String Potentiometer SP Series
Model: 
SP Series

 These compact linear position precision string potentiometers range from 0-50 inches (1270mm).

Available in 5 different types:

  • Voltage Divider - SP1
  • Voltage Divider (with 40" electrical cable) - SP2
  • 4 ... 20mA (2 wire) - SP3
  • 4 ... 20mA / 0 ... 10 VDC - SPD
  • Incremental Encoder - SE1 

Voltage Divider - SP1

  • Range: 0-4.75 (120mm)
  • 0-12.5 (317mm)
  • 0-25 (635mm)
  • 0-50 inch(1270mm) 

This compact string pot with “voltage divider” output, provides ease-of-use and ?exibility 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.

Voltage Divider (with 40" electrical cable) - SP2

  • Range: 0-4.75 (120mm)
  • 0-12.5 (317mm)
  • 0-25 (635mm)
  • 0-50 inch(1270mm) 

The SP2 String Pot is a compact, economical and water resistant device that utilises 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-inch electrical cable with a watertight rubber strain relief. The SP2 has been compactly designed for tight spaces and high cycle applications and generously allows for measuring cable misalignment. 

4 ... 20mA (2 wire) - SP3

  • Range: 0-4.75 (120mm)
  • 0-12.5 (317mm)
  • 0-25 (635mm)
  • 0-50 inch(1270mm) 

The SP3 is a compact, economical string pot that provides a user selectable 4-20mA or 0-10 VDC output signal. Simply install this sensor using the handy mounting bracket and connect the appropriate wires for the desired output.

4 ... 20mA / 0 ... 10 VDC - SPD

  • Range: 0-4.75 (120mm)
  • 0-12.5 (317mm)
  • 0-25 (635mm)
  • 0-50 inch(1270mm) 

This compact stringpot provides the ultimate in ease-of-use and flexibility. This sensor fits in small spaces, doesn’t need perfect alignment, mounts in just about any direction imaginable and has a unique circuit that lets the user choose 4-20mA or 0-10VDC output on the fly. 

Incremental Encoder - SE1 

  • Range: 0-25 (635mm)
  • 0-50 inch(1270mm) 

The SE1 is the digital encoder version of our compact String Pot series. The SE1 is an economical and durable device that utilises a flexible cable, a spring-loaded spool and an incremental optical encoder to detect and measure linear position.
