Manufacturing/Engineers
One of our customers has used this in construction of some of their label printers.  Others have used it in counting devices, and also when adding a port to the back of an arcade gaming machine to allow connections.  It's a high quality product that will offer years of good connectivity quality.  Once you install it you never have to worry about it again.
