Linear Position Measurement up to 125 inches (3 meters)

Designed for Outdoor / Wet environments

The SR1M is part of a series of rugged, low-cost, high perfor-

mance string pots built for wet environments and outdoor

applications. Designed for the rigors of outdoor construc-

tion equipment or the demands of a factory oor, the SR1M

is the perfect low-cost solution for OEM and stocking dis-

tributors.

What sets this sensor apart from other string pots, is the in-

ternal programmable digital circuitry that gives the custom-

er a one-size-ts-all approach for many applications. The

SR1M ships factory calibrated to the full 125-inch (3-meter)

measurement range but the output signal can be easily re-

scaled to match any stroke down to 1 inch (25 mm).
