Our team has an abundance of reed switch knowledge that sometimes seems hard to contain. But here on our blog our engineers and leadership share their abundance of knowledge to give you an inside look at how we use our work ethic, creativity and passion to push the limits of sensor technology everyday. Whether we are examining how we prototype projects or imagining ways that a reed switch could help us save a little water at home, we live sleep and breath sensor technology and want to share our insights with you.

Danger Danger: Designing for Hazardous Locations

A few weeks ago, I found out that I would be responsible for designing a new line of sensors that were to be certified for hazardous locations according to UL 1203. Fortunately, one of my coworkers had done this recently on a different product, so he knew how to point me in the right direction.

The “BSL” (Bi-Stable Latching) Form C, SPDT Reed Switch

I have spoken of some of our products being “amazing,” and I don’t want to use this term so much that I diminish its impactful meaning, but another one of our products that is in this same category that I am surprised most people are not aware of is the “BSL” (Bi-Stable Latching) Form C, SPDT Reed Switch.

Welding Tubes with the Mag-Probe

A customer came to us with a problem stemming from welding together a network of tubes in order to create a system for the delivery of gasses. When welding the tubes, the welder would plug the end, grind the end of the tube to be flat and then weld two sections together. This created two surfaces that could be mated flush.

How Does Temperature Affect Magnetism?

Magnets are used in daily life. They’re used in manufacturing, automobiles, security systems and electronics devices. Even the earth itself is a magnet. How does temperature affect the magnetism of magnets?

How Can I Increase Value?

We commonly have potential customers send us spec sheets for products asking, “Can you make this, and can I get a quote?” Our immediate response is typically, “Yes, and yes. What I really want to know is why. Why did the potential customer just ask that question?

Sputtering and HSI Sensing

Sputtering, or PVD, is the process whereby atoms are ejected from a source material that is to be deposited on a substrate. This process is done under a vacuum using an ultra-pure inert gas so impurities are nearly nonexistent.
