Measuring Positioning KS17 bsolute Magnetic Encoder - or rotary applications - or linear applications - or 3 track magnetic scales eatures 21 to 24 it absolute resolution 16 it incremental resolution

Motion control with the KS17 accurate - robust - flexible With the KS17 and the corresponding scales OEN offers cost-efficient absolute magnetic measurement solutions for all industrial applications

The KS17 can be used for linear measurements from 330 mm up to 2,350 mm in length and rotary measurements - radial and axial - from 2 mm up to 9,870 mm in diameter.

1 Measuring Positioning KS17 bsolute Magnetic Encoder - or rotary applications - or linear applications - or 3 track magnetic scales eatures 21 to 24 it absolute resolution 16 it incremental resolution Small dimensions for space-saving implementation Resistant to contamination, vibrations, temperature fluctuations, humidity No wear from usage orresponding scales in various diameters and lengths Motion control with the KS17 accurate - robust - flexible With the KS17 and the corresponding scales OEN offers cost-efficient absolute magnetic measurement solutions for all industrial applications where movements have to be measured. The KS17 can be used for linear measurements from 330 mm up to 2,350 mm in length and rotary measurements - radial and axial - from 2 mm up to 9,870 mm in diameter. The encoder provides both ISS- or SSI as output plus incremental signal output in parallel. With a resolution of bits this hollow shaft encoder surpasses typical shaft end applications many times over. With dimensions of 28 mm in length, 16 mm width and a height of 6.6 mm (Molex version) or 3.4 mm ( version) the KS17 is very compact. The protection class IP67 allows the implementation even in harsh environment. OEN Electronic mb Potsdamer Straße erlin ermany on +49 (0) ax +49 (0) magnetics@bogen-electronic.com 1/6
