UHF RFID System Uses 865-870MHz Band

IFM Electronic's UHF RFID system uses the 865-870MHz band (there is also a 902-928MHz variant for the US market), offering flexibility on a standard platform. For the European range there are five different antennae. The more compact ultra-low and low range will read tags in close proximity without seeing adjacent tags, making them the most selective. A mid-range antenna will pick up data from a tag up to 2m away, while the long-range options can read a tag at 7m.

Bulk reading of the standard tags is also well within the capability of the new system, which is based around the worldwide ISO 18000-6C, EPC, Global Class 1 Gen 2. The information read from the tag is presented to the outside world through a simple Ethernet TCP/IP standard interface. The software for configuring the system reader with up to four antennae attached comes supplied with IFM's DTE800 reader unit.

Further integration into an automated system is made possible with coordinating input and output signals on the reader. So a read sequence can be triggered by an external event and sorting carried out directly via the DTE read unit. All units, readers and antennae come housed in industrial designs featuring IP65 and standard industrial connectors. A selection of co-axial leads for the antennae, Ethernet patchcords and M12 power and I/O connectors form part of the overall offering.

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.
