Schneider Electric 9007-B9 Limit Switch Lever Arm

Schneider Electric’s Square D 9007B9 limit switch lever arm is a heavy‑duty replacement actuator designed for 9007 series limit switches. It features a 2-1/2 in (63.5 mm) long arm with a steel roller mounted on the outside of the lever, the roller measuring 1.38 in (35 mm) in diameter and 1/4 in (6.35 mm) wide for consistent contact with actuators across extended travel. The arm itself is zinc‑plated to resist corrosion in demanding industrial environments. This lever arm is specified for use with 9007 types T and FT limit switches, or Type C heads equipped with an S9 hub, enabling compatibility across the Square D/Telemecaneique 9007 family. It is suited to applications where a longer actuation stroke and a robust roller are beneficial, such as safety interlocks on conveyors, packaging machinery, or automated equipment where reliable engagement and signaling are required. The 9007B9 is a straightforward replacement part that preserves the established actuation geometry of 9007 limit switches, helping maintain consistent sensor triggering and machine response in routine industrial control installations.
