The X4 pen series was introduced with the X4 Smart Chip Stylus pen that came with the the XP-Pen Artist 12 GEN3 released in 2025.
XP-pen states:
IAF: 2gf
Max pressure: NOT STATED
My measurements
I have not measured it yet. When I get 3 of them I will measure.
But subjectively I would agree that IAF is close to what XP-Pen states and the mqx pressur seemed to be in the GOOD range (>350gf)
