Profile: Samarius Precision Instruments, Inc. is a provider of potentiometers. Our sub-miniature precision potentiometers are ideal components for weight reduction and miniaturization requirements in aircraft, guided missile & portable equipment. Our rotary potentiometers are completely enclosed by molded covers with integrally cored, solid terminals that cannot loosen or transmit solder and resin. Our 2"diameter rotary potentiometers includes sleeve bearing C-200 and ball bearing BC-200 rotary potentiometers. Our ball bearing rotary potentiometers model includes feature such as lower starting and running torque, improved linearity because of reduced radial shaft play, minimized backlash between ganged rotary potentiometer sections for accurate function repetition or solution of mathematical equations.
