State Electronics manufactures customer potentiometers for thousands of customers.  These designs are the result of a specific set of mechanical and electrical design parameters.  Once a design has been finalized we assign it a unique part number which is our internal reference to a bill-of-material (BOM).

Typically a part number for any of our customer’s pots will begin with the letter "L" followed by 5-digits.  The first digit would represent the series; 1 = 388/389 series, 2 = 70 series, and 6 = S127 series.  The complete part number represents all of the component parts and assembly instructions for the design and is considered proprietary to State Electronics.

We consider all designs to be proprietary to the original customer and will not under any circumstances, release any information about a design to a 3rd party unless we first receive written permission from the original customer.
If you are the original customer and have a question about a design, please contact our product manager.
