Novotechnik U.S., Inc: Touchless rotary position sensor
The Vert-X 22 Series of touchless sensors from Novotechnik feature a permanent magnet that is secured to the rotating object so that there is no direct mechanical linkage between the shaft and the measuring system, resulting in no wear.
Vert-X 22 Series sensors are absolute sensors so they retain their
values even after power interruptions. They feature compact designs of
less than 1 inch in diameter, sealing to IP68 and the measurement angle
is factory programmable. Key specifications for Vert-X 22 include: 0
to 360° measurement range; resolution to 14-bit; repeatability of 0.1°
or better; and maximum hysteresis of 0.1°. Eight output options are
available. Redundant output versions are offered as well.
