iC-Haus has created a high-speed sine-to-digital signal conditioning interpolation IC for magnetic or optical position sensors. “Linear scales and angular sensors can benefit from higher resolution and accuracy, enabling an outstanding measurement precision, a faster motion speed or an improved control quality for drives,” claimed the company. By combining analogue and digital processing, the IC, called iC-NQE, takes in analogue ...

TDK has announced two series of Pb-free bead thermistors. “Both series are Pb-free and can measure temperatures between -40 °C and +155 °C,” according to the company. “At room temperature, their maximum power dissipation is 60mW. Both series are available with different rated resistances between 1kΩ and 100kΩ and different R/T characteristics [see table]. After 10,000h at +70°C, the deviation ...

Vishay has revealed a high-speed and high-precision inductive rotational position sensor. As the device, RAIK060, uses induction, it “isn’t sensitive to magnetic environments, allowing it to be used close to electrical motors”, according to the company. The specs are impressive: Up to 10,000rpm rotational speed, with custom versions going higher, and 0.044° (≥13bit) accuracy at 25°C with ±1 LSB output ...

Mouser is shipping a CO2 sensor for air quality monitoring that is “ideal for applications that must meet standards like California’s Title 24, RESET Grade B, WELL, UBA and ASHRAE 62.2”, it said. Made by Renesas, the single-channel, non-dispersive infra-red module is called RRH47000 and has automatic baseline calibration for measurement from 0 to 5,000ppm. Also in there are temperature ...

Singular Photonics has spun out of the University of Edinburgh to offer two ultra-sensitive camera chips based on SPADs – single-photon avalanche detectors. Both have in-sensor digital signal processing. Development has been lead by Professor Robert Henderson, head of Edinburgh’s CMOS Sensors and Systems Group, and a pioneer of SPAD-based image sensors: he co-designed one in 2005, and in 2013 ...

At SPIE Photonics West in a fortnight, Vision Components will demonstrate Raspberry Pi 5 software drivers for its VC MIPI Cameras, which also cover the Raspberry Pi Hailo TPU HAT. “Embedded vision applications with and without AI can be implemented, using all VC MIPI Cameras and the Raspberry Pi processor board,” according to the German company. The drivers will be ...

Melexis has been delving into the intricacies of measuring the temperature of cooking pots on induction hobs, and has created an IC specifically for the job. “Customer requests initially sparked the development of the MLX90617,” said Melexis marketing manager Joris Roels. “However, the challenges of working with relatively small signals of infrared at short wavelengths made us question its feasibility.” ...

Sensor Technology is created a torque transducer for power take-off (PTO) shafts in agriculture, construction and industry. Called SGR570, it is a range that will cover 1Nm to 2kNm. Sealing will be to IP65, and there will be “analogue and digital outputs, the same as the SGR520, configuration software, PC connectivity, user-configurable limits and an anti-rotation eye hook”, according to ...

Kaman Precision Products has introduced a high-reliability version of its KD-5100 eddy current distance measuring module, intended to be used for nanometre resolution feedback where moving mirrors are used to steer lasers, for example. Bandwidth is 0 to 5kHz. The module works with pairs of eddy current coils, connected by flying leads, positioned on the mirror assembly so that the ...

Researchers at UK universities have developed a wearable ‘sticker’ that can monitor and detect changes in people’s breathing rates. The non-invasive sensor-based system – using a capacitive sensor – can efficiently discern changes even when not in direct contact with the skin. It represents an alternative to chest-band or face mask systems, which can be uncomfortable for use over long ...
