Non-Disclosure Agreements (NDA)
While it is not necessary for us to have an NDA in place to provide an estimate, NDAs are very common for our customers. We will work with you to quickly put one in place.

The following are the minimum specifications necessary for us to provide a ROM (Rough Order of Magnitude) estimate for your application. Please click on the RFQ button at any time when you're ready to begin working with us. The RFQ form will guide you through what’s needed to begin the specification and estimating process. Even if your idea is in the early stages, please use the RFQ page to get the ball rolling.

Just the basics to get started…

  • Number of channels (for example, a 110V AC circuit would require two channels)
  • Maximum current (including in-rush), maximum voltage and maximum resistance for each channel
  • Maximum length and diameter of the final package including clear bore
  • Maximum rotational speed
  • Expected operational life
  • Estimated order quantity
  • Application environment description
