As the curtain has just risen on IAA Mobility 2023 in Munich on September 5, the leading Chinese provider of CMOS mmWave radar chips, Calterah, brings a most comprehensive portfolio of automotive radar SoCs at Booth A2-F31 of Mess München to the global audience. Figure 1 Visitors Showing Great Interest in Calterah mmWave Radar SoCs (please click on images to ...

CUI Devices is aiming at harsh environments with a waterproof MEMS microphone rated to IPx7 for water ingress. To be known as CMM-3424DT-26165-TR, the surface-mount device measures 4 x 3 x 1 mm and is compatible with reflow soldering. Microphone-wise, the acoustic port is on top and it is omnidirectional, according to CUI, with tightly-controlled sensitivity (-26dB ±1dB) and a ...

Rohm has developed Hall-based magnetic detectors for vehicle use. BD5310xG-CZ types are momentary (dubbed ‘unipolar’): turning on above a fixed south pole magnetic flux density and turning off below the same threshold (with a small amount of hysteresis) BD5410xG-CZ types are latching: turning on above a fixed south pole flux density, then remaining on until an equal north pole flux ...

Texas Instruments has picked the Hall effect for its latest isolated current sensor, and claims 50ppm/°C drift over temperature and ±0.5% drift over lifetime. Aimed at electric vehicle chargers and with versions available up to 75Arms, isolation in the TMCS1123 is rated at 1.1kVdc, and to withstand 5kVrms. “Assessment of device lifetime working voltages follow VDE 0884-11 for reinforced insulation, ...

Advancing electrical safety and energy efficiency with RCD and PMD technology integration. Bituo Technik, a Shanghai-based technology provider, has gained recognition as a leading supplier of Residual Current Devices (RCDs). Their expertise in RCDs is evident through the integration of type-A/F leakage current detection ICs and type-EV/B leakage current sensors into various electrical protection devices across Asia and Europe, including ...

HBK has added an IO-Link interface option to its U9C (tension and compression, right) and C9C (compression only, below left) force sensors. Described as miniature by the company, versions of the devices range across 50N to 50kN forces and are 26mm in diameter, except 46mm for the 50kN types. They are available as just the sensing bridge in its cylindrical ...

German sensor company Sick has announced a pair of colour sensors. “The newly-developed flagship, CSS, leads the way with the ability to distinguish even the slightest nuances in shade,” according to the company. “Its capability to identify subtle differences in surface structures and textures opens up wide-ranging applications in electronics components manufacture.” Variants with eight-pin M12 connectors have four pins ...

Why not use IoT-enabled sensors, using the LoRaWAN standard, for ‘ultra-early’ wildfire detection, asks Carsten Brinkschulte, co-founder and CEO of Dryad Networks? Wildfires contribute approximately 20% of the world’s CO2 emissions, equivalent to the combined emissions of automobiles, airplanes, trains, and ships. Even more concerning, these wildfires trigger a chain reaction in our climate, intensifying global warming by increasing the ...

Vishay has released an infra-red receiver designed to be used outdoors in light barriers and reflective presence detectors. TSSP93038 will work up to 1m reflectively or 11m in a light curtain when irradiated at 1.3mW/m2. The ambient light rejection strategy comes in two parts: the first is that the device’s peak sensitivity is to light at 940nm, and the second ...

HBK has added IO Link digital communication to a range of tension and compression force sensors. U9C sensors (pictured) measure tension and compression, and C9C sensors measure only compression. This article was republished with far more information here The sensors easing digital up-grades by having identical mechanical dimensions and threads to their analogue counterparts. “With a standardised interface to any ...
