Quick Start
• Plug the Sensor Plug into a PASPORT input port of
a PASPORT-compatible PASCO interface (such as
the 850 Universal Interface or SPARK SLS).)
• Start the PASCO data acquisition software (such as
PASCO Capstone or SPARKvue). Set up a data dis-
play in the software.
• Click or press ‘START’ to begin recording data.
Turn the shaft of the Rotary Motion Sensor.
Introduction
The PASCO PS-2120A Rotary Motion Sensor is a versatile position and motion measur-
ing device. It measures angles to a resolution of 0.09°, and detects the direction of
motion. Markings on the outside of the case indicate which is the default positive direc-
tion. The optical code wheel inside the sensor has 4000 divisions per revolution (360°),
and the maximum speed is 30 revolutions per second.
The sensor comes with a removable three-step pulley (10 millimeter (mm), 29 mm, and
48 mm diameters), and a rubber “O”-ring that fits into the largest diameter step. The
three-step pulley can be attached to either end of the shaft, and can be placed large-diameter down or large-diam-
eter up on the shaft. A tab on the inside of the pulley matches a notch on the outside of the shaft. The pulley has
a notch and a small hole in the outer edge of the largest and second largest steps for attaching a string. The
included hex key (allen wrench) allows the rod clamp to be removed from the end of the sensor and mounted on
either the right-hand or left-hand side. The hex key fits in the storage hole near one end of the sensor and is held
in place by a rubber “O”-ring inside the sensor..
The end of the sensor where the cord exits the case has a platform for mounting a Super Pulley with Table Clamp
(not included). The T-slot through the sensor is for inserting the optional Linear Motion Accessory rack
(CI-6888). The gear teeth on the rack mesh with the gear teeth on the optical code wheel inside the sensor.
