Analyzing different proximity sensor technologies

March 25, 2021 By Aimee Kalnoskas

proximity sensors

Utilized as a no-touch method to provide either precise distance measurement to an object or simple “there/not there” logic, proximity sensors span a wide range of technologies, each offering their own set of operating principles, advantages, and drawbacks. Some of the most commonly found technologies in portable or small embedded systems include ultrasonic, photoelectric, laser […]

What are inductive proximity sensors, Part 2

February 19, 2021 By Bill Schweber

The first part of this article introduced the inductive proximity sensor. This second and final part looks at some more specifics of this sensor. Q: Are there different architectures and implementations? A: Yes, there are three basic types: 1) the magnetic elements alone are in the sensor. This separates the electronics from the sensing coils […]

What are inductive proximity sensors? Part 1

February 17, 2021 By Bill Schweber

inductive proximity sensors

Non-contact sensing of a nearby object’s linear or rotary position in an electrically and mechanically harsh environment is a common system requirement. There are several ways to meet this objective, including sensors based on the Hall effect, the magnetorestrictive effect, and magnetic coupling. One widely used approach is inductive proximity sensing, which is effective, accurate, […]

Wiegand sensors — proximity sensing with extra powers

December 16, 2020 By Mike Santora

PressPhoto#1-Wiegand-Sensor-Dec-2020

Wiegand sensors – tiny devices that use variations in an external magnetic field to generate electrical signals and energy – have unique properties that make them a useful option for proximity sensing systems. Wiegand sensors are built around small sections of Wiegand wire, a specially prepared ferromagnetic alloy that has a unique physical property. When […]
