AKS17 Absolute Magnetic Sensing Head With the AKS17 and associated scales, BOGEN offers cost-efficient absolute magnetic measuring solutions for all industrial applications where movements have to be measured. AKS17 can be used for linear measurements from 330 mm up to 2,350 mm in length and for rotary measurements - radial and axial - from 102 mm up to 9,870 mm in diameter. The sensing head offers BISS-C or SSI as output as well as a parallel incremental signal output. With a resolution of 21 - 24 bits, this hollow shaft encoder outperforms typical shaft end applications many times over. With dimensions of 28 mm length, 16 mm width and a height of 6.6 mm (Molex version) or 3.4 mm (FFC version), the AKS17 is very compact. IP67 protection class enables use even in harsh environments. Absolute Measuring Rotary Linear Applications Features and Benefits • 21 to 24 Bit absolute resolution • 18 Bit incremental resolution • Small dimensions for space-saving implementation AKS17 rev 3.0 (2021/08/23) • Resistant against contamination, vibrations, temperature, fIuctuations, humidity • No wear from usage • Corresponding scales in various diameters and lengths
