Rotary Sensor Offers Alternative to Encoder Technology

The PST-360 rotary, through-hole position sensor combines a through-shaft design with 360º absolute position feedback in an extremely thin package. It incorporates a proprietary ring magnet with a fully sealed Hall ASIC as the sensor element. This combination is truly non-contacting and does not rely on gears or other interfacing parts and therefore matches the durability specifications of the final application. Measuring 9.8-mm thick with a body diameter of 37 mm and a 50-mm mounting-hole spacing, engineers can now integrate a fully featured rotary sensor directly on existing shafts without the packaging issues that typically accompany encoders or other through shaft sensing devices.  The standard model features a rotor with a 14.05-mm inside diameter (double flatted) shaft design.  Other custom rotor configurations are available.
