Incremental encoders

Encoder for speed and position measurement in extreme ambient conditions

Heavy industry places tough demands on the reliability and lifetime of the components utilized. That applies in particular to incremental encoders installed to measure and monitor speeds.

No matter if they are installed on drives in steel and rolling mills, in mining operations, in crane systems or in the oil and gas industry, each field of application has its own specifications: from diff erent mounting solutions and extension options to diff erent pulse rates, supplementary signal outputs, integrated FOC transmitters through to stainless steel housings or special certifi cations such as SIL / PL for functional safety and ATEX / IECEx for potentially explosive atmospheres.

The challenge is to provide a tailor-made solution for each task and every mounting situation – and to guarantee the reliability of each and every solution.

Product overview

  • Incremental encoders FG 40 / FGH(J) 40

    Incremental encoders FG 40 / FGH(J) 40

    The incremental rotary encoders FG 40 (solid shaft) / FGH (J) 40 (hollow shaft) can be deployed in a wide variety of applications to measure the speed of standard, auxiliary and secondary drives in heavy industries such as steel and rolling mills, in mining operations as well as in ports and crane systems.

  • Incremental encoders FGH 6

    Incremental encoders FGH 6

    The incremental optical rotary encoders FGH 6 for continuous hollow shafts up to Ø 50 mm are mostly mounted on the unused shaft end by means of an isolated adapter flange or directly onto the shaft.

  • Incremental encoders FGH 8

    Incremental encoders FGH 8

    The incremental optical rotary encoders encoders FGH 8 for continuous hollow shafts up to Ø 80 mm are mostly mounted on the unused shaft end by means of an isolated adapter flange or directly onto the shaft.

  • Incremental encoders FGH 14

    Incremental encoders FGH 14

    The incremental optical rotary encoders FGH 14 for continuous hollow shafts up to Ø 150 mm are mostly mounted directly onto the shaft. Thanks to the flat design the optical rotary encoders are ideally suitable for attaching further sensors such as speed switches, absolute encoders or combinations of these.

  • Incremental encoders FG 41 SIL 3 / FGH 41 SIL 3

     Incremental encoders FG 41 SIL 3 / FGH 41 SIL 3

    The extremely rugged incremental optical encoders FG 41 (solid shaft) / FGH 41 (hollow shaft) are specifically designed for safety applications in heavy industry.

  • Incremental encoders FGHJ 5

    Incremental encoders FGHJ 5

    The incremental hollow shaft encoders FGHJ 5 with insulation are ideally suitable for use on inverter-controlled drives where shaft currents are a concern.

  • Incremental encoders FG 2 / FGHJ 2

    Incremental encoders FG 2 / FGHJ 2

    The incremental optical encoders FG 2 (solid shaft) and FGHJ 2 (hollow shaf) ensure the speed of standard, auxiliary and secondary drives is reliably measured.

  • Incremental encoders FG INOX / FGHJ INOX

     Incremental encoders FG INOX / FGHJ INOX

    The incremental rotary encoders FG(HJ) INOX are acid-, alkali- and saltwater-resistant encoders. Their stainless steel housing ensures they function long-term perfectly under the influence of aggressive media in heavy-industry environments.

  • Incremental encoders FG 40 Ex

     Incremental encoders FG 40 Ex

    The incremental optical encoders FG 40 Ex (solid shaft) can be deployed in a wide variety of applications to measure the speed at standard, main and secondary drives in potentially explosive atmospheres, for example in the oil and gas industry as well as in petrochemical applications.

  • Protective cover for incremental encoders

    Protective cover for incremental encoders

    Occupational safety is important, which is why we have introduced a new addition to our well-established FGH 6 encoder system solution: a made-to-measure protective cover that reliably prevents accidents caused by rotating parts.
