Piher Potentiometer Pt15 10k 470k Carbon Film Variable Resistor
Piher Potentiometer Pt15 10k 470k Carbon Film Variable Resistor
Description
The PT15 carbon film potentiometer is a compact and high-performance solution for applications requiring reliable and frequent manual adjustments. With a 15mm diameter and shaftless design, it supports a wide range of interface mechanisms—from customized knobs to motorized adjustments.
Engineered with a carbon or cermet resistive element, this potentiometer ensures accurate control with linearity up to 3%, supporting resistance values from 100Ω to 5MΩ. It features tactile detents (up to 38), long operational life (up to 100,000 cycles), and IP54-rated protection for use in demanding environments.
