Schneider Electric 9007DA-4 Lever Arm Actuator

Schneider Electric's Square D 9007DA-4 lever arm is a heavy-duty limit-switch lever arm designed for use with 9007-series limit switches in industrial automation. The arm length is 2.5 inches and is cast from zinc for durability, while a nylon roller—1 inch in diameter and 1/4 inch wide—is mounted in an outside-roller position to engage the actuating mechanism smoothly. This 9007DA-4 lever arm is specified for use with Square D 9007 limit switches (Osisense family), delivering repeatable actuation and reliable signaling in applications such as machine guards, safety interlocks, and control-panel assemblies where an external lever arm is required. Standard dimensions across the 9007DA family include a 2.5-inch lever, 1-inch roller diameter, and 1/4-inch roller width, with an outside-roller position to suit common mounting patterns and actuation linkages, and the combination of a robust metal lever and a precise nylon roller helps maintain consistent switch actuation across numerous cycles while resisting wear in demanding environments.
