ELECTRONICS/SENSORS: The second generation KEYENCE GT2 “All-in-One” contact digital sensor, adopts 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. All measurement is performed in the compact GT amplifier requiring no PLC or external data processing.GT2 sensors are tough and rugged, and the cable’s IP67 water-resistant enclosure rating 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 50 mm (1.97 inch) 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.
The analog I/O card used with conventional sensors is not required for the GT2, which further reduces labor time, and total cost equipment status can be quickly checked by looking at the bar indicator that displays green when the data is within its limits and red when the values are out of spec.
Unlike industrial robots, which suffered a slight overall slump in 2012, service robots continue to be increasingly in demand. The majority are used for defense, such as unmanned aerial vehicles (UAVs); and agriculture, such as milking robots.
