Assembly
The 3-step pulley can be mounted on the rotating shaft in either of two
orientations: with the wide side of the pulley near the sensor body, or with the
narrow side of the pulley near the sensor body. The easiest way to insert the
3-step pulley on the Rotary Motion Sensor shaft is hold the shaft to prevent
rotation as you turn the pulley to align the key to the slot. The O-ring can be
slipped over the outer pulley to increase friction when the pulley is in contact
with a surface.
The thumb screw can be threaded into the back of the sensor allowing the
Rotary Motion Sensor to be attached to a ring stand.

The sensor also has a set of accessory mounting holes that allow it to connect to
existing accessories such as the Polarizer Analyzer (PAK-OEK) and the Rotary
Motion Motor Kit (MK-RMV).
