Frequently asked questions

When would an extended lever actuator like on the 440G-T27172 be the preferred choice?

An extended lever actuator is beneficial when the machine guard or door is positioned at a distance from the safety switch, or when a longer reach is needed to ensure reliable actuation upon opening or closing the guard.
