Product Overview

A string potentiometer is a great way to detect position and travel for a robot mechanism. Spring-tension inside the enclosure ensures the string retracts as your mechanism does. The color of the enclosure will vary.

A portion of the proceeds of this sale will be given to Chap Robotics FRC team 2468, who developed and used this idea on their competition robots.

Included Hardware:
  • Three - 4-40 x 0.75" Screws (to seal the enclosure)
  • One - 4-40 x 3/8" SHCS (to capture the potentiometer shaft)
  • One - Retractable String component
  • One - Precision Potentiometer, 10 turn, 5Koh
  • One - String Potentiometer Enclosure
Note: With the retractable string provided, you will only be able to get about eight to nine turns out of the ten turn potentiometer. To get the full range, use the spring from the retractable string component and a 30" string instead.

    Broken out of the package

    Bought 2. Didn’t realize it would be 3D printed part. First one pulled string one time and it stayed out. Second one wasn’t giving reliable readings. Went with another type of sensor.

    Quality OK. I would have designed mounting base much larger to incorporate 4 screws and made housing thicker for unanticipated abuse.
