WWRP - Wirewound Rotary Potentiometers
Product Brand: Penny & Giles
Penny & Giles wirewound rotary potentiometers are legacy products that are custom manufactured to specific order requirements, and are available in three ranges.
Models RP/E are built with end terminals in synchro sizes 08 to 18.
Models RP/S have side terminal configuration and can be built with multi-cup potentiometer systems or where multi-tapping points are required. They are built in synchro sizes 09 to 25.
Models 3410 are end terminal precision potentiometers available in synchro size 15, with resistance values of 1kOhm, 2kOhm or 5kOhm.
These rotary potentiometer designs include a low mass rotor assembly which minimises rotational inertia. Low contact noise and low torque are achieved by using twin noble metal wipers and slip ring brushes. A working life of between 20- to 50-million operations can be achieved, depending on options selected.
Penny & Giles wirewound rotary potentiometers may be operated in the variable resistor mode, in addition to the normal voltage divider mode.
