Haydon Kerk Motion Solutions Inc. (www.haydonkerk.com) has introduced a new magnetic encoder that utilizes both full signal processing and analog detection circuitry on single chip. It is available on the one-inch Series 25000 linear actuator.
Fully enclosed and extremely compact, the incremental encoder includes both full signal processing and analog detection circuitry from a single chip while using solid state technology. For excellent position feedback in critical applications such as analysis devices, medical equipment and robotics, the 64-line incremental magnetic encoder must be used together with the Haydon can stack linear actuator.
The quadrature encoder system uses a high energy neodymium magnet and offers an eight bit digital resolution that results to a total output of 256 pulses per revolution. For every complete shaft rotation, the encoder delivers a 90 degree phase shifted A/B output channels together with one index pulse. At an angular position, the encoder circuitry delivers 10,000 samples per second.
The 256 pulse incremental magnetic encoder is virtually immune to shock, vibration, contaminants and dust. It is also a great alternative for optical encoders. It can be operated using either a 5V or 3.3V input voltage. It produces a compact, robust linear motion package when combines with Haydon 25000 series linear actuator.
The Haydon 25000 Series’ performance is “second to none” compared to actuators of the same size. Improvements include custom engineered polymers, high energy neodymium magnets, optimized stator tooth geometry, and larger ball bearings for better rotor support and axial loading.
