The PhidgetEncoder Highspeed 4-Input can be used with a wide assortment
of mechanical and optical encoders. The encoder should be of quadrature
output type, indicating that there will be two quadrature output channels
(usually labeled A and B) and an optional third output channel to
signal when the index pin (a reference point for zero position or
a complete revolution) has been reached.
The PhidgetEncoder Highspeed 4-Input is able to read four encoders
simultaneously. Encoders are not powered up until all initialization
of the device is complete. It is possible to enable some or all encoders,
depending on how many of the channels are being used. This can also
be used to reduce power consumption when certain encoders are not
The PhidgetEncoder Highspeed 4-Input has the added ability
to time the duration between a group of quadrature changes. The time
is returned in microseconds. This time value can be used to calculate
velocity and acceleration.
Both mechanical and optical encoders are available, with optical encoders
dominating at > 100 counts per second. Review the data sheet for
the encoder you are planning to use to ensure it is compatible with
the PhidgetEncoder Highspeed 4-Input. Almost any incremental quadrature
encoder will work but it is important to verify this before connecting
it to the Phidget. Absolute encoders will not work with this device.
Ideally, you should choose a quadrature encoder with a 5-pin output
and the following pinout in order to be directly compatible with the
This particular revision of the 1047 has improved power switches to
enhance system stability when turning off and on separate encoder
inputs. It also has updated firmware with a few minor bug fixes.
