Keyence GT2 provides high-precision monitoring

Keyence (UK) product story

Jul 23, 2009
The second generation Keyence GT2 all-in-one contact digital sensor adopts a scale-shot system to provide the highest precision in its class (0.1um resolution, 1.0um accuracy).
It retains the 'No Error' feature from its predecessor, meaning no data is 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 six million times at a radius of 50mm.
It can be cut to length.
Linear ball-bearings covered by 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.
Simple tolerance setting at the touch of a pushbutton reduces the number of steps compared with conventional models.
A variety of displays, brackets and mounts (DIN-rail, compact panel, large display panel and pulse output) helps to accommodate user needs, simplifying amplifier installation and setup.
Large indicators on the display are convenient for setting up several units and also help to determine OK/NG connections at a quick glance.
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, warp, twist, maximum, minimum and average.
The analogue I/O card used with conventional sensors is not required for the GT2, which further reduces labour time and total cost.
Equipment status can be quickly checked by looking at the bar indicator, which displays green when the data is within its limits and red when the values are out of spec.
