By CIOReview | Thursday, August 6, 2015

ALISO VIEJO, CA: Semiconductor solutions provider, Microsemi has launched industry’s first Inductive sensor interface integrated circuits (ICs) based on inductive sensing technology. The model named LX3301A is based upon Linear Variable Differential Transformer (LVDT) architecture for implementation and installation on Printed Circuit Board (PCB), and is designed for automotive and industrial applications.

The device is more susceptible to external magnetic fields and metal objects in close proximity as it uses inductive sensing technology which helps in wireless transformation of energy. This technology thereby improves its immunity towards noise and interference, enhancing its potential to replace currently utilized Hall-effect sensors in the marketplace.

"Inductive sensing is an emerging technology which can replace Hall-effect sensing in a wide variety of mechanical motion sensing applications, and provides significant improvement in temperature stability, enhanced reliability and safety, and reduced system costs for our customers" says Shafy Eltoukhy, Vice President and Business Unit Manager at Microsemi.

The device has got range of applications in the field of control systems and industrial automation, specifically linear displacement measurement. This makes it capable for fluid level sensing, gear positioning for transmission actuator position and proximity detection. It can be utilized in manufacturing industry for angular motion measurement where it can be dexterous in robotic arm positioning, rotating shaft positioning, pedal positioning and rotary controls.

The additional features of this sensor include contactless sensing embedded with 32 bit processing engine with 12kb program memory making it highly reliable. Experienced automotive support team will ensure successful adoption of the system which will model two sensor input channels with integrated demodulator and an internal oscillator with frequency range of 1-5 MHz.
