Bunting Europe Announces Record Monthly Sales B


unting Magnetics Europe Ltd has had two consecutive months of record sales in September and October 2017. Bunting Magnetics is one of the world’s leading suppliers


of Magnets, Magnetic Assemblies, Magnetic Separators and Metal Detectors. The latest announcement of record monthly sales follows a prolonged period of growth.


Dave Hills, Bunting Europe’s Head of Sales, explained: “Despite media reports of a potential slowdown in


Curtiss-Wright extends rotary sensor family


of performance, safety and cost for OEMs designing vehicles and control systems. Sharing many features and benefits as the NRH300DP,


C


the NRH305DR incorporates two completely independent power supplies and output channels for full electrical redundancy, operating from a 5Vdc regulated supply. An 8mm low-profile sensor body and fully-encapsulated,


IP68/IP69K-rated design ensures exceptional levels of performance. Its separate magnet assembly can have a permissible air gap from 1.5mm-8mm (depending on magnet style) and accommodate >±2mm radial offset to ease setup/installation. Electronics can be set to 0.5-4.5V or 0.2-4.8V analog


voltage output ranges or one of three PWM frequencies. Analog output polarities can be set independently, with on- board diagnostic functions ensuring outputs are put into safe, pre-defined states should a sensor error be detected.

urtiss-Wright Industrial’s NRH305DR is a ‘no-contact’ rotary position sensor offering an optimal combination


manufacturing and continued concerns about BREXIT, we continue to see a growing demand for our products. This is the result of continued investment in our resources, both mechanical and personnel, whilst expanding our presence overseas. It’s been tough, but we continue to work hard to execute our strategic plan.”

Alicat Mass Flow and Pressure Instruments Now Offer EtherCAT Protocol A


licat Scientific’s line of mass flow, pressure and liquid instruments can now be configured with the EtherCAT protocol. Users of


Beckhoff PLCs for industrial automation can now connect Alicat devices with the high-speed and robust EtherCAT protocol. The speed and reliability of Alicat devices are particularly well


suited to vacuum coating processes, such as Atomic Layer Deposition and Chemical Vapor Deposition. All of the mass flow or pressure controller’s data, including: mass flow, volumetric flow, pressure, temperature, selected gas calibration, setpoint, and totalized flow can be output to a central PLC running a compatible automation protocol. For easy drop-in replacement of older industrial units, Alicat instruments are made to fit the same space as common industry mass flow controllers. All Alicat instruments are backed by NIST-traceable calibration, comprehensive technical support and a lifetime warranty.

Ricoh launches high performance Seamless LDO with low current consumption R


icoh Electronic Devices Company, Ltd. in Japan has launched the RP122 LDO Regulator, a remarkable Seamless LDO which addresses the typical issue of high performance LDOs with high current consumption at no load. The RP122 offers superb specifications whilst the current consumption at no load is kept to a very low level. Electronics designers often struggle with the question which LDO type to select for the circuit; one option is an LDO with low current consumption but the performance like ripple rejection and transient response speed are not impressive for these products. Another option is a high performance LDO but these have a high level of internal current consumption even when the output current demand is low. In 2005 Ricoh designed a smart solution called Seamless LDO technology. The RP122 features both LDO types and offers an impressive 90 dB ripple rejection, fast transient response speed and only 9.5 µA current consumption without output load. Additionally, it has a very low noise level at the output voltage, only 8 µVrms. These features are especially of an advantage for battery powered devices with noise sensitive circuits such as smartphones, tablets, digital cameras, RF modules, AD and DA converters etc.


The RP122 contributes to lower the total supply current


of the device and increases the lifetime of the battery, also it eliminates the need to switch between operating modes since the LDO adapts seamlessly to the output current demand. A number of protection circuits are integrated, a fold-back current limit circuit decreases the output current to approximately 70 mA in case of a short circuit, protecting the LDO and other electronic parts of the application for damage. The thermal protection shuts the LDO down when the junction temperature increases above 165°C. An inrush current limit circuit prevents any output overshoot and undershoot during the start-up

period. The inrush period is internally fixed has a maximum of around 700 µs. The RP122 has an optional auto-discharge function, this feature rapidly discharges the output capacitor once the chip is set to the standby mode. As for a stable operation small ceramic capacitors with a low ESR value and a minimum of 1.0µF can be used. The RP122 is available in a small sized 1.0 x 1.0 mm DFN(PLP)1010-4 and 0.64 x 0.64 mm WLCSP-4-P8 package.
