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.
