Low profile touch sensor now 50% thinner
Elo TouchSystems has announced the new low profile infrared touch sensor and 4000S controller that use the company's CarrollTouch scanning infrared touch technology
Elo TouchSystems has announced the new low profile infrared touch sensor and 4000S controller that use the company's CarrollTouch scanning infrared touch technology At a mere 6mm (0.25") high-including the infrared opto-electronics circuitry and 2mm filter, the new 15" low profile touch sensor offers a profile approximately 50 percent thinner than that of the older model
The companion 4000S controller features an extended digital touch resolution of 4096 x 4096 with increased accuracy twice that of previous infrared products - resulting in a smoother touch response.
The new low profile touch sensor is designed to fit a variety of 15" LCDs, including the Sharp LQ150X1DG11, LQ150X1DG16, LQ150X1DG55 and LQ15X01W; Toshiba LTM15C423S and LTM15C428S; and LG Philips LM151X4-A3.
The 4000S controller has an RS-232 interface and is also supported by all Elo's standard drivers and SmartSet protocol.
The new low profile solution can be used in a wider range of environments, since it has an operating temperature range of -20C to 70C.
Elo's new low profile touch sensor and companion CarrollTouch scanning infrared 4000S controller are designed to provide an operator interface for use in applications such as medical instruments, process control, manufacturing monitoring systems, production automation, clean-room and manufacturing equipment, harsh office environments such as a 999 call centre, and indoor kiosks used for employee and job training.
The low profile touch sensor is also designed to meet NEMA 4 (IP65), which makes it particularly suitable for use in rugged environments.
"The new slimmer profile touch sensor is much easier for users to integrate with the display and provides a more compact form factor that will be particularly cost-effective and efficient in areas where space is at a premium," says Frank Shen, strategic market manager for Elo TouchSystems.
"In addition, the significant increase in touch points provides an operator interface that is far more sensitive and responsive." The slimmer shape of the new 15" low profile touch sensor makes it more easily interchangeable with Elo's existing AccuTouch (resistive) and IntelliTouch (surface wave) touch technologies, and the 4000S controller shares the same footprint as the AccuTouch and IntelliTouch controllers.
User feedback has determined 15 inches to be the most popular and cost-effective screen size in the display market.
Elo's 15" unit is, therefore, the first in this family of low profile touch sensors, with 12" and other units to follow shortly.
The low profile infrared touchscreen solution is available with three filter options: acrylic, glass or without filter.
CarrollTouch: Clear, Bright and Sharp Elo's CarrollTouch scanning infrared touch technology provides one of the highest light-ransmission rates in the market-up to 100 percent, based on filter option-so there is minimal loss of image quality or colour purity.
CarrollTouch technology provides parallax-free performance for the increasingly popular LCD displays.
Optional vandal- and abrasion-resistant filters are ideal for rugged applications.
The stable, "drift-free" character of infrared technology ensures a touch response that is always accurate, and the completely sealable units operate with any stylus - including a gloved finger - making them the ideal solution in industrial clean-room and medical environments.
