AKS16 Absolute Magnetic Sensing Head
11Pages

AKS16 Absolute Magnetic Sensing Head AKS16 can be used for linear measurements up to 256 mm in length and rotary measurements - radial and axial - up to 79 mm in diameter. The encoder provides both BISS-C or SSI as output plus incremental signal output in parallel. With a resolution of 18-20 bits this hollow shaft encoder surpasses typical shaft end applications many times over. With dimensions of 24.2 mm or 28 mm in length, 16 mm width and a height of 6.6 mm (Molex version) or 3.4 mm (FFC version) the AKS16 is very compact. Absolute Measuring Rotary Linear Applications Features and Benefits • 18 to 20 Bit absolute resolution • 18 Bit incremental resolution AKS16 Rev 2.6 (2020/08/31) • Small dimensions for space-saving implementation • Resistant against contamination, vibrations, temperature, fIuctuations, humidity • No wear from usage • Corresponding scales in various diameters and lengths

Features absolute resolution * commutation signal for 1 to 16 pole pairs (UVW) resolution 18 Bit: up to 24,000 rpm rotation speed resolution 19 Bit: up to 12,000 rpm resolution 20 Bit: up to 6,000 rpm pole pitch sensing head optimal distance:magnetic target supply voltage maximum output load energy consumption (without load) operating temperature storage temperature protection class 4 and 262144 in steps of four based on pole pitch pole pitch maximum torsional moment of threaded inserts * resolution depends on the diameter/length of the scale Output Signals ABZ signals / inverted signals...

For the calibration, the scale needs to be moved over the whole measuring length. For calibration, the programming unit including cables and the BOGEN software will be needed. A PC is required for the calibration. The use of non BOGEN approved software may result in lesser performance or...
