Digital Contact Sensor Showcases Scale Shot System

July 27, 2009

The second generation Keyence GT2 "All-in-One" contact digital sensor is said to have adopted the world's first scale-shot system to provide the highest precision in its class (0.1μ resolution, 1.0μ accuracy). Maintaining the "No Error" feature from its predecessor, no data will be lost due to rapid spindle movement during production line and other high-speed applications, according to the company. All measurement is performed in the compact GT amplifier requiring no PLC or external data processing.

GT2 sensors feature a cable that has a IP67 water-resistant enclosure rating that helps prevent or reduce swap outs in select harsh environments. The sensor head cable uses a flexible robot cable that can withstand continuous bending up to 6 million times at a radius of 50mm (1.97"), and can be cut anywhere to length. Linear ball bearings covered by a strong rubber, encase the spindle to ensure a long service life by eliminating wear and abrasion damage. Detecting durability extends up to 20 million times.

A single unit can connect up to 11 sensor heads for a space saving compact installation. When several amplifiers are connected, the GT2 Series enables automatic calculation simply by selecting a calculation mode. Versatile detection modes support all applications such as measuring the degree of flatness, thickness, warpage, twist, maximum, minimum, and average.

The analog I/O card used with conventional sensors is not required for the GT2, which is said to further reduce labor time and total cost.
