The attraction of magnetic encoders
Encoders that measure absolute position magnetically rather than optically come from Turck, Minneapolis.
The Kubler 3650 and 3670
encoder Series give a resolution of 9 bits with SSI, 4-to-20 mA, or
0-to-10-Vdc output. The encoders have an IP69K protection rating
and temperature range of –40 to 85˚C so they can work outdoors.
Their die-cast housings are said to resist shock (>500 g) and vibration (>30 g).
A compact design and blind
hollow shaft of up to 10-mm
diameter lets the encoders
mount in tight spaces and on
a tight radius, even with large
shafts. Additionally, the magnets can be configured for a
suitable measuring range (45˚,
90˚, 180˚ or 360˚) as needed. Integrated LEDs for reference
point detection simplify startup and fault diagnostics during
maintenance.
