Impact Devices has a record of providing a high quality products utilized in many different applications by our customers around the world. Our solenoids have been employed in the testing of turbines and generators for General Electric and have been used in assembly equipment and robots manufactured in Europe and Canada. Our solenoids are shipped worldwide and we are able to ship a range of quantities. We are committed to quality: we test the product performance of each solenoid and we only use UL recognized components.

The specification sheet below displays the typical information needed to design and manufacture a new solenoid design. Once designed, we model and test new solenoids in our facility in Wheat Ridge, Colorado, before shipping them to our customers for application testing. The spec sheet then serves as the documentation for the ongoing manufacturing of that design, once the customer has confirmed that the new product performs to the necessary expectation.
