Eaton M22S-R1K Potenciómetro rotativo, 1 kΩ, 0,5 W, volta única, linear

Precise resistance adjustment in industrial control panels requires a reliable, compact potentiometer that integrates seamlessly with standard 22.5 mm mounting systems. The Eaton M22S-R1K rotary potentiometer delivers a fixed 1 kΩ resistance with linear taper, enabling smooth and predictable signal control for motor speed settings, lighting dimming, or parameter adjustment in automation systems.

Who is it for

Panel builders, machine OEMs, and maintenance technicians who need a durable, panel-mount potentiometer for manual analog input in Eaton M22 series control stations. It suits applications where a single-turn, linear response is required for straightforward operator adjustment.

Main features

• Mono (single element) design with 1 kΩ resistance and ±10% tolerance.
• Linear (Type B) taper for uniform output relative to rotation angle.
• Single turn with 270° electrical rotation and 300° mechanical rotation.
• Rated for 0.5 W power dissipation and up to 100,000 mechanical operations.
• Fits standard 22.5 mm panel cut-outs; connects to Eaton M22 contact blocks via screw terminals.
• Operating temperature range -25 °C to +70 °C, storage -40 °C to +80 °C.
