ITT Connector Handles Multiple Data Feeds

ITT Interconnect's Veam CIR-M12 Databus connector has been designed to enable a variety of different data types to be transmitted between coaches in modern mass transit systems. ITT mounted its Quadrax QXM12 contacts into FRCIR connector circular bayonet series hardware.With this design, four conductor wires and the associated braid from shielded cables are integrated into the QXM12 contact.

A special plastic insert groups multiple QXM12 contacts and their cables into a single connector. With this connector, designers can incorporate data transfer from Ethernet, MVB, WTB and video lines, according to VG95234 (where applicable), within the same connector, handling data feeds such as engine diagnostics, brake controls, environmental conditioning, passenger display systems, networking and lighting control. The CIR-M12 Databus connector contacts are rated at 3A (maximum current for 1ms is 10A); operating voltage is 100V DC and insulation resistance is 10Gohm.

Mechanically, the insert is formed from thermoplastic material according to NFF16-101-NFF16-102, conforming to UNI-CEI 11170 (I2F2) and UL94-V0. The coupling gasket is made from silicone rubber, while other parts are produced in flame-retardant rubber. The metallic parts are aluminium alloy with black epoxy-urethanic varnish and are RoHS compliant. The connectors withstand operating temperatures of -40 to +125C.

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.
