Linear Encoder 300mm

This linear encoder converts movement along it's 300mm of travel into a quadrature signal that is readable by any of our encoder interfaces. It has an index channel that triggers in several places along the length of the encoder to aid in startup calibration.


By default this encoder ships with a DB9 connector that has the following pinout:

DB9 Pinout

Pin 1 2 3 4 5 6 7 8 9
Signal  NC Gnd NC  Shield  NC   A  Vcc B Index
Colour   Black   Shielding   Yellow  Red Green Brown

In order to connect this device to a Phidgets encoder board, you'll need to remove the DB9 connector and solder on the included 5-pin encoder cable.

Comes Packaged with:

Encoder Interfaces

Encoder wiringEncoder wiring

This linear encoder must be read by an encoder interface. These interfaces will interpret the two quadrature signals in order to determine the continuous position of the carriage. If you want to use the device with one of our encoder interfaces you will need to remove the DB9 connector and solder on the included 5-pin encoder cable. You'll need to connect them as follows:

Encoder Green Red Yellow Brown Black
Cable Connector Brown Red White Green Black


The following interfaces are compatible with this encoder:
