AMCI ME15 Absolute Analog Rotary Shaft
Encoder |
AMCI's ME15 Analog encoder utilizes a small diametrically polarized
magnet and a custom ASIC that contains an array of Hall sensors
that generate a voltage when exposed to a magnetic field.
The ASIC detects the change in magnetic flux distribution
as the magnet rotates above it and outputs a voltage level
that represents the angular position. The ASIC also has the
ability to ignore any interfering magnetic fields, allowing
the ME15 to operate in areas of high external fields.

The Analog output version of the ME15 can be ordered
to output its minimum to maximum output over the four
Angular Ranges listed above. However, the next minimum
to maximum cycle always begins at the start of the next
full turn.
The following diagrams show the output waveforms for
the four angular ranges of an encoder ordered with CW
increasing output.
