Touch Switches Promise Enhanced Visibility and Performance

KYOCERA Display is offering a new capacitive touch switch based on technology experience gained in the smart phone market. This capacitive touch switch detects variations in position and command. This technology offers the highest standard of optical performance with ease of design. Capacitive touch solutions focus on a number of applications, including: handheld terminals, gaming, medical equipment, point-of-sale and mobile applications to enable human-machine interface.

The new touch switch solutions provide outstanding clarity and simplify the design. The new capacitive touch switch technology eliminates air gaps and reduces the number of layers. An improved visibility results from less reflectance and higher transparency of the display image through the touch panel and allows for a thinner display sensor stack up. (0.5mm—0.7mm thickness in viewing area). The new solutions not only offer high optical performance but also are more compact and light weight. The structure is very robust with lifetime of approximately 100 million touches. The surface is not damaged by exposure to fluid and is easy to clean.

In addition, the new touch switch solution from KYOCERA Display offers a transparency of min. 95 percent and a reflection of less than 15 percent. The operating temperature is -20°C - +70°C.

Products based on the capacitive touch technology are currently available for demonstration and design-in purposes in 3-inch (T-55149) and 3.5-inch (T-55343) display sizes. Additional sizes in 5.7-inch (T- 55265) and 6.5-inch (T-51750) will soon be available. Our touch switch solution is available alone or with out display product integrated to the touch screen.

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.
