Attractively priced quality potentiometers.
Most potentiometers offer you a simple choice an
attractive price or a decent specification.
The model PC2O from Variohm Components bridges
the gap between these two extremes.
The PC20 is available as a with a Cermet element for hand adjustment
or with a Conductive Plastic element for use in positional feedback
systems. In either case the rugged design makes the PC20 suitable
for use in even the very worst of conditions. The fully sealed housing
ensures that a reliable, good quality signal will be achieved even under
conditions of extreme vibration. The PC20 will tolerate 20 g vibration
over the frequency range 30-2000 Hz (this assumes a maximum
movement of 0.75 mm)
Nominal resistance values are 1 k.ohm to 1 M.ohm depending upon
the elemnt material. It can have an electrical function angle of between
50 and 320 degrees and a linearity of better than 5% which is
outstanding for this class of potentiometer. The plastic housing
measures 16 mm high, 20 mm wide and 20 mm deep, electrical
connections are made via integral cables or solder pins.
The life expectancy is a remarkable 2 million operations for the
Conductive Plastic version and 50,000 cycles for the Cermet.
The PC20 is designed as standard to offer maximum value, it is
however available with a whole host of customer specified options.
These include different shaft materials such as plastic, brass or
stainless steel. The standard shaft is 6mm diameter with a 5mm
flat on it but other designs can be accommodated. For really high
vibration applications a special high torque option is available
in order to prevent accidental operation.
