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.

Be sure to read the “Safety Precautions” on page 12.
