Encoders convert rotation or linear motion into digital — incremental and absolute — feedback for servo and motion. Heidenhain (precision machine tools), SICK (all-round), Baumer (general), Kübler (industrial rotary) and ifm (heavy duty) lead Europe.

FAQ
Q Incremental vs absolute?
A
Incremental: pulses per revolution (1024-65536 ppr), homing required after power-up. Absolute: position known at power-up (multi-turn 25 bit over 4096 revolutions), no homing. Power-fail recovery → absolute.
Q Encoder interface?
A
TTL/HTL (classic incremental); EnDat 2.2, BiSS-C (high-resolution absolute, Heidenhain-patented); SSI (absolute industrial standard); PROFINET/EtherCAT (fieldbus integrated).
Q Linear scale vs rotary encoder?
A
Rotary fits servo shaft ends; linear scales fit machine-tool feed axes + metrology. Heidenhain LS / LB / LIP leads precision machine tools.
