Elo TouchSystems has a new low-profile infra-red touch sensor and 4000S controller that use the company's CarrollTouch scanning infra-red touch technology.

Elo TouchSystems has a new low-profile infra-red touch sensor and 4000S controller that use the company's CarrollTouch scanning infra-red touch technology.

At a mere 6mm (0.25in) high - including the infra-red optoelectronics circuitry and 2mm filter - the new 15in low-profile touch sensor offers a profile approximately 50% 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 infra-red products - resulting in a smoother touch response.

The new low profile touch sensor is designed to fit a variety of 15in 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, as it has an operating temperature range of -20 to +70C.

Elo's new low profile touch sensor and companion CarrollTouch scanning infra-red 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 slimmer shape of the new 15in 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 15in to be the most popular and cost-effective screen size in the display market.

Elo's 15in unit is, therefore, the first in this family of low profile touch sensors, with 12in and other units to follow shortly.

The low-profile infra-red touchscreen solution is available with three filter options: acrylic, glass or without filter.
