EAMEMM36 / EAM58 / EAM90 Absolute Multiturn Encoders
Absolute Multiturn Encoders ELCO EAM

Absolute multiturn encoders store both angle and revolution count, so no reference run is needed after power loss. The main EAM58 series (Ø 58 mm, Ø 6–10 mm shaft or Ø 8–15 mm hollow shaft) is available with SSI, 4–20 mA, Profibus-DP, PROFINET, EtherNet/IP, EtherCAT and CANopen interfaces; typical resolution is 8192 steps × 4096 revolutions, and the -PNOM, -ENOM and -ECOM versions use magnetic sensing. The compact EMM36 (Ø 36 mm) offers SSI or CANopen, and the EAM90 with through hollow shaft up to Ø 28 mm offers SSI or Profibus-DP. IP65, −40…+80 °C (EAM90 −20…+80 °C).
