Numatics S1011320032AMO Reed Magnet Assembly

The NUMATICS S1011320032AM0 Reed Magnet Assembly (ZE-876992-5) provides precise piston-position sensing for pneumatic cylinders and actuators using magnetic reed switch technology. Designed for industrial automation, it detects piston position and feeds discrete signals to PLCs, control relays, and automation systems for sequencing and machine control operations. Mounting options include cylinder groove or external cylinder mount depending on the actuator series, and the electrical interface can be flying leads or connector termination (configuration dependent). The device delivers a discrete NO/NC switching output based on configuration, activated by the magnetic field from the cylinder piston magnet, with millisecond response and long-life non-contact operation that minimizes mechanical wear. Commonly used with NUMATICS pneumatic cylinders, NUMATICS valve manifolds, and NUMATICS automation systems, it supports applications in packaging equipment, material handling, assembly machinery, and industrial automation lines where piston-position feedback enables end-of-stroke detection and process control. Common replacements include NUMATICS magnetic reed cylinder switch assemblies (same cylinder family), AVENTICS pneumatic cylinder reed sensors, and SMC D-A series auto switches.
