ED Series
Overview
ECO Series (ED)

The ED Series is a fixed stop indexer designed for cleanroom applications. Standard features include a corrosion resistant nickel plated housing, plated shafts and stainless steel covers for smooth surfaces to avoid debris buildup. An optional right angle geared motor with on demand stop sensor package is available. Grease filled, the housing can mount in any position and totally maintenance-free. This high accuracy indexer is offered in miniature to medium housing sizes with a large output motion selections.

Features

Wide Product Lineup
Available as a stand-alone indexer, or with a choice of factory-mounted stepping motor,
No Maintenance
Sealed grease lubrication eliminates the need for oil changes.
Cleanroom Options
Options are available for preventing rust and corrosion in harsh operating environments.
