Transducer, Cable Extension
Handy Mounting Bracket
Mounts easily and quickly in several directions
Designed for Cable Misalignment
Long cable life, even when installation isn’t perfect
Polycarbonate Enclosure
Withstands impacts and chemicals
“Free-Release” Tolerant
Greatly reduces damage due to mis-handling of cable
The SP1 String Pot is a compact, economical and durable device that utilizes a exible
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
