2 kgs is not very much, so i would probably consider arms that are slightly less industrial than Kuka, ABB, Fanuc, Denso and the like. However, 1.6m is pretty long and that may be hard to find in non-industrial arms.
Keep in mind there are many other factors to consider when choosing a robot arm. human safety, accuracy, repeat-accuracy, speed, workspace envelope.
for example, for relatively planar tasks, low payload, and very fast speeds, a delta configuration robot is best. Larger payloads, maybe a SCARA configuration is better. super large workspace, and planar tasks, perhaps a gantry is best. the point being, there is more than typical robot arms with spherical workspaces.
some of the arms listed below just won't survive the number of cycles industrial arms are typically driven to. the arms listed below are slightly more human safe than standard industrial arms, but probably less accurate.
all that being said, here are some more arms to consider:
As Pikey mentioned, Universal Robotics (http://www.universal-robots.com/) has some arms that might work.
You should also consider the WAM arm from Barrett (http://www.barrett.com/robot/products-arm.htm). It has been around a long time, and has a longer reach than many other arms.
A lighter duty arm which is very human safe is the Kinova arm: http://kinovarobotics.com/
Another that i have seen, but never touched is the Schunk arm: (http://mobile.schunk-microsite.com/en/produkte/produkte/dextrous-lightweight-arm-lwa-4d.html)
The HDT Arm might be overkill: (http://www.hdtglobal.com/products/robotics/Adroit_Manipulator_Arm/)
and of course Baxter for very light industrial use: http://www.rethinkrobotics.com/products/baxter/
