Spring Terminal Connector Suits Transportation Use

EAO is offering a new spring terminal connector technology for the Series 04 switch range, which can be used in transportation, mechanical engineering and process-automation applications. The Series 04 PIT (push-in terminal), which features a spring terminal connection from Phoenix Contact, is said to reduce assembly times by up to 70 per cent compared with screw terminals. It offers a more reliable, secure connection in combination with a very high resistance to vibration and the cable connection is accomplished without any tools.

To achieve a secure connection, users need simply push the stripped wire end into the spring terminal, which applies the correct pressure to maintain a secure connection over the lifetime of the switch. Depending on the application, not even bootlace ends (core-end sleeves) are needed. PIT offers protection against contact according to IP20. The EAO Series 04 has been upgraded with the following three products with push-in terminal technology: a snap-action switch element (gold/silver), a slow-make element (gold/silver) and a lamp block.

The elements are stackable, providing the flexibility to use up to six contacts per switch. The push-in terminals connect to any of the Series 04 actuators, including square and round pushbutton versions, two- or three-position lever switches, key lock switches, emergency stops and large-headed buttons. Most of these products are available with LED illumination. Series 04 equipment offers front protection IP65 and is rated 500V AC. It fits into 22.5mm mounting holes (raised mounting) or 30.5mm round and square cutouts (flush mounting). The operating temperature is -25 to 55C. All products comply with international standards, including CE, RoHS, CB - EN/IEC 60947-5-1, UL (pending for PIT), NFF 16-102, CSA, CCC, GOST and German Lloyd.

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...

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...

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.
