Touch Screens Ideal For Harsh Working Environments

Densitron has launched the DTS416 range of five-wire glass film glass analogue resistive touch panels for weather-, industrial- or instrument-grade touch display applications. The combination of traditional resistive touch with the addition of a glass cover lens is said to offer a cost-competitive, hardened sensor for use with a gloved hand, in a wet or harsh working environment, or when a passive stylus is required. The touch screens are said to work with thick gloves and when extremely wet, even with salt water.

Transparency is 80 per cent (typical); haze: 4.5 per cent; operating force < 100g; impact: 2.50 Dia. Steel Ball/67g; height: 100cm; durability: 10M times (knock test); scratch-resistant hardness: 7Mohs; drift: repeated calibration typically necessary. The touch panels work with a passive stylus in sizes from 5.7in to 12.1in standard; custom sizes are available on request.

The addition of a thin micro-sheet of glass bonded to the face of the film to the glass touch screen allows the Densitron DTS416 family of touch screens to offer 7Mohs scratch hardness, reducing scratches and abrasion. This approach produces a cost-competitive glass-surfaced touch screen suitable to an array of applications.

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.
