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).

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
