Tolerance on Rated Resistance: ± 20% Optional Tolerance on 1K - 1M: ± 10% Resistance Laws (Taper): Linear: A Non linear: B (Audio/Log) or C (Reverse Audio/Anti Log) Other laws: Please refer to Sales office Resistance law A (Linear) curve
Resistance law B (Audio/Log) curve
Resistance law C (Reverse Audio/Anti Log) curve Linearity As a basis of assessing Linearity Tolerance the independent method is the most practical, permitting as it does, the reference curve to be aligned as near as possible to the actual output curve. This avoids the use of the theoretical starting and finishing points, it is normal for the customer to realign the achieved curve with series trimmers at each end of the device if required.
Linearity Tolerance is 4% over the Nominal Resistance range of 1K0 to 1M0. The Linearity Tolerance is measured on at least 70% of the effective rotation range. Note. In the case of Terminal and Zero-based linearity, both present constraints which increase the manufacturing difficulty and in consequence have an adverse effect on the product's price and availability.

6.0mm Diameter Spindles Note: *Specials to customer's specification up to 65mm.
4.0mm Diameter Spindles Note: The orientation of the flat as illustrated is for plastic spindles only. For metal spindles, unless specified on the order, the orientation may be different on each potentiometer type. 6.35mm Diameter Spindles Note: *Specials to customer's specification up to 65mm.
Splined Spindle - 6.0mm dia. 18 teeth A splined form is available on the 6.0mm diameter P16 plastic spindle (F5) or alternatively, a 6mm 'Splined Adaptor' (8.7mm long) can be fitted on a 4mm dia.
OMEG POTENTIOMETER CODING The model type given to our potentiometers is explained on this page and covers both unswitched and switch potentiometers. Please note that not all options are available in each potentiometer range. A unique code, or part number that specifies all the parameters of the potentiometer down to the specific spindle, is not used due to the bespoke nature of our business, please return to your previous page where you will find links to an enquiry form for your use.
SWITCH CODE The switch code is dependent on the switch body that is fitted and will be preceded with a slash (/).
