Bluetooth Module Has 1,000m Range

2001 Electronic Components has released the WT41 long-range Bluetooth module. The WT41 offers a range of 1,000m between two WT41 Bluetooth modules and utilises Bluegiga's radio frequency design methodologies. The WT41 comes with Bluegiga's Iwrap firmware providing users with simple software integration without the need for the Bluetooth protocol or profile development.

Iwrap is an embedded Bluetooth stack firmware for Bluegiga's Bluetooth. It enables a powerful command interface to manage Bluetooth operations. Standard HCI over UART/USB is available as well as the possibility to develop custom firmware. Key features of the WT41 include Bluetooth 3.0 + EDR compliant, fully integrated Bluetooth radio with Bluetooth stack and profiles, plus the option of high-efficiency chip antenna or U.FL connector.

The WT41 modules has a transmit power of +20dBm and implements a low noise amplifier, improving the modules sensitivity down to -90dBm. Supported Bluetooth profiles for the WT41 using Iwrap firmware include SPP, DUN, HFP, HSP, HID, AVRCP, DI, PBAP, OPP, FTP and HDP, along with standard HCI over UART or USB. The WT41 is targeted at numerous applications including M2M, medical and industrial devices, point-of-sales systems and automotive diagnostic units, where performance and reliability of the data or audio connection is essential. The link remains connected even in the most demanding situations, avoiding sudden no coverage situations.

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.
