Sanyo Denki can obtain NEMA Standards, MIL-Standards, BSMI, CE, CSA, cUL, and UL (UL1778, UL1446, UL924, UL508, UL60601) safety standards. The process involves a variety of production and quality tests to ensure your satisfaction. We also help support customers to obtain their industry’s certification of SEMI, DOT, and FDA. 

How It Works


Custom projects start with a SANYO DENKI sales person gathering data on the opportunity from the customer.  This information will then be reviewed by our engineering team who will evaluate the data to determine if the project is achievable.  If approved, rough order of magnitude (ROM) costing, as well as an estimated timeline, are provided for review by the customer.  Upon engagement, a written Scope of Work will be drafted and agreed to by both parties before moving forward with a project.

Customization and ruggedization are at a higher cost and greater lead times compared to the standard “off the shelf” product.  These cost increases come from low volume manufacturing costing as well as initial Non-Reoccurring Engineering fees (NRE).  Custom projects generally require a minimum order quantity to make them cost-effective. With Sanyo Denki’s committed custom projects, you will have a manufacturing service period on the contract.
