PDA Panache resistive styluses are for use on touch screens that respond to any touch, not just fingers. Resistive screens have a plastic surface the stylus depresses to make contact.
These are the most common industrial touch screens.
The tip of a Resistive screen stylus is made from a special plastic, (Acetal or Delrin) and should be about .8mm in radius.
PDA Panche resistive touch screen tips are available in EasyView Orange, or Black.
