NEW SPACE-SAVING PULSE GENERATORS FROM SUPERTEX FOR ULTRASOUND APPLICATIONS

Supertex (Nasdaq GS: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced HV7360 and HV7361, high voltage, high speed ultrasound pulser ICs with fast return-to-zero (RTZ) outputs. The ICs are designed as space-efficient alternatives to discrete solutions using MOSFET drivers and discrete complementary MOSFET arrays for medical ultrasound applications. The ICs combine controller logic interface circuitry, level translators, MOSFET gate drive buffers, and high voltage, high current P- and N-channel MOSFETs as the output stage in compact, 22-lead, 5mm x 7mm, LFGA packages. HV7361 also features an integrated transmit/receive switch.

HV7360 and HV7361 both feature 2.0ns matched delay times, up to 35 MHz operating frequency, and +/-2.5A source and sink currents with up to +/-100V of pulse swing. The direct AC coupling topology of these ICs not only eliminates two floating voltage supplies, it also makes designing the circuit board much easier.

“The simple to use HV7360 and HV7361 add to Supertex’s already substantial family of products for the medical ultrasound imaging market,” states Jimes Lei, Director of Application Engineering for Supertex. “These ICs offer designers the
benefits of a compact, 5mm x 7mm, LFGA package.” HV7360 and HV7361 are available in 22-lead LFGA packages (HV7360LA-G and HV7361LA-G). The parts are RoHS compliant. Samples of HV7361LA-G are available from stock. Consult Supertex for samples of HV7360LA-G. Lead-time for production quantities is 4-6 weeks. Pricing is US$4.40 each for HV7360LA-G and US$5.09 for HV7361LA-G, both in 1K quantities.

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

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.

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…

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. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
