The KP-3 is compatible with most any CNC control with an input for a probe.
The KP-3 itself is a kinematic probe which simply breaks continuity through the precision kinematic seat ( a super accu-
rate switch) when tripped. So, said another way when the probe is not tripped there is continuity through the switch, and
when the probe is tripped the switch opens breaking the continuity.
The operating voltage of the KP-3 is 5 to 24 Vdc
If you cut into the 3.5 mm Barrel plug cord there are three wires as seen below.
KP-3 wiring and use with other CNC controls
The KP-3 itself has an output signal is that of a normally closed switch. (NC= When the probe touches a surface the
switch opens.)
Black = Probe Trigger Signal

Red = Probe Detect signal (

)
(This is used for detecting if the
