Vishay Intertechnology Releases New Series of Surface-Mount TransZorb® TVS in SlimSMA™ Package

Vishay Intertechnology, Inc. (NYSE:VSH) today introduced a new series of surface-mount TransZorb® transient voltage suppressors (TVS) in the SlimSMA™ DO-221AC package. SMA6F series devices offer a very low profile of 0.95 mm, high surge capability to 600 W at 10/1000 µs and 4 kW at 8/20 µs, and excellent clamping capability.

The TVS devices released today are 50 % thinner than devices in the traditional SMA package, yet are footprint compatible and offer 50 % higher surge capability at 10/1000 µs. The SMA6F series’ low clamping voltages of 9.2 to 31.4 at 10/1000 µs and 13.4 to 36.8 at 8/20 µs are 3 % to 9 % lower than current TVS devices in the SMB package.

With their compact size, SMA6F TVS are designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning in space-constrained consumer, computer, industrial, and telecommunication applications. Typical end products include hard disks, hot swap computer and telecom cards, and slim LCD TVs and monitors.

The SMA6F series consists of 16 TVS devices with stand-off voltages from 5 V to 20 V. The devices offer a temperature range from - 55 to + 175, provide ESD capability of 15 kV (air) and 8 kV (contact) in accordance to IEC 61000-4-2 Level 4, and meet the MSL Level 1 standard, per -STD-020, LF maximum peak of 260 °C.

Ideal for automated placement, the TVS devices are RoHS-compliant and halogen-free.

Samples and production quantities of the new SMA6F series are available now, with lead times of eight weeks for large orders.

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 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.

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.
