The 3310C-111-102L is a 9 mm square sealed panel control potentiometer manufactured by Bourns, designed for professional audio and industrial control applications. It features a conductive plastic element with a 100 kO resistance value (code 102), in-line straight terminals with 2.54 mm center spacing, a flatted shaft end, and a 6.35 mm × 6.35 mm plastic bushing for secure panel mounting. The potentiometer delivers a mechanical angle of 300° nominal with a maximum starting torque of 3.53 N-cm (5.0 oz-in.) and running torque of 4.5 N-cm (4.0 lb-in.) for plastic bushing versions, ensuring smooth and reliable operation. It meets IP67 sealing rating, withstands typical industrial washing processes, and is RoHS compliant, making it ideal for sealed control panels in audio equipment, industrial machinery, and professional audio systems where durability and environmental resistance are essential.
