Five Key Applications of Hall Effect Sensors

Over 100 years ago, the Hall effect was identified. However, it is only within the last three decades that practical uses of this effect have been developed. Some of its first applications include use in microwave sensors in the 1950s and solid-state keyboards in the 1960s. Since the 1970s, Hall effect sensing devices have found their…

Magnetic Switch Selection: Reed Switch vs. Hall Effect Switch

Reed switches and Hall Effect switches are both considered magnetic switches since their properties change when exposed to a magnetic field. Strictly speaking, however, Hall Effect switches are transducers since they convert magnetic energy to electrical energy—they can be used as switches with some additional circuitry. Reed switches are true magnetic switches since they close…

How an Environment Affects a Magnetic Switch

A magnetic switch is a device that closes an electrical circuit when exposed to a magnetic field. The switch stays open until it’s impacted by magnetism. This switching mechanism is ideal for underwater deployment and conditions where electric sparking could trigger explosions or fires. How Reed Switches Work in Different Environments A magnetic reed switch…

Selecting a Magnetic Switch for Your Next Design

Magnetic switches, as their name suggests, are devices that allow or disallow the flow of current based on the presence of a magnetic field. There are several types of magnetic switches, each possessing specific characteristics that lend themselves to different applications. When designing or selecting a magnetic switch, it is essential that parameters such as…

Snow? What Snow?

Portland Metro area suffers from the big Winter Blast. After receiving unusually large amounts of snowfall for our area, we went through a long freezing period. This lasted about a week and a half in total. Many schools and offices shut down over this period. Even large shipping companies in our area, including UPS, did…
