Description
Vishay Sfernice Precision Marine Potentiometer
Model: 176SF1B202W193 | 2KΩ (2K Ohm) Impedance | Genuine Maritime Grade Control Spare
Condition
Used / Machine Pull — Sold As-Is
— This authentic Vishay Sfernice precision sensor was salvaged from a dismantled industrial/marine control layout. It has been externally cleaned and visually checked, but has not been properly bench-tested for total resistance sweeps, tracking noise, or full linearity specs. The item is being offered in “As-Is” condition. Please review the attached original listing photographs closely to verify the exact structural condition, terminal pins, and mounting bushing details prior to purchase.
Product Overview
