Koganei MRGH20X200 Magnet Rodless Cylinder 20mm Bore 200mm Stroke w/ Sensors

Koganei MRGH20X200 Magnet Rodless Cylinder 20mm Bore 200mm Stroke w/ Sensors

The Koganei MRGH20X200 is a magnet-type rodless pneumatic cylinder actuator with a 20mm bore and 200mm stroke. Rodless cylinders use a magnetically coupled external carriage instead of a protruding piston rod, allowing the carriage to travel the full stroke length without the rod overhead — making them a compact choice for linear positioning tasks in automated machinery. This unit comes mounted with an aluminum work tray and includes position-sensing hardware.

Applications

Magnet-type rodless cylinders like the Koganei MRGH series are standard linear motion components in semiconductor handling, electronics assembly, laboratory automation, and general factory automation. The rodless design keeps the actuator's installed footprint shorter than the stroke length — useful where a conventional rod cylinder's extension would intrude into adjacent equipment. The ZG530A reed-switch sensors detect the carriage's end-of-travel positions, feeding signals to a PLC or motion controller for sequencing and interlock. The Omron EE-SPY402 photomicrosensor provides additional position or object-detection capability — commonly used in wafer or substrate handling tray applications where optical sensing of a part's presence is needed. This combination of actuator, position sensors, and a precision tray is typical of pick-and-place or indexing sub-systems in semiconductor fab and PCB assembly equipment from the 1990s–2000s era.
