The absolute magnetic sensing head AKS16 for linear and rotary applications: With the AKS16 and the associated scales BOGEN offers inexpensive magnetic linear and rotary absolute measure-ments. The AKS16 provides linear measurements up to 192 mm and rotational solutions both radially and axially, each with six different sizes. The measuring head also provides both BISS-C or SSI as output, plus incremental signal output in parallel. With a resolution of 18-20 bits this hollow shaft sensor surpasses typical shaft end applica-tions many times over. With dimensions of 24.2 mm in length, 16 mm width at a height of 6.6 mm (Molex version) or 3.4 mm (FFC version), the measuring head is extremely compact.

CalibrationEach unit needs to be calibrated in final assembly with a nonius scale. 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 losser performance or operation of the encoder!
