Photoelectric absolute singleturn and multiturn rotary encoder series AK58 is constituted of 7 different models – AK58M, AK58B, AK58C, AK58C2, AK58C3, AK58D and AK58 EtherCAT. Encoders use SSI, BiSS or EtherCAT serial interfaces and output up to 24 bit singleturn and 40 bit multiturn resolutions through binary or Gray codes.
