AKP18 Absolute Magnetic Sensing Head
10Pages

AKP18 Absolute Magnetic Sensing Head With the combination of AKP18 and magnetic scales, BOGEN offers cost-efficient solutions for linear and rotational absolute magnetic measurement. The AKP18 is extremely compact and fits even smallest installation space. It is available in nine different standard sizes and enables linear measurements up to 256 mm and rotary solutions, both radial and axial. The AKP18 offers both BISS-C and SSI output options. Thanks to its 18 - 20 bit resolution, this hollow shaft encoder outperforms typical shaft end products. Absolute Measuring Rotary Linear Applications Features and Benefits • 18 to 20 bit absolute resolution • for linear or rotary applications • no wear from use AKP18 rev 4.1 (2021/11/26) • applicable for smallest installation spaces • designed especially for multiple axis robotic and automation applications • accuracy information
