Just like the SM1, the SM2 is the perfect sensing solution when tight space is an issue. With its rugged compact design, handy mounting bracket and a 40-inch electrical cable for easy signal connection, the SM2 is the perfect solution for the OEM and single piece users alike. 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 voltage divider output signal that is linearly proportional to the travel of the spring-loaded measuring cable.
