Glossary of Terms
Lateral runout
Load
Mechanical angle
Minimum resistance
Noise
Non-wirewound
Output ratio
Output smoothness
The perpendicularity of the mounting surface with
respect to the rotational axis of the shaft measured
on the mounting surface at a specified distance
from the outside edge of the mounting surface. The
shaft is held fixed and the body of the
potentiometer is rotated with specified loads
applied radial and axial to the body of the pot.
The lateral runout is expressed in inches, TIR.
The ability of a component to dissipate rated
power for a specified length of time under specific
operating conditions while remaining within
allowable specifications.
The total travel of the shaft between integral stops;
in potentiometers without stops, the mechanical
travel is continuous.
The resistance measured between the wiper
terminal and any other terminal with the shaft
positioned to give the minimum value.
Any spurious variation in the electrical output not
present in the input.
A resistive element made by screening a film of
conductive plastic, cermet or carbon inks on a
substrate, which may be fabricated from ceramic,
phenolic or other type of insulator material.
The ratio of the output voltage to the designated
input reference voltage. Unless otherwise specified,
the reference voltage is the total applied voltage.
A measurement of any instantaneous variation in
the electrical output not present in the input.
Output voltage
Potentiometer
Phase
Phase reference point
Pilot diameter runout
Power rating
PPR Pulses per Revolution
Quadrature
The voltage between the wiper and the designated
reference point. Unless otherwise specified, the
designated reference point is the CCW terminal.
A variable resistive device used in applications,
which typically require frequent or even constant
adjustment.
The relationship between channel A and channel
B; the rising edge on channel A to rising edge on
channel B measured in electrical degrees (°e).
The reference point on a potentiometer cup,
usually an output ratio or an intermediate tap.
The reference point is used to align the cups in a
multi-cup potentiometer.
The eccentricity of the pilot diameter with respect
to the rotational axis of the shaft, measured on the
pilot diameter. The shaft is held fixed and the
body of the potentiometer is rotated with a
specified load applied radial to the body of the pot.
The eccentricity is expressed in inches, TIR.
The maximum power that a component can
dissipate under specified conditions while meeting
specified performance requirements.
(see Resolution)
The square wave output code generated by an
incremental encoder. Normally, two output
channels out of phase by 90°e.
