EACEAC50 / EAC58 Absolute Singleturn Encoders (EAC58A, EAC58P, EAC58-DP, EAC58-EAND)
Absolute Singleturn Encoders ELCO EAC

Absolute singleturn encoders output a unique code for every shaft position within one revolution and need no reference run after power loss. The core range is EAC58 (Ø 58 mm): shaft (EAC58A) and hollow-shaft (EAC58P) versions with SSI or parallel Gray/binary output up to 13 bits (8192 steps), EAC58-DP with Profibus-DP (12 Mbaud, terminal box with DIP-switch addressing) and EAC58-EAND with 4–20 mA current output over 0–360°. The compact EAC50 (Ø 50 mm) offers NPN/PNP parallel output up to 10 bits.
