Koganei MR25X300-A-ZE135A2 Rodless Cylinder
The Koganei MR25X300-A-ZE135A2 is a magnet-coupled rodless pneumatic cylinder with a 25mm bore and 300mm stroke, using a neodymium rare-earth magnet coupling between the internal piston and external slider — eliminating the need for a piston rod and reducing overall mounting length. It is supplied fitted with two ZE135A solid-state sensor switches for end-of-stroke position feedback.
Technical Specifications
Cylinder
- Bore size: 25 mm
- Stroke: 300 mm
- Operation type: double acting
- Media: air
- Cushion: rubber bumper
- Lubrication: not required (non-lube)

- Operating temperature range: 0°C to 60°C
- Piston speed range: typically 100–400 mm/s for this bore class
Sensor Switches (ZE135A2)
- Sensor model: ZE135 — solid-state type, with LED indicator lamp
- Voltage: DC 10–28V
- Lead wire configuration: 2-lead wire, horizontal exit
- Lead wire length code “A”: 1000 mm
- Quantity code “2”: two sensor switches supplied (typically one per stroke end)
About the “-A” Designation
As with the 20mm-bore version, the “-A” before the sensor code is a cylinder-specific option (likely a mounting/rail or bracket variant on this Koganei rodless cylinder line). We could not confirm the exact option this represents with full certainty from public documentation — “MR” appears to be an older/legacy Koganei (possibly Humphrey-inherited) naming for what is now marketed as the MRC/MRG rodless cylinder range. If this needs to be pinned down precisely for the listing, we’d recommend checking against the original datasheet or with Koganei technical support.
Applications
Rodless cylinders of this type are used where full stroke length cannot be accommodated by a conventional rod cylinder — compact machine axes, pick-and-place transfer units, and general automation where space savings and integrated sensing (via the ZE135A switches) are required for end-of-travel detection.
