Pulse's Compact NFC Stamp Antenna Enables Integration with Penta-band Antenna in Single Module

Pulse, a Technitrol Company (NYSE: TNL), a worldwide leader in electronic component and subassembly design and manufacturing, is introducing its new NFC (near field communication) stamp antenna for mobile phones and portable wireless devices at electronica 2010, stand B6.323. This very small 15mm x 20mm x5mm antenna can be integrated with a main antenna so they both fit inside a 40mm x 21mm x 5mm module, enabling both 13.56 MHz NFC communication and frequency ranges of 824- 960MHZ and 1710-2170MHz for wireless connectivity using GSM and WCDMA in the same device.

"Despite its small size, our new NFC antennas open many possibilities for additional mechanical integration of speakers for audio, cameras, camera windows, flash, LEDs, and other options to the antenna module within these devices and can be tailored for each customer's design," explained Maritta Timosaari, director of sales and marketing for Pulse Mobile Products Division.

"Application possibilities for near field communications are almost endless because it enables the exchange of data from modules in close proximity within devices such as mobile phones. For example, the phones can be used to read RFID tags for payments, ticketing, security  identification, diagnostics, etc."

Pulse's NFC stamp antenna is especially well suited to function with small RFID (radio frequency identification) tags. It can read tags with diameters ranging from 15mm to 65mm at distances ranging from 5mm to 20mm, which cannot be read with a large loop antenna (size 110x42mm). When comparing the performance with rectangular tags measuring up to 86x53mm, the performance is comparable to that of a large loop antenna (size 110x42mm).

The NFC antenna operates at a frequency of 13.56 MHz, has an H-field of 1.5A/m, and a return loss of -25dB. The main antenna is a penta-band antenna. For the 824-960MHz frequency rangeit has an efficiency of 58 percent/-2.35dB peak, 27/48 percent/ -5.7/-3.1dB band edges, and a return loss of -5.2dB. In the 1710-2170 MHz frequency range it has efficiencies of 59 percent/ - 2.3 dB peak and 40/45 percent/ -3.9/-3.4dB band edges with a return loss of -5.1dB. Both antennas have an impedance of 50 ohms and have operating temperatures ranging from -40 to +85 degrees Celsius. The separate NFC antenna can be integrated in the device back cover with a snap-fit structure also available.

The NFC antennas are RoHS compliant. They are packaged in trays or as requested by the customer. Engineering samples are available.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications.
