Schneider Electric 79421 MP Class 9007 Type AA-1 Roller Lever Arm A63 Roller Lever Arm

Schneider Electric Square D 9007 MP Class Roller Lever Arm AA-1 is a one-way roller lever arm designed for use with Class 9007 limit switches in MP-class control applications. The AA-1 variant features a metal roller with a 16 mm (0.63 in) diameter and a 6.3 mm (0.25 in) width, enabling smooth actuation and durable wear on the roller surface. This lever arm forms part of Schneider Electric’s 9007 family of limit-switch accessories and is specified as the AA‑1 one-way roller arm, a compact solution for installations requiring a compact lever with a rolling contact. Typical use cases include industrial automation where a moving component engages the roller to trigger a limit switch, such as on conveyors, presses, or packaging equipment, providing reliable, repeatable actuation with minimal mechanical backlash. The 9007 AA-1 designation denotes a specific lever-arm form factor within the 9007 catalog, designed to pair with 9007 limit switches to convert linear motion into electrical signaling without needing a separate actuator; the metal roller aids in consistent performance over many cycles in typical shop-floor environments.
