Valuable information if you do query the signals of PGM grippers via inductive proximity switches:
Inside the jaws are countersinks to enable flooding the switches according their setting (depth).
This table shows the possible signals.
Depending on the size, some grippers also do offer C-Slots for inserting magnetic sensors.
