An elevator car is provided and includes a car frame which translates along a guide rail during ascents or descents, a safety disposed along the car frame to selectively engage with the guide rail to selectively permit vertical elevator car movement, an electronic safety actuator (ESA) and a control system. The ESA actuates the safety and includes an ESA body secured to the car frame with horizontal maneuverability and defining a groove through which the guide rail translates during the vertical elevator car movement, a magnetic guide operably disposed within the groove to exert magnetic force on the guide rail and a sensor disposed within the groove to sense horizontal distance between the guide rail and corresponding portions of the ESA body. The control system controls the magnetic guide to exert a magnetic force in accordance with reading of the sensor to maneuver the ESA body horizontally.
