Beckman Industrial A-R5K-L.05 Helipot Precision Potentiometer

Beckman Industrial A-R5K-L.05 Helipot Precision Potentiometer is a legacy Beckman Helipot dial-type resistor designed for precise, repeatable resistance adjustments in instrumentation and control panels, with the A-R5K-L.05 designation placing it in Beckman’s 5K-series Helipot family for pilot-device applications. The Helipot line was developed by Beckman Instruments (originally National Technical Laboratories) to provide robust, high-precision resistance changes through a helical coil design, a hallmark of the Helipot division. Historically, Helipots have been used in a variety of precision contexts including pH meters, aircraft control systems, analog computers, and medical monitoring devices, illustrating their role as fine-control components in both laboratory and industrial equipment. As a member of the 5K-ohm class, this model is aligned with other Helipot variants intended for exacting control in instrument panels and pilot-control assemblies.
