Glossary of Terms
Resolution (encoder)
Resolution (potentiometer)
Rheostat
Roll-on/Roll-off
Rotational life
Running torque
Shaft
Shaft endplay
The number of full quadrature cycles per full shaft
revolution (360 mechanical degrees). Each cycle
can provide 1, 2, or 4 counts (i.e., X1, X2, and X4
decoding or multiplication) depending on how the
signal is decoded. Resolution is normally stated in
pulses per revolution (PPR).
A measure of the sensitivity to which the output
ratio of the potentiometer may be set.
A variable resistor configured so that all the
current flows through the wiper.
The abrupt output voltage or resistance change
observed as the shaft is displaced from the end of
mechanical travel into the electrical travel.
The ability of a component to withstand a
specified number of cycles under specific operating
conditions while remaining within allowable
specifications.
The rotational force required to sustain uniform
shaft rotation at a specified speed in the clockwise
or counterclockwise directions throughout the
mechanical travel.
The mechanical input interface of the
potentiometer.
The total axial excursion of the shaft, measured at
the end of the shaft with a specified axial load
supplied alternately in opposite directions. Shaft
endplay is expressed in inches.
Shaft radial play
Shaft revolution
Shaft runout
Solderability
Starting torque
State
Stop strength
The total radial excursion of the shaft, measured
at a specified distance from the front surface of the
component. A specified radial load is applied
alternately in opposite directions at a specified
point. Shaft radial play is expressed in inches.
One complete 360° turn of the shaft of a rotary
encoder in a single direction.
The eccentricity of the shaft diameter with respect
to the rotational axis of the shaft, measured at a
specified distance from the end of the shaft. The
body of the potentiometer is held fixed and the
shaft is rotated with a specified load applied radial
to the shaft. The eccentricity is expressed in inches,
TIR.
The adhesion of molten solder to the terminals of
a component, producing a continuous coat of
solder without voids and pinholes under specified
conditions.
The rotational force required to initiate shaft
rotation of a rotary component in the clockwise or
counterclockwise directions anywhere in the
mechanical travel.
The logic levels generated in the output signal of a
digital component (High, 1, true/Low, 0 false).
The maximum load that can be applied to the
shaft at each mechanical stop for a specified period
of time without permanent change of the stop
positions greater than specified.
