The 91C2D-D24-E15/E15L is a 5/8" square single-turn panel control potentiometer manufactured by Bourns, featuring Model 93 PC pin terminals in an "L" pattern configuration. This potentiometer is available with multiple resistance tapers including linear (A, B, E, H) and audio (C, D, F, G, S, T) options, with standard resistance ranges from 1 kO to 1 MO for conductive plastic elements and 100 O to 1 MO for cermet elements. The device offers virtually infinite electrical circuit isolation with metal or plastic shaft options, and is available in RoHS compliant versions. The mounting surface features a 22.86 ± 0.43 mm (0.900 ± 0.017") width with PC pin terminals spaced 12.70 ± 0.229 mm (0.500 ± 0.009") apart. This potentiometer is ideal for audio equipment, instrumentation panels, and control applications requiring reliable, compact panel-mounted variable resistance elements.
