Detailed Product Introduction: New Original SMC BMA3-020 Mounting Bracket<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The BMA3-020 is an original SMC auto-switch mounting bracket assembly, specially designed for fixing magnetic reed auto switches on pneumatic round body air cylinders. It belongs to the BMA3 band-type mounting bracket series, exclusively matched with pneumatic cylinders of 20mm bore diameter. This complete assembly contains fastening band, positioning holder, clamping bracket and installation screws as a whole set, mainly applied to install D-M9 series, D-A9 series magnetic sensors to detect piston stroke limit positions of cylinders. Widely adopted in automated assembly lines, packaging machinery, electronic production equipment, textile pneumatic equipment and general industrial pneumatic actuation systems. The band clamping structure enables flexible position adjustment along the outer surface of the cylinder barrel, which greatly facilitates on-site stroke sensing debugging without additional machining modification on cylinders.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Secure fixation of cylinder auto switches: Clamp magnetic proximity switches firmly on the outer wall of pneumatic cylinder tubes to avoid displacement caused by equipment vibration during continuous operation.<\/li>\n
  2. Stepless adjustable mounting position: The hoop band structure allows free sliding along the cylinder axial direction, users can arbitrarily set the trigger position of stroke detection according to actual working stroke requirements.<\/li>\n
  3. Complete integrated assembly: All required fastening parts are pre-equipped in one set, no need to purchase separate accessories individually, which simplifies procurement and on-site assembly procedures.<\/li>\n
  4. Compatible with mainstream SMC magnetic switches: Perfectly fit D-M9(V), D-M9W(V), D-A9(V) series reed switches, the most commonly used auto switches for miniature and medium-sized SMC cylinders.<\/li>\n
  5. Universal adaptability for multiple cylinder series: Applicable to CM2, CDM2, CDJ2, CDG1, MGC and other mainstream round cylinder series with 20mm bore size produced by SMC.<\/li>\n<\/ol>\n<\/div>\n

      5. Core Technical Features<\/h2>\n<\/div>\n
      \n
        \n
      1. High toughness transparent nylon main body: Good anti-impact, anti-aging performance, transparent design allows visual inspection of switch installation status at any time; excellent tolerance to trace lubricating oil inside compressed air pipelines.<\/li>\n
      2. Anti-slip band clamping design: The inner surface of the metal band has fine anti-slip texture, effectively preventing bracket sliding under long-term vibration working conditions.<\/li>\n
      3. Quick disassembly and adjustment: Loosen the tiny tightening screw slightly to slide the bracket freely, tighten the screw to lock the position firmly, stroke position calibration can be finished in seconds.<\/li>\n
      4. Compact miniaturized structure: Occupies minimal peripheral space of cylinders, suitable for narrow installation space inside automated equipment.<\/li>\n
      5. Stable dimensional consistency: Strict mold production ensures interchangeability between batches, installation tolerance deviation is controlled within tiny range.<\/li>\n
      6. Long service life: Wear-resistant structure design, no deformation or fracture after thousands of times of position adjustment.<\/li>\n<\/ol>\n<\/div>\n
