10 to 20W DIN Rail DC-DC converters are under 26mm thin CUI’s latest family of compact DIN rail DC-DC converters is housed in a slim 76x31.5x25.8mm DIN-Rail package with all electrical connections easily accessible via screw terminals. The family’s 47 modules, across three series PYB10-DIN, PYB15-DIN, and PYB20-DIN have an output range of 10 to 20W with input ranges of 9 to 36 Vdc or 18 to 75 Vdc for batterydriven applications. The devices operate reliably in the -40 to +85°C temperature range. The PYB family is available in single output (3.3, 5, 12, 15, or 24 Vdc), dual output (±5, ±12, or ±15 Vdc), and in 15 and 20 W versions, triple output (3.3/±12, 3.3/±15, 5/±12, or 5/±15) models. Outputs are fully regulated to within ±0.5% for overall line input conditions and ±1.0% for all load conditions. Input to output isolation of 1,500 Vdc is provided across the range of models. The PYB series delivers efficiencies reaching 91%. Single output 15 W and 20 W models offer an output trim that allows ±10% nominal output adjustment. All parts include a remote on/off feature. Protections include continuous short circuit, over current and over voltage. The PYB series meets CISPR22/EN55022 Class B standards with limited external components. An optional heat sink is also offered on most models for improved thermal performance. CUI www.cui.com CO2 sensor module offers maintenance-free long-term stability The sensor module EE893 from E+E Elektronik allows accurate and long-term stable CO2 measurements in demanding OEM applications. Thanks to its small size and low power consumption, the EE893 can be used in both hard-wired sensors and battery operated devices such as wireless transmitters, hand-held devices and data loggers. environmental influences. Aging effects are compensated automatically . The multiple point CO2 and temperature adjustment ensures high accuracy over the entire temperature working range. Measurement intervals can be set individually according to the requirements of the application. The device offers a measuring range of 0 to 10,000 ppm; the readouts are provided across a digital E2 interface.

The milestone was achieved in close collaboration with a leading device manufacturer using the company’s Development Toolset for early stage testing. MIMO is a key feature in LTE-Advanced, Advanced MIMO antenna configurations where both the base station and the device are equipped with multiple transmit/receive antennas are leading to an increased need for device testing prior to market launch. 4x4 DL MIMO capable devices require greater antenna separation/isolation and are therefore used in devices with larger form factors such as phablets, laptops with inbuilt modems and set-top boxes, as well as in various automotive applications. Anite’s capability to test 4x4 DL MIMO follows its earlier success in demonstrating Carrier Aggregation of two component carriers of 20 MHz each, resulting in Category 6/7 downlink data rates of 300 Mbps. ‘Complex antenna configurations such as 4x4 DL MIMO require advanced testing capability. Anite’s leading product roadmap and its collaborative engagement with key industry partners enable device manufacturers to accelerate their designs of LTE and LTE-Advanced products’, says Paul Beaver Products Director at Anite. Anite www.anite.com Flush-mountable infrared LED delivers remote control functionality Osram Opto Semiconductors has introduced the company’s first flush-mountable infrared LED which enables remote control functionality to be incorporated in a lower profile than ever before. The T-shaped SFH 4140 Midled protrudes 0.6 mm above and below the board thereby offering remote control functions in a small space. The compact side-looking T-shaped Midled offers high radiant intensity and protrudes fractions of millimeters from the board. An infrared transmitter can therefore now be integrated in extra-thin smartphones or tablet computers. For the first time, Osram Opto Semiconductors has succeeded in sinking a surface-mountable infrared LED in a pc board. The LED is the T-Midled SFH 4140. The T-shaped transmitter takes up 4.6 mm2 of board space and emits a focused beam to the side. The beam angle of +/-25 degrees is created by an integrated reflector – a real plus point in terms of space requirements. The SFH 4140 produces an impressive 50 milliwatts per steradiant (mW/sr) as its typical radiant intensity from 100 mA so it achieves the ranges needed for remote control functions. The wavelength of 940 nanometers is also perfect for meeting the requirements of this application. This component is Osram Opto Semiconductors’ contribution to the trend of turning smartphones and tablet computers into universal remote controls. If the device is equipped with the appropriate infrared transmitter diode then the diode can be controlled with a suitable app. Osram Opto Semiconductors www.osram-os.com 48 Electronic Engineering Times Europe May 2014 www.electronics-eetimes.com
