In low power mode the AT42QT1040 draws only 31uA from a 1.8 VDC supply, allowing capacitive sensing to be added with minimal impact on batter...
OPTEK Enhances Family of Fluid Sensors with Automatic Calibration Circuitry
Providing design engineers with a simplified means of detecting the presence of fluid in transparent tubing, TT electronics OPTEK Technology has expanded its family of fluid sensors to include automatic calibration circuitry and a preset trip level feature. Designated the OCB350 Series, the fluid sensor with self-calibration circuitry requires only an optical device and power supply for operation. Like the original OPB350 Series sensors, these d...
IP67 Rated Pipe-Clip Temperature Sensor from Semitec
Semitec’s latest version of their CH pipe-clip temperature sensor is not only IP67 rated, it can also be supplied with twin NTCs to save the cost and time of fitting separate safety controls to hot or cold water systems.
Throttle Position Sensor in Hollow- and D-Shaft Versions
Vishay has announced a new throttle position sensor in hollow- and D-shaft versions that features Hall effect technology for applications in harsh environments. The Hall effect technology of the new 981 HE gives it the ability to perform in conditions involving high-frequency vibrations up to 20 G and shocks up to 50 G over a temperature range of –45°C to +125°C, providing a strong advantage over other technologies.
Honeywell's Hall-effect Magnetic Position Sensors Provide Enhanced Sensitivity In A Miniature Package
Honeywell has introduced its SS361RT and SS461R Bipolar Latch, Hall-Effect Magnetic Position Sensors, giving customers the opportunity to help reduce manufacturing costs. The SS361RT and SS461R sensors' enhanced sensitivity enables the use of less expensive magnets in some applications. The SS361RT sensor's very small footprint takes up less space on the printed circuit board, typically allowing for a reduction in costs. Additionally, the SS361RT...
STMicroelectronics Unveils Microcontroller-Based Sensing Capability
STMicroelectronics has announced the availability of its open-source capacitive touch sensing software library for its 8-bit STM8 MCU platform. Touch controls improve the look and feel of end products such as MP3 players, televisions, domestic appliances, or printers, compared to mechanical switches or membrane keypads. Using touch controls also lowers bill-of-materials costs while enhancing reliability because they have no moving parts. Typical ...
Radar sensor offers intelligent detection
Carlo Gavazzi has extended its range of devices for automated doors, lifts and escalators by introducing a family of compact radar sensors offering intelligent detection and simple, flexible installation. The RAD01 and RAD02 radar sensors utilise Doppler shift in a K-Band (24,125GHz) signal to detect motion towards or away from the device, and provide SPDT relay output which operates the door. Sensing is bidirectional in the case of the RAD01 or ...
Contactless rotary position sensor with dual outputs
Penny + Giles has announced the availability of a new low profile rotary position sensor with dual output channels. The SRH280DP, which incorporates a factory programmable Hall effect sensor, has two outputs that can be programmed independently. It provides reliable and accurate rotary position measurement in extreme environments and allows users to improve the safety and integrity of their control systems.
