Incremental optical encoders, safety certified (SIL 3, PL e)

The incremental optical encoders FG 41 (solid shaft) / FGH 41 (hollow shaft) are extremely robust and specially designed for safety applications in heavy industry, for example in the wet area of ​​rolling mills. The SIL-certified encoders offer a high level of safety up to SIL 2 / PL d (position-oriented) and SIL 3 / PL e (speed-oriented).

Reliable

The incremental optical encoders of the FG(H) 41 series work reliably even under extreme conditions and ensure high system availability. This avoids failures and downtimes.

  • Saltwater-proof, wet areas in rolling mills
  • Large bearings with high dynamic load rating
  • Shaft made of non-corroding steel
  • High shock and vibration resistance
  • Temperature range -40 °C up to +85 C°

Safe

Embedded in an extremely robust, thick-walled housing made of seawater-proof aluminium, the modern electronics of the incremental optical encoders are characterized by electromagnetic compatibility (EMC).

  • Up to 4096 pulses HTL / TTL
  • Up to 4096 sine periods
  • EMC cable glands
  • Safety certified up to SIL 3 / PL e

Tailor-made and comfortable

Thanks to a wide variety of device and signal options the incremental optical encoders of the FG(H) 41 series can be optimally adapted to the respective area of ​​application. They can easily be integrated into existing mounting situations and plc systems.

Engineering support and a wide range of mechanical accessories ensure safe and precise assembly, even in difficult mounting locations.

  • Generously dimensioned terminal box
  • Connection options with a variety of connectors or cables
  • Suitable mechanical accessories and mounting service (optional)
