Simple potentiometer
£4.20 – £7.80 inc VAT
We stock two basic 10k pots; a standard 300°, and our own 50° version.
Description
We have two versions of a simple potentiometer, a standard 10K linear pot with a 300′ arc, and a custom made 50° version. Both are rated at 1/4 W. These pots are plastic bodied with a plastic shaft so they have good water resistance. They are IP50 rated by the manufacturer (Omeg Ltd), and have a lifetime rating of >20 000 operations.
We consider these pots to be a bit like car brake pads, they have a spring-loaded metal arm which presses on a soft carbon track and these will wear out over time. A lot of intermittent control problems are solved by replacing the pot. Note: As of 4th May 2023 the design of the 50° version has been improved to make it longer lasting.
Standard potentiometer
A standard 10K linear pot (10K ±20%) to suit all our controllers (except Porter 40). The shaft rotates through 300°. It has the same dimensions as the 50° pot below, but with solder tags rather than PCB pins.
Special 50° potentiometer
This is a pot made specially for 4QD: it is a ‘standard’ 10K (10K ±20%) linear pot (i.e. with 300° mechanical travel) but with the active resistive part of the track occupying only the centre 50° of the mechanical travel. Note: As of 4th May 2023 the design of the 50° version has been improved to make it longer lasting. See this article for more details.
These are the pots used in our hand control box [RBT] and bell throttles. A lever to fit it is available separately.
