Combined Precision Potentiometer & Multi-function Switch.
The PL320 potentiometer from Variohm is an enhancement
of the existing Contelec PL300/310 Range.
In addition to being designed to offer high accuracy under extreme
environmental conditions it can also offer the user customised signal
The ability to integrate switches in this manner opens up many new
fields of application perhaps the most obvious one being joystick
controllers. The PL320 is normally supplied with continuous mechanical
rotation and with an electrical function angle of between 15 and 348
degrees. The ability to have a second, redundant, output signal is
optional as is the possibility of incorporating one or more switches
into the 22 mm diameter housing.
The PL320 comes with a standard linearity of +/- 1% but this can
be improved up to 0.25% if the application demands it. Despite its
high accuracy the PL320 will operate safely and reliably even in the
most arduous conditions. It has an lP65 sealed housing, can operate
over a temperature range of -25°C to +85°C and can tolerate vibration
and shock of 10g and 50g respectively, whilst offering a life expectancy
of better than 5 Million cycles.
The PL320 is so flexible that even the mode of connection can be
customised. The user has a choice of round or flatband cable
encapsulated into the housing or he can specify solder pins, a
multipole connector or even AMP terminals.
