By Karsten Köhler, Business Development Manager at TDK-Micronas The auto industry is amid two transformative trends: the gradual transition from internal combustion engines (ICE) to electric motors and drivetrains and the ongoing development of driver assistance and self-driving features. Sensor technology is famously integral to both trends, but electrification and assisted driving account for only […]
Applications
Understanding electret condenser microphones
Electret condenser microphones (ECMs) are widely used in audio applications due to their small size, low cost, and high sensitivity. They operate using a permanently charged diaphragm and backplate, eliminating the need for external polarization. This makes them ideal for use in consumer electronics, hearing aids, and professional audio equipment. Their ability to deliver a […]
Capacitive sensors feature integrated LED bar graph and IO-Link protocol
Carlo Gavazzi Automation has introduced two new capacitive sensor series: the CA18CB..IO and CA30CB..IO. These sensors feature an integrated LED bar graph and IO-Link communication capabilities. The sensors incorporate an LED bar that displays ON/OFF stability status. Green LEDs positioned on either side of the yellow switching LED indicate signal stability and dust accumulation levels. […]
Sensor offers ±1K accuracy across -40 °C to +150 °C operating range
TDK Corporation launches B58101A0851A000, the first in a new line of immersion temperature sensors (ITS), designed specifically for EV powertrain cooling applications. This highly responsive, fully sealed NTC thermistor is engineered to provide fast and precise temperature control, e.g., for oil-cooled systems. Oil cooling is anticipated to become the dominant temperature management method in the […]
Hall element sensors detect motor rotation and current
Diodes Incorporated introduces its first series of advanced InSb Hall element sensors for rotation speed detection and current measurement in consumer applications such as laptops, mobile phones, joysticks, and in motors found in various home appliances. In industrial applications, they are designed for use in position encoders and commutation of brushless motors and fans. The […]
How are VCSELs used in biomedical sensors?
Vertical-cavity surface-emitting lasers (VCSELs) are used in biomedical sensors because they emit highly focused, coherent light at specific wavelengths, enabling precise detection and analysis of biomolecules. Applications include blood oxygen level monitoring, optical coherence tomography (OCT) for imaging tissue structures, fluorescence microscopy, and analysis of live biomolecules in lab-on-a-chip systems. VCSELs offer a third option […]
What sensors are needed to fly hypersonic missiles?
Maneuverability and guidance systems, not just raw speed, are key differentiators for hypersonic missiles. That requires aerodynamic pressure sensors, optical sensors, inertial sensors, space-based tracking, infrared sensors, and more. All are combined into a single guidance system using sensor fusion. This article reviews the sensor types for hypersonic guidance, navigation, and target acquisition systems. Hypersonic […]
Square shaft torque sensors enable direct integration with fastening tools
Sensor Technology Ltd has released the new SGR525/526 Torque Sensors featuring square shaft ends for integration with fastening applications. The sensors are engineered for torque measurement in power tools, test equipment, industrial machinery, and precision fastening operations without requiring additional adapters. The SGR525/526 series delivers real-time torque measurement data with high-precision specifications. The design incorporates […]
What sensors are needed to counter the hypersonic threat?
The old analogy of missile defense as “hitting a bullet with a bullet” no longer applies. The muzzle velocity of bullets is “only” 1,800 mph. A hypersonic missile travels at about 3,900 mph, twice as fast. A bullet can’t catch a hypersonic missile! To implement a hypersonic missile defense, it takes a comprehensive suite of […]
60 GHz measurement sensor provides multi-environment detection capabilities
Hosiden has announced a new millimeter-wave distance measurement sensor that expands potential use cases with additional functionality. The design incorporates control circuits, wireless communication interfaces, battery power, and internal firmware within a waterproof housing. The package offers streamlined implementation options to system integrators and service providers. The module features mounting flexibility on top or bottom […]
