The ZCH is a rugged, incremental encoder that converts shaft rotation into a current sinking pulse train
All units are packaged in a rugged cast aluminum housing with a gasketed, rear aluminum cover. The 3/8 inch (9.53 mm) diameter heavy duty stainless steel shaft and sealed, lifetime-lubricated precision ball bearings are preloaded for minimum end play and rated for continuous use up to 6000 RPM. The ZCH is designed to meet NEMA 13/IP54 environmental requirements. The unit is supplied with 10 feet (3 M) of PVC jacketed 3-wire, 22 AWG cable with stranded shield wire and 100% foil shield coverage.
The ZCH can be direct-coupled to a machine shaft by means of a flexible bellows, spring or rubber sleeve type coupler, etc., that allows for axial and radial misalignment. The unit can also be coupled with instrument timing belts and pulleys or gears. The housing may be rigidly face-mounted with the 4, #8-32 threaded holes. The 3-wire shielded cable exits through a cord connector.
