SP1 Compact String Pot * Voltage Divider Output Linear Position to 50 inches (1270 mm) Rugged Polycarbonate Enclosure * IP67 Optional Mounting Bracket & Optional Sensor Cover w/Connector IN STOCK for Quick Delivery! 1.9" [48 mm] 1.9" [48 mm] 2.5" [64 mm] 2.3" [59 mm] COMPLETE SPECIFICATIONS Full Stroke Range Options 0-4.75, 0-12.5, 0-25, 0-50 inches Output Signal voltage divider (potentiometer) Accuracy 0.25 to 1.00% (see ordering info) This compact stringpot with "voltage divider" output, provides ease-of-use and flexibility for measurement ranges up to 50 inches. Made of rugged polycarbonate, the SP1 fits in small spaces, doesn't 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.
