Low Cost Bluetooth Low Energy Proximity Key Fob is Smaller Than a Credit Card and Can Run for a Year off a Slimline CR2025 Coin Cell

Developed by world-leading wireless sports & fitness monitoring developer and manufacturer – Dayton Industrial – that also developed the world’s first production-ready Bluetooth low energy heart-rate belt last year – the proximity key fob employs an ultra low power Nordic Semiconductor µBlue™ nRF8002 Bluetooth low energy chip and will support practically any proximity-based property location or security application

Ultra low power (ULP) RF specialist Nordic Semiconductor ASA (OSE: NOD) today announces that Hong Kong-headquartered Dayton Industrial Co. Ltd – a world leading OEM/ODM (Original Equipment/Design Manufacturer) of wireless monitors and associated products (such as watches and bike computers) for top global sports & fitness consumer brands – has now announced a Bluetooth® low energy proximity key fob based on Nordic’s µBlue™ nRF8002 System-on-Chip (SoC) that is less than half the size of a credit card.

The nRF8002's class-leading ULP performance and size will enable the Dayton Bluetooth low energy proximity key fob to run for around a year from a regular 3V CR2025 lithium coin cell battery under typical (daily) usage conditions while featuring an extremely slim (0.5cm-thick) and compact (4.9 x 3.2cm) plastic sensor housing that features a single push button and two submerged LED status lights (one red to signal alerts, and one green to signal pairing status) within a product that weighs less than 40g. There are also additional micro-vibrator and buzzer alert options.

This production-ready product platform will allow OEMs and developers to develop a whole new range of both standard (Bluetooth v4.0 profile-based) and non-standard (uniquely developed) proximity, property location and security applications (‘apps’) for use with devices that employ Bluetooth v4.0 wireless technology such as the latest iPad and the iPhone 4S.

Bluetooth low energy is a hallmark feature of the latest Bluetooth v4.0 specification and if certain qualification requirements are met can be used to develop Bluetooth Smart devices (such as wireless sensors, peripherals, and accessories) compatible with any Bluetooth Smart Ready hub product (e.g. A smartphone, tablet/computer, and other gadget).

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.
