Inductive components for industrial applications
SMP Sintermetalle Prometheus introduces at this year’s Electronica in Munich inductive components for industrial applications, for example frequency converters. The components are low-loss, have good EMC characteristics and a space-efficient design.
8042-01 Submersible IEPE Accelerometer
Measurement Specialties is now in full production of its Model 8042-01 Submersible IEPE Accelerometer certified for >100 meter depth. This sensor is available in ±10g, ±80g and ±500g dynamic ranges with an operating temperature range of -20 ºC through +80 ºC, non-linearity of ±1% and shock protection to 5000 g’s.
Replacing the Candle in Candelabra
LED lamps are now displayed prominently in retail stores as plug-in replacements for standard incandescent lamps. Fitting the protection and constant current drive electronics required by LEDs within the neck of standard size bulbs is a squeeze - especially for lights using a T8 tube or a compact Edison-screw based design. In this article, Power Integrations presents two compact, efficient bulb replacement design ideas.
New Bosch MEMS acceleration sensors Fifth generation of sensitive crash detectors SMA58x and SMA59x in SOIC14n housing
Bosch has introduced the next generation of peripheral acceleration sensors for passenger protection systems in vehicles – the fifth since 1996. The key features of the new digital sensors include a wide measurement range of between ±120 g and ±480 g and the choice of communication via the SPI or the PSI5-V1.3 interface. Peripheral sensors are located at the outermost points of a vehicle's engine compartment, at the sides, or at the rear, thu...
TDK releases new TFM family of thin-film metal power inductors
TDK has developed four new series of miniature, low-profile thin-film metal power inductors featuring up to twice the rated current and half the DC resistance of comparable ferrite inductors. The new TDK TFM family is available in four form factors, including IEC 1608, which at 1.6 x 0.8 x 1.0 mm3 is the world’s smallest metal power inductor.
“Contains Murata Innovation” theme at Electronica 2012
Murata invites visitors to Electronica to come to their stand, B5 – 107, and view products and demonstrations. With the theme of “Contains Murata Innovation”, all the demonstrations and new products will be based on a variety of concepts suitable for consumer, industrial and automotive applications.
Making sense from sensor fusion data
Sensor fusion is becoming a popular technique for increasing the accuracy and useability of data from MEMS sensors in smartphones and other consumer devices. In essence, the technique involves combining data from multiple sensors to produce a faster and more accurate representation of what is happening outside the system.
Processing power targets sensor fusion
The complex algorithms used by platforms such as the iNEMO Engine to combine the outputs of multiple sensors obviously require processing power; in the iNEMO Engine development boards this is done on a separate ST microcontroller. But why is this ‘sensor hub’ configuration becoming the norm rather than using central processing resources such as the application processor?
PITTMAN high speed brushless/slotless DC micromotors from Mclennan
As part of its distribution partnership with USA motion specialist AMETEK, Mclennan Servo Supplies offers complete sales support for the recently announced PITMANN range of specialist high-speed brushless/slotless DC micromotors.
TI 2.5-A isolated gate driver doubles device lifetime, extends temperature range
Texas Instruments Incorporated today introduced an isolated gate driver for insulated-gate bipolar transistors (IGBTs) and MOSFETs that is 40 percent faster than equivalent optical gate drivers. The input TTL logic and output power stage in the ISO5500 are separated by a capacitive, silicon dioxide (SiO2) isolation barrier that doubles the lifetime of the device compared to optocouplers and magnetic isolators. When used with isolated power suppli...
