Ø58mm absolute encoder
Photoelectric absolute singleturn and multiturn rotary encoder series AK58 is constituted of 6 different models – AK58M, AK58B, AK58C, AK58C2, AK58C3 and AK58D. Encoders use SSI, BiSS serial interfaces and output up to 21 bit singleturn and 24 bit multiturn resolutions through binary or Gray codes.
