SM1 Miniature String Pot

Linear Position to 25 inches (635 mm)
Fits In Tight Spaces • Handy Mounting Bracket
Polycarbonate Enclosure • Free Release Tolerant

With it’s ultra compact design the SM1 is the perfect solution when tight space is an issue. At just a little over an inch across, this miniature stringpot offers full stroke measurement ranges from 2½ to 25 inches. A precision plastic hybrid 10K-ohm potentiometer delivers a precise voltage divider output signal that is linearly proportional to the travel of the spring-loaded measuring cable.

Constructed with a rugged polycarbonate enclosure and free-release tolerant, the SM1 is the perfect solution for the OEM and single piece user alike.
