The Series 45 Carbon Composition Potentiometer has a proven track record in all aspects of the electronics industry, and can claim to be among the most versatile general purpose potentiometers available.
Our Series 45 potentiometers are highly customisable. Standard pots are fitted with a plastic shaft, but all are available with metal shafts. In May 2017 we re-introduced the knurled and slotted brass shaft model for guitars, a decision driven by customers looking for an alternative to the more commonly used CTS models (here). In addition, to this, the Series 45 is customisable even further by our wide range of resistance values, in linear, logarithmic and reverse logarithmic laws, our shaft options, termination options and bushing options. We can also offer different torque settings on our metal shaft potentiometers from our standard 0.7Ncm to a much higher torque of 3.6Ncm, with varying degrees in between to suit your requirements. This is particularly useful for audio applications where the feel of the pot is critical.
NOTE: When ordering please ensure you choose NONE in the resistance law you do not require. Thank you!
