BEI Express Encoders®

Get the Right Encoder...Right Away!

Whether you need product for a prototype or need to get a system up and running, Express Encoders® may be just the ticket.

Express Encoders are popular configurations of our standard model encoders that can be built and shipped quickly. With six package styles (four incremental and two absolute) to choose from, over 2,000 different configurations - that will meet just about any need - are available as Express Encoders.

Express Encoders ship in three days or less. We pay the freight for UPS 2nd Day Delivery when shipping to an address in the continental United States. Certain models in the Express line are kept in stock for same day shipment (when ordered by 2:00 PM pacific time).

Versions of incremental Model H25®, Model H20®, Model HS25 and Model HS35, and absolute Model H25® and Model HS35, listed below, are available for express delivery.
