Advantech’s industrial-grade isolated RS-232 to RS-422 or RS-485 converter is now available from the company’s e-store. With no change to associated computer hardware or software, the device, called ADAM-4520A, transparently converts RS-232 signals to RS-422 or RS-485. It “allows users to take advantage of RS-422 and RS-485 on systems originally equipped with RS-232”, said Advantach. “It can extend the communication ...

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 ...

Toshiba has announced twelve 650V silicon carbide (SiC) Schottky barrier diode (SBDs) based upon its 3rd generation technology. In this series, called TRSxxx65H, according to the company a new Schottky metal has been employed, and the junction barrier structure has been changed to lower the electric field compared with the 2nd generation to reduce leakage. Versions with nominal maximum continuous ...

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 ...

Diodes has introduced three-pin SOT23 automotive qualified Hall effect magnetic sensing ICs that latch on with one magnetic pole and off with the other. The open-drain output of AH1711Q, AH1712Q and AH1713Q will be switched on when applying a magnetic south pole of sufficient strength near the top of the package (perhaps with north below the package), while a north ...

Nexperia has created a dc-dc converter chip designed to extend the life of 3V primary coin cells in bursty IoT applications, such as those with pulsed radio transmitters. “The IC’s designed to extend the life of a typical non-rechargeable lithium coin cell battery while also increasing peak output current by up to 25x compared to what a typical coin cell ...

Texas Instruments has created a series of precision current monitors with digital outputs, for use across power rails from  -100mV to +85V, at up to ±78.64A. In each case, an internal ΣΔ ADC measures current across an integrated sensing resistor, as well as voltage and temperature – communication with the host if via I2C. The ICs need a separate supply ...

STMicroelectronics has created its first galvanically isolated gate driver for GaN transistors. Called STGAP2GS the wide body SO-8W packaged single-channel driver can work with rails up to 1.2kV. The package is 5.8mm long by 10.3mm across pins tips, with 7.5mm between leg roots on either side of the isolation barrier. A separate supply (above), or dual supplies (left) if a ...

Nexperia has entered the IGBT market, with a 600V 30A device, to be followed by 40, 50 and 75A types. “IGBT is a relatively mature technology,” said the company. “Nonetheless, the market for these devices is expected to grow in line with the increased adoption of solar panels and electric vehicle chargers. Nexperia’s 600V IGBTs feature a carrier-stored trench-gate field-stop ...
