The SP2 String Pot from Celesco is a compact,
economical and water resistant device that
utilizes a flexible cable, a spring-loaded spool
and a potentiometer to detect and measure
linear position.
The SP2 is identical to the SP1 except for an
added 40-inch electrical cable with a watertight
rubber strain relief. The SP2 has been
compactly designed for tight spaces and high
cycle applications and generously allows for
measuring cable misalignment. With 4 different
ranges and a handy mounting bracket, the SP2
is a perfect solution for many applications from
light industrial to OEM.
