Autotex Films Ensure High UV Resistance for Tablet PCs

Kienzle Systems' membrane keyboards and graphic displays have long been regarded as among the leading products in European and international markets. Based in Bad-Friedrichshall, Germany, the company has most recently been working on new developments for portable PC systems, particularly the design and production of hard-wearing data entry devices, housings and components for Tablet PCs used in a wide range of outdoor applications.

The latest generation of heavy duty tablet PCs has been developed specifically for extreme outdoor use, with protection from vibration and water spray, in areas that include land registry and surveying assignments, outdoor mapping, industrial and construction sites, and even rescue operations. Data entry is intuitive, via an active pen, and poses no problem even when wearing protective gloves. The main requirement for using such mobile equipment, however, is ergonomic design and excellent legibility even in direct sunlight.

In particular, the high levels of UV light in such exterior applications rapidly affect the performance of conventional membrane keypads, leading to discolouration and embrittlement of the surface layers. As a result, Kienzle Systems have specified Autotex XE from MacDermid Autotype for the overlay film for Tablet PCs.

This advanced polyester film combines the well-known properties of polyester with outstanding UV resistance. Autotex XE is a high-quality textured polyester film consisting of a polyester base and a flexible, chemically bound, textured hard coating.

Björn Kienzle at Kienzle Systems explains that, "The uniform, textured surface, extraordinary anti-scratch properties and of course the high UV resistance that prevents premature yellowing and embrittlement, make Autotex XE the ideal material for these demanding outdoor applications."

He goes on to say, "We create a huge number of exclusive variants for easy-to-operate front-end designs. Apart from customer-specific keyboards for all parts of industry, measuring and control technology, utility vehicles, industrial PCs and medical engineering, we now produce data entry systems for surveying and geological applications.

Our customers in each of these demanding market sectors demand maximum performance, reliability and consistency. To achieve the high quality standard for which our products are well known, we therefore need a supplier with equally progressive quality products. With its industrial films, MacDermid Autotype is the market leader in the field of polyester overlay films, and the right partner for us“.

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.
