The 93R1A-R22-A05L is a Model 93 single-turn panel control potentiometer manufactured by Bourns, featuring a 5/8" square form factor with multiple pin-out configurations and available metal or plastic shaft options. This device provides virtually infinite electrical circuit isolation and supports a wide range of resistance values from 100 ohms to 1 megohm, with linear or audio taper options depending on configuration. The potentiometer offers independent linearity of ±5%, total resistance tolerance of 5% or 10%, and an absolute minimum resistance of 2 ohms maximum, making it suitable for precision control applications. It is RoHS compliant and commonly used in audio equipment, instrumentation panels, and industrial control systems where reliable, smooth resistance adjustment is required.
