Koganei part number MR20X200-A-ZE135B2 is a magnet-type rodless pneumatic cylinder, bore 20mm, stroke 200mm, fitted with two ZE135B solid-state sensor switches.
Koganei MR20X200-A-ZE135B2 Rodless Cylinder
The Koganei MR20X200-A-ZE135B2 is a magnet-coupled rodless pneumatic cylinder with a 20mm bore and 200mm 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 ZE135B solid-state sensor switches for end-of-stroke position feedback.
Technical Specifications
Cylinder
- Bore size: 20 mm
- Stroke: 200 mm
- Operation type: double acting

- Operating temperature range: 0°C to 60°C
- Piston speed range: typically 100–400 mm/s for this bore class
Sensor Switches (ZE135B2)
- Sensor model: ZE135 — solid-state type, with LED indicator lamp
- Voltage: DC 10–28V

- Lead wire length code “B”: 3000 mm
- Quantity code “2”: two sensor switches supplied (typically one per stroke end)
About the “-A” Designation
The “-A” appearing before the sensor code in this part number is a cylinder-specific option (commonly a mounting/rail or bracket variant on Koganei’s rodless cylinder lines). We could not confirm the exact option this represents from public documentation with full certainty — if you need this pinned down precisely for the listing, we’d recommend confirming against the original Koganei/Humphrey datasheet or with Koganei technical support, since “MR” appears to be an older/legacy naming for what Koganei now markets under the MRC/MRG rodless cylinder range.
Applications
Rodless cylinders of this type are used where full stroke lengthcannot 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 ZE135B switches) are required for end-of-travel detection.
