Glossary of Terms
Absolute code
ASIC
Backlash
Binary
Binary code
Bit
Carbon
Cermet
Binary code where only 1-bit changes logic state
from one angular position to the next (a.k.a. Gray
code).
Application-specific integrated circuit
The maximum difference in shaft position that
occurs when the shaft is moved to the same actual
output ratio point from opposite directions.
Two logical states (High, 1, true/Low, 0 false); the
basis of binary data-processing systems.
A specific code utilizing the binary numbering
system (i.e. “0” and “1”).
(incremental encoders) Refers to 1 quantum of
data or 1 increment of digital code. (absolute
encoders) Refers to the number of tracks which
normally equate to 2nth power, i.e., 8 bits = 2
256 discreet positions, likewise 12 bits = 2
4,096 discreet positions.
A mixture of carbon powder and phenolic resin
that is sprayed, screened, or brushed onto a
phenolic or ceramic substrate.
A mixture of metal particles, precious metal
oxides, glass powders, blended with a liquid
vehicle. This material is typically screened onto a
substrate (commonly ceramic) and fired at
temperatures that flow glass to fabricate resistive
elements for potentiometers.

Code
Conductive plastic (CP)
Contact resistance variation (CRV)
Cycles per revolution (CPR)
Cup
Current tap
Electrical cycle
Electrical degree (°e)
The digital output signal produced by an encoder.
A binder or resin blended with carbon powder
and/or other conductive material. This material is
screened onto an insulating substrate to fabricate
resistive elements for potentiometers.
The variation in resistance between the wiper and
a non-wirewound resistive element when the
wiper is energized with a specified current and
moved over the electrical travel in either direction
at a specified speed (does not include the effects of
roll-on or roll-off).
The number of full quadrature cycles per full shaft
revolution (360 mechanical degrees).
A single mechanical section of a potentiometer. A
multi-cup potentiometer may contain one or more
sections, either electrical resistance elements or
switch modules.
An electrical connection fixed to the resistance
element, which is capable of carrying, rated
element current and may distort the output
characteristic.
One complete four-state quadrature cycle. Each
cycle is divided into 360 electrical degrees (°e) and
can be decoded into 1, 2, or 4 counts, referred to as
X1, X2, or X4 resolution multipliers.
1/360 of one full quadrature cycle.
