Compact Encoder Operates In Harsh Conditions

SICK has introduced an absolute linear encoder for use in robotic handling systems, metal forming, cutting and processing PCB print and assembly and in flatbed printers and medical scanning equipment. The compact TTK70 encoder is designed for positioning robotics and machine tools or as a motor feedback system for linear motors. This magnetic encoder provides an alternative to fragile optical scales, with sub-micron resolution and an accuracy of +/-10 microns.

Featuring a small but robust read head, barely bigger than a matchbox, the TTK70 encoder is said to be simple to install and is ideal for applications with limited space. The TTK70 encoder comes with a range of interface options, including SSI/Sincos, Profibus, Devicenet and Canopen, facilitating integration into PLC-based installations. The encoder is also available with a Hiperface interface, enabling it to deliver dynamic linear motor feedback.

With a high level of resistance to dust, dirt and wet environments, thanks to magnetic operating principles and the IP65 rating, the TTK70 is reliable in harsh operating conditions. The TTK70 operates at up to 10m/s, making it suitable for rapid axes. The encoder is able to measure up to 4m in length using its absolute coded magnetic tape, which measures 10mm in width and up to 4m in length.

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.
