Permanent Magnets Offer Very High Adhesive Force

Elesa has introduced a range of permanent magnets in sintered hard ferrite, Aluminium nickel cobalt (AINiCo), Samarium cobalt (SmCo) and Neodymium iron boron (NdFeB). This type of magnet can offer a range from low to extremely-high adhesive force, in the case of Neodymium magnets for example, making them suitable for location and temporary fixing of workpieces or panels or for sensor holding, for example, on conveyors or other machinery.

Moving down the scale, applications can be as varied as supermarket labelling, locating presentation materials, white boards, cabinet-door closure or magnetic filtration, for example, of metal particles in engine sumps or in machinery and equipment. These permanent magnets are available in flat format with/without steel/stainless housings in lacquer or thermoplastic coating and in cylinder format with brass-housed sandwich configuration. U Magnets and cylinder magnets in red lacquer, with pass-through facility, are also part of the standard series.

Retaining magnets are simple solutions to many problems of long-lasting fixing. Due to their structure they have one adhesive surface only, with poles optimised and arranged in such a way that the whole magnetic energy is focused on the adhesive surface. The effect in the area of the magnetic field is limited by a shielded system, avoiding the magnetisation of the surrounding objects.

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.
