Compact String Pot • Voltage Divider Output

ORDERING INFORMATION

This compact stringpot with “voltage divider” output, pro-

vides the ultimate in ease-of-use and exibility for mea-

surement ranges up to 50 inches. Made of rugged polycar-

bonate, the SP1 ts 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 di-

rection imaginable.

The SP1 comes in two dierent versions: one complete

with a connector, mating plug and sensor cover to protect

against IP67 (wet) environments and the other, a lower cost,

open sensor design priced for both the budget conscious

single piece user and the OEM alike.
