealing concept

Long-term stable sealing concept

  • The elaborate Baumer HeavyDuty sealing concept allows the protection class IP 66 and IP 67 over a wide temperature range up to +95 °C.
  • Thanks to a sophisticated combination of labyrinth and shaft seals, the HeavyDuty encoders are permanently protected against all types of solid, moist and pasty contamination.
 Reliable protection against shaft currents

Reliable protection against shaft currents

  • Particularly in the case of rotary encoders on frequency converter-controlled electric motors, current overshoots in the ball bearing of the rotary encoder may occur.
  • The lubricant can burn locally and the lubricant effect can be impaired.
  • Electrically insulated bearings provide a remedy for this failure.
  • Some hollow shaft designs come with isolated or hybrid ball bearings to compensate shaft currents.
  • Additional slip ring earthing  (optional) can be used for capacitive shaft current discharge.
  • Solid shaft encoder designs provide spring washer couplings with isolated hub as protection against shaft currents.

Integrated function monitoring

Integrated function monitoring

  • The integrated function monitoring EMS (Enhanced Monitoring System, Option) continuously checks numerous rotary encoder functions.
  • The convenient diagnostics enables higher availability, because connection and encoder errors are detected more quickly.
  • The encoder status can be continuously transmitted to the controller via an error output.
Leading edge SinCos signal quality

Leading edge SinCos signal quality

  • LowHarmonics is the world's leading technology for producing sinusoidal signals with a negligibly small harmonic content.
  • LowHarmonics sine wave encoders provide better control, lower drive heating and higher energy efficiency.
Mechanical and electronic speed switches

Mechanical and electronic speed switches

  • Mechanical and electronic speed switches often fulfill the decisive safety function when overshooting or subtracting rotary speeds, in addition to the rotary encoder.
  • In applications with functional safety, our speed switches are classified as standard components as defined in the Machinery Directive 2006/42 / EC.
  • The assessment and certification of the complete system with speed switches according to e.g. EN ISO 134849 is mandatory to be carried out by a notified body.
