Haydon Kerk Motion Solutions Inc., a leading manufacturer of
precision linear motion products, offers an integrated magnetic encoder
available on the 1 in. 25000 Series linear actuators.
The extremely compact and fully enclosed incremental encoder
utilizes solid state technology and includes both analog detection circuitry
and full signal processing from a single chip. When combined with the Haydon
can stack linear actuator, excellent position feedback can be obtained for use
in critical applications including medical equipment, analysis devices, and
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 256 pulse magnetic encoder is a great replacement for
optical encoders and is virtually immune to vibration, shock, dust, and
contaminants. The encoder can be operated using either a 3.3 or 5 V input
voltage. When combined with the Haydon 25000 series linear actuator, a robust,
compact linear motion package is created.
