Modular Vision Devices For Tough Inspection Tasks

Cognex has introduced Advantage Image Engines, a range of programmable vision devices for original equipment manufacturers (OEMs), suitable for challenging inspection applications. The Advantage Image Engines range is claimed to offer excellent 1D barcode and 2D Data Matrix code reading and includes a full suite of Cognex vision tools. The vision devices can be integrated into commercial and industrial equipment.

The devices feature a modular design that provides a good level of user control over lighting, communication and optics. According to David Gantt, vice-president of sales for OEM Vision Engines, the new code-reading devices offer vision and enable OEMs to detect defects, locate features and analyse parts. The Advantage Image Engines range uses the same code-reading algorithms as those found in Cognex industrial ID readers. The company's decoding software enables the fast reading of 1D and 2D codes on almost any surface at any speed, including difficult-to-read codes caused by low contrast, scratches and voids or reflections.

Cognex also offers a library of industrial-grade vision tools. High-accuracy Patmax object location software provides part and feature location, ensuring reliability and repeatability under challenging conditions, according to the company. Three product configuration options are available: engine only, engine plus interface board and engine encased in housing. A modular lens design provides a choice of optics to accommodate varying working distances and field-of-view requirements.

The Advantage Image Engines range of OEM image engines offers the ability to power and control external lighting. All of the vision devices feature built-in Ethernet with industrial protocols to facilitate the communication of data and images (USB and RS232 are also supported). OEMs are able to design and configure their applications using Cognex Dataman setup tools, In-Sight setup tools or a C++ programming library.

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.
