SR-PT65 9,5/4,4 – HARTMANN

The HARTMANN SR-PT65 9,5/4,4 is a rotary control knob designed for panel-mounted potentiometers or rotary encoders with a 6.35 mm (1/4 inch) diameter shaft. Constructed from a durable, unspecified blue polymer, this segment wheel knob features a segmented outer rim to facilitate tactile grip and precise incremental adjustments. The “9,5/4,4” designation likely refers to key dimensional specifications, with “9,5” indicating the approximate outer diameter of the knob in millimeters and “4,4” potentially representing the inner bore depth or collar height, also in millimeters. The knob is secured to the shaft via a set screw mechanism, allowing for secure and repeatable positioning. Its operational temperature range and torque specifications are not explicitly defined but are typical for similar control knobs intended for general electronic equipment applications.
