MD4 user inputs

Richard 9 years ago in Master modules / MD4 updated 7 years ago 2
I want to use multiple MD4 units on a new project but the problem is in our application the user may be wearing gloves so I am not sure a touch screen is useful. My first idea was to put a CAN open tactile button pad by the side of the MD4 unit but have come up with a blank.
I have tried - Grayhill - Graf-Syteco and powerkey so far who do have keypads but they do not have a size or shape currently in production that fits nicely alongside the MD4 (7").
Does anyone have any ideas?
