The 93R1A-R22-A13L 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 selectable resistance values ranging from 100 ohms to 1 megohm. This potentiometer utilizes a cermet element with linear taper characteristics, offering a total resistance tolerance of 5% or 10% and independent linearity of ±5%, ensuring reliable and precise resistance control. The device provides virtually infinite electrical circuit isolation with metal or plastic shaft options and is RoHS compliant. It is commonly used in audio equipment, instrumentation panels, and control systems where accurate variable resistance adjustment and compact panel mounting are required.
