Enabling Grip Switch
A4EG
Enabling Grip Switch with Distinct Feel
for Three Easily Discernible Positions
■ The difficult task of configuring safety circuits is now easily
achieved by combining the A4EG with the G9SX-GS.
■ In addition to the standard models, the lineup also includes
models with an emergency stop switch and models with a
momentary operation switch.
■ An optional Holding Key (sold separately) provides a versatile
method for selecting modes.
■ Equipped with conduit connector.
