Compact String Pot
SP1
The Celesco SP1 String Pot is a compact, economical
and durable device that utilizes a flexible cable, a spring-loaded spool, and a potentiometer to detect and measure linear position.
The SP1 is designed for tight spaces, high-cycle applications
and generously allows cable misalignment. With 4 different measurement ranges and handy mounting brackets, the SP1 is a perfect solution for many applications, from light industrial to OEM.
