Stroke sensors are wire pull-out type length meters that are used for construction vehicles and industrial machinery. They have a proven results in the accurate measurement control of outriggers, booms, etc. They support many and varied strokes using two types of housing—one for short strokes (up to 3.1 meters) and one for long strokes (up to 10 meters)—and, with either type, the output resistance levels vary depending on the amount of wire pulled out.
