Selection Guide for AirTAC Cylinders with Built-in Magnet Ring & Magnetic Models

I. Functions and Features of AirTAC Built-in Magnet Rings

An AirTAC cylinder built-in magnet ring is a permanent magnet element installed inside the cylinder piston. Its primary function is to generate a stable magnetic field during piston movement, working in tandem with an external magnetic sensor switch (magnetic inductive sensor) to precisely detect the piston's position and send feedback signals to the control system (such as a PLC).

Key Features:

• High Magnetic Sensitivity: Accurately triggers sensor switches (such as the CMSG and CS1 series), preventing missed signals or false triggering.

• Temperature Resistance & Low Decay Rate: Made of high-quality magnetic materials, ensuring minimal magnetic loss even under long-term, high-frequency reciprocating motion and heat generation.

• Compact Embedded Design: Perfectly embedded within the piston without taking up extra stroke or space.

II. Common AirTAC Magnetic Cylinder Series (Model Identification)

In AirTAC’s model numbering system, built-in magnet rings are typically represented by the letter "S" (Magnetic type) in the cylinder model code:

• Standard Magnetic Cylinder Series (e.g., SCS Series)

  • Features: Suitable for medium to heavy-duty industrial automation drives. The piston features a built-in strong magnet ring, paired with dedicated mounting rails/brackets for magnetic sensors.

• Miniature Magnetic Cylinder Series (e.g., MAS / MAL-S Series)

  • Features: Compact size, commonly used in light-industrial automation equipment requiring high-frequency operation in limited spaces.

• Compact/Short-Stroke Magnetic Cylinder Series (e.g., SDAS Series)

  • Features: Extremely short axial length, compact structure, and a flatter magnet ring design.

• Guided Magnetic Cylinder Series (e.g., TCM Series)

  • Features: Integrated guiding mechanism with high bending resistance. The built-in magnet ring is ideal for high-precision stopping and position detection.

III. How to Select the Right AirTAC Magnetic Cylinder and Magnet Components

When choosing a magnetic cylinder or matching magnetic components, consider the following key factors:

1. Verify the Model Code: Confirm whether position sensing feedback is required. If needed, ensure the model number includes "S" when placing your AirTAC order (e.g., order SCS40X100 instead of the non-magnetic standard SC40X100).

2. Match the Sensor Switch Model: Different cylinder series (such as SC, MA, SDA) have distinct body shapes and mounting grooves, requiring corresponding magnetic switches (e.g., CMSG, CS1-F, DS1-N, etc.).

3. Evaluate the Operating Environment:

   • High-Temperature Environments: If operating temperatures exceed 60°C–80°C, custom high-temperature-resistant magnet rings and heat-resistant seals are required.

   • Strong Magnetic/Electrical Interference: For applications with severe electromagnetic interference (e.g., near welding machines), select interference-resistant switches and matching accessories.

Conclusion

Selecting the right AirTAC magnetic cylinder and sensor accessories is critical to ensuring accurate position feedback and stable operation on automated production lines.
