Rotary Potentiometers


series potentiometers CW-18 are manufactured in a sealed metal housing, with a cermet resistive element, which is much more durable than typical carbon tracks. The element has a linear characteristic (A). Potentiometers are available in a hermetic housing (marked "H") and with resistance tolerances of 5% and 10%.
