HSI Sensing’s AS9100 certification places us among an elite group of manufacturers who meet strict international requirements for traceability of raw materials, configuration management of parts and assemblies, and continuous qualification of people, processes, and equipment.
In addition, more than 80% of the sensors we design and manufacture have been custom engineered for our customers’ specific applications. HSI Sensing has a long list of customers in a variety of industries who have been successful because of the products we’ve engineered for them. We’re happy to provide these upon request.

We design in Solid Works®, a standard for our industry, and one that is highly compatible with multiple design packages.

Signing and adhering to legally-binding non-disclosure agreements is something our engineers do every day. We also offer custom part-numbering to ensure that your custom products never find their way onto any public price list or quote.

Obviously development time depends on the complexity of your device and your requirements. Customization of existing sensors–such as changing wire colors or connectors–can take as little as a few hours. Things like custom housings and lab work take longer, but not as long as you might think. We already have personnel, outside labs, prototype fabricators, and component manufacturers on standby to tackle your project at any time.

No matter what your requirements, we’ll estimate the development time and cost early-on, and keep you posted every step of the way. Keep in mind, is we are able to help out from the very beginning of the design process our turnaround time will decrease.

From day one, you’ll be partnered with a fellow engineer at HSI who understands the ins and outs of reed switch technology, who will listen to your requirements, and work with you on the project from beginning to end.

Our engineers collaborate with you to develop new products tailor-made for your application. Using our advanced machining, rapid prototyping, and custom molding techniques–along with testing the products in your application–we can shorten development time and prevent costly mistakes.
