Draw-wire linear position sensors

Posital’s MDW draw-wire linear position sensors, with analog voltage or current output, are for use in low-cost analog-control systems. Programming operating parameters, including range and sensitivity, is through a pushbutton and LED interface.

The sensors are an alternative to conventional multiturn potentiometers. Based on a noncontacting magnetic- measurement technology, they are not susceptible to the wear or corrosion that degrades a potentiometer’s accuracy. The sensors provide instantaneous measurement of linear displacement over a 0 to 16-ft (0 to 5-m) range.

The encoder’s rugged enclosures, seals, and bearings protect internal components for operation in harsh conditions. The sensor’s heavy-duty spools are rated for over 1 million draw/rewind cycles.
