Absolute draw wire encoders from Sick Stegmann can measure as far as 50 meters while holding resolution within 0.025 mm. They find applicability on everything from cranes to excavators and are robust enough to survive the harshest conditions, says sales and marketing manager, Scott Hewitt. Compared to line-of-site linear positioning with lasers, draw wire transducers exhibit great mounting flexibility. The draw wire can be routed over pulleys to negotiate the tightest corners.
