SP1
Linear Position to 50 inches (1270 mm)
Rugged Polycarbonate Enclosure • IP67 Optional
Mounting Bracket & Optional Sensor Cover w/Connector
IN STOCK for Quick Delivery!
Compact String Pot • Voltage Divider Output
This compact stringpot with “voltage divider” output, pro-
vides ease-of-use and exibility for measurement ranges up
to 50 inches. Made of rugged polycarbonate, the SP1 ts in
small spaces, doesn’t need perfect alignment and ships with
a stainless steel mounting bracket to let the user easily ori-
ent this sensor in just about any direction imaginable.
The SP1 is available with a connector, mating plug and sen-
sor 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.
