Allen-Bradley 801-ASC218 ROLLER LEVER LIMIT SWITCH NSFB 801ASC218

Description:

The Allen-Bradley 801-ASC218 Roller Lever Limit Switch (801ASC218) is used in industrial control systems to detect position, motion, or presence of moving mechanical components. Commonly installed on conveyors, machine tools, packaging equipment, and automated production machinery where mechanical end-of-travel or position sensing is required. Maintenance teams, OEMs, and system integrators use this limit switch for equipment replacement, machine safety functions, position verification, and restoring reliable mechanical sensing in automation systems. 

Applications:

The 801-ASC218 limit switch is widely used in industrial environments to monitor actuator travel, gate positions, conveyor indexing, and machine sequencing. Its roller lever actuator design allows reliable operation in manufacturing plants, material handling systems, food processing lines, and heavy machinery where durable and precise mechanical position detection is essential.
