Motion Sensors
MEMS motion sensors, hall effect sensors and inductive sensors. This category combines all the sensors used to sense motion, vibration, acceleration, rotation and position.
Motion sensors are revolutionary devices designed to detect movement in their surrounding environment. Whether it's for enhancing security measures, automating everyday tasks, or monitoring activity in a given space, motion sensors play a pivotal role in modern technology.
Motion sensors find applications across various domains, from home automation to industrial settings. In smart homes, motion sensors are utilised to automate lighting systems, turning lights on or off based on occupancy, thereby enhancing energy efficiency and convenience. Moreover, they serve as integral components of security systems, triggering alarms or activating surveillance cameras upon detecting suspicious movement, thus bolstering safety measures.

Inductive Rotary Encoders – A Low-Cost Alternative to Optical Systems
As the boundaries between the real world and the virtual world blur, the significance of sensors grows. Rotary encoders are particularly important because they convert the angular position or motion of a rotating shaft or axle to a digital output that can drive a control loop.
Inductive encoders, with their flexibility, robustness, and ability to deliver high resolution with careful design, are an increasingly practical, lower-cost alternative to optical encoders in many applications.

NCS32100 - Industrial Dual Inductive Rotary Position Sensor
onsemi has been developing inductive sensors for automotive for over 20 years and have now adopted a new approach that is designed for high-accuracy and high-speed industrial applications. Benefits include:
- High-accuracy (typical spec +/- 50 arcsec, precision alignment accuracy +/- 15-20 arcsec)
- High reliability (not sensitive to temperature, vibration, magnetic fields or contaminants such as liquids, dirt and dust)
- Low cost (taking the supporting circuitry and PCBs into account)
- Flexible sensor diameter options (current reference design uses 38mm diameter sensor, but there are other sensor options)
- High speed (up to 100,000 RPM)
