TiNi Aerospace, Inc.: Products: ERM Selection Guide

> EJECTOR RELEASE MECHANISM PRODUCTS

The ERM is inherently a scalable device which, so far, has been designed into the following sizes.

          • E500
          • E1000
          • E2000
          • E4000

In each case the model number reflects the maximum actuation load (lbf) which the ERM is capable of.
The tables below show an overview of the specification relating to each of these sizes. See individual specification sheets for further data or request a detailed procurement specification from TiNi Aerospace.
