Abstract

An actuator includes a piston and a housing. The piston includes a piston shaft that is configured to reciprocate within a chamber of the housing. The actuator includes a gland electrically coupled to the housing. The gland forms at least a portion of a first end of the chamber. The actuator also includes a first conductor positioned in the chamber. The first conductor is coupled to the gland and to a first side of the piston to electrically couple the piston to the housing.
