Product Specs

The 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.

Rated 5 out of 5 by from Great Encoder The coding for device was simple and it was easy to bolt together using the mount (sold separately) highly recommend

Rated 4 out of 5 by from Great but need to add an electrical schematic Great product and simple to integrate. The installation instruction need a proper electrical schematic and not just a wire color table. This would help clarify the open collector wiring, especial for those of us that have never used this type of quadrature output before. Most encoders are a simple single pulsed output.
