AH2-M/T, AH3-T, AH4-T—Air Module
1. Product Overview
Air modules provide air utility and are attached to the Master and Tool plates. When the Tool Changer is coupled,
the Master module passes the air supply to the Tool module for use by the customer tooling. Signicant forces are
encountered when using these modules. Assistance from the robot may be required to overcome these forces when
coupling the Tool Changer.
NOTICE: The Master and Tool modules contain self-sealing valves. Do not use self-sealing valves for
vacuum utility.

The Master and Tool modules contain pass-through ports and self-sealing valves. Pass-through ports release the
air or vacuum when the Tool Changer is uncoupled. Before uncoupling the Tool Changer, turn off the air pressure
or vacuum supply for the pass-through ports. Unlike pass-through ports, self-sealing valves prevent the air circuits
from discharging, which eliminates the need to close those circuits upstream.
