Haydon Kerk Motion Solutions Inc. has introduced an integrated magnetic encoder option to its 1-inch 25000 Series linear actuators. The enclosed incremental encoder utilizes solid state technology and includes both analog detection circuitry and full signal processing from a single chip.

The 64 line quadrature encoder system utilizes a high energy neodymium magnet and provides an 8 bit digital resolution resulting in a total of 256 output pulses per revolution. The encoder provides 90 degree phase shifted A/B output channels along with a single index pulse for every complete shaft rotation. The encoder circuitry samples angular position at 10,000 samples per second for an output update every 100 microseconds.

The Haydon 25000 Series is part of the G4 line of high-output can stack linear actuators and are “second to none” in performance when compared to similar sized actuators in the marketplace today. Improvements include optimized stator tooth geometry, high energy neodymium magnets, custom engineered polymers, and larger ball bearings for greater rotor support and axial loading.
