Device Measures Optical Loss in Fibre

GAO Fiber Optics has released a fibre-optic visual light source suitable for measuring the optical loss in fibre in the testing and maintenance of telecom, CATV and other fibre-optic applications. Used together with the company's 5304 fibre-optical power meter, the new device, model 5204, provides a precise testing solution for optical networks.

This fibre-optic visual light source, which is part of GAO's Light Source range of products, provides one to six wavelengths of highly stable output, including 650nm visible red light, 1,310/1,550nm wavelengths for single-mode fibre and 850/1,300nm wavelengths for multi-mode fibre, as well as other optional wavelengths. It offers typical output power of 0dBm at 650nm, -7dBm at 1,310nm/1,550nm and -20dBm for light-emitting diodes (LEDs).

Its modulation frequencies are CW, 2Hz at 650nm and CW, 270Hz, 1kHz and 2kHz at other wavelengths. It features one-touch switch operation, a backlight LCD display for night operation and low battery power indication. It has an auto-off function after 10 minutes of idle time. The fibre-optic visual light source is powered by alkaline batteries that provide 45 hours of continuous operation and also has an AC power supply.

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.
