TE Connectivity Measurement Specialties' compact string pot with “voltage divider” output provides ease-of-use and flexibility for measurement ranges up to 50". Made of rugged polycarbonate, the SP1 fits in small spaces, does not need perfect alignment and ships with a stainless steel mounting bracket to let the user easily orient this sensor in just about any direction imaginable. The SP1 is available with a connector, mating plug, and sensor cover to protect against IP67 (wet) environments and a lower cost, “open” sensor version priced for both the budget conscious single piece user and the OEM alike. 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" electrical cable with a watertight rubber.
