DescriptionThe ZMD Series miniature length sensor is compact in size and easy-to-use, designed for light to medium duty sensing applications. It features a built-in springloaded torsion arm that provides a simple-to- adjust torsion load, allowing the unit to be mounted in almost any orientation, including upside down. Using a 6" circumference wheel, the ZMD can be used on almost any surface, while operating at speeds up to 3000 feet per minute. The housing is a durable, conductive composite material that will eliminate static build up. Whether you need to measure speed, position, or distances, the ZMD series contact rotary sensor is the ideal solution.
