Energy Chain Prevents Loops And Strained Cables

Igus is showcasing several new developments in power and data supply for robotic equipment at Automatica in Munich. The company has developed a universal module called Triflex RS, specifically for robotic applications in cramped conditions. The multi-axis robotic energy chain Triflex RS is guided parallel and close to the robot arm, preventing a loop forming or cables becoming strained at the robot head. The low-profile module can be mounted directly to the existing fastening points on the robot.

The moving end of the energy chain is attached to the sixth axis with a mounting bracket. This system allows general movements, meaning no specific programming is required. Thanks to its compact design, the system can even be used if there is a valve cluster or distributor box on the third axis. Special protective jackets are now also available. They protect the energy chain from liquid-metal splashes or other materials.

These are important in hot conditions such as in foundries, or for paint or sealing applications. The protective jackets are pulled over the energy chain and held by a Velcro fastener or elastic, ensuring the chain's long service life. Igus has developed the E4.1 energy chain for safe energy-supply on the seventh axis. It allows high flexibility and robustness in all applications. Assembly times can be reduced by up to 80 per cent thanks to improved opening and separating bridges.

A quick-locking feature ensures little force is needed for opening and closing, even for fully loaded chains. Special design, including the tongue and groove link joint, improves the self-supporting length by more than 20 per cent. The tongue and groove joint ensures high rigidity even with strong lateral forces.

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.
