Simple Assembly of Polymer Optic Fibres

The new assembly tool from HARTING significantly simplifies and speeds up the assembly of polymer optic fibres while also achieving low attenuation levels. An electrician who lays cables as required in automation has very little recourse to a preassembled system cable. Consequently, this environment calls for processing methods that allow quick assembly of an optical data cord with reproducible attenuation levels. The conventional cutting of the fibre with subsequent grinding and polishing is time-consuming and there not always the appropriate option for the electrician.

HARTING's new assembly tool allows both precise cutting and stripping. Both single optical fibre conductors are simultaneously stripped and cut with a circular knife in the duplex procedure. The front face of the optical fibre is cut to such high precision in this procedure that there is no need for subsequent polishing. In order to guarantee that each cut is precise, the circular knife is pre-clocked with each processing step. A mechanical counter permanently integrated in the gripper registers the number of steps carried out. One cutting unit can be used for more than 1,200 cuts. At the end of its service life, the cutting tool blocks. The user can replace it with a new cutting unit in a simple step. A visual display signals how many cuts can still be made, allowing arrangements for a new cutting unit to be made in good time. The tool consequently guarantees reliable assembly with reproducible cutting and attenuation results.

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.
