Schneider Electric 9007-TUB3 Roller Lever Limit Switch

Schneider Electric's Square D 9007-TUB3 Roller Lever Limit Switch is a rugged, industrial-grade limit switch designed to sense end-of-travel positions on machinery and trigger control actions. It features a die-cast zinc housing for durability and a 600 VAC (DC capable) rating at up to 12 A, making it suitable for demanding applications in conveyors, presses, and automated equipment. The switch employs a SPDT contact arrangement (one normally open and one normally closed) to provide both output states from a single actuator input, and it uses a roller lever actuator for smooth engagement with moving parts. The 9007 family supports a variety of lever-arm options, including the 9007R18 (0.75 in roller), 9007R19 (1 in roller), and 9007R20 (1.38 in roller), allowing you to tailor travel and actuation force to your setup. Mounting flexibility is enhanced by inside/outside offset lever-arm configurations, enabling precise alignment on diverse machines. In many configurations, this model is offered with maintained (latching) or spring-return operation to match your control philosophy, and certain variants provide a 1/2 in NPT conduit connection for wiring. These attributes—heavy-duty construction, solid electrical ratings, versatile lever-arm options, and multiple actuation configurations—make the 9007-TUB3 a purpose-built choice when reliable end-of-travel sensing is required in harsh industrial environments.
