Airtac MTD Multi-position Locking Cylinder MTD20X15S
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD20X15S is a genuine MD multi-mount cylinder (single acting, pull type), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 92.3 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD20X15S
The MTD20X15S is an AirTAC multi-mount cylinder: a compact square-body cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with identical units to save space. This version has a 20 mm bore with a 15 mm stroke and is single acting, pull type: air pressure retracts the rod and the internal spring returns it. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), operates from -20 to 70 C, reaches speeds of 50-500 mm/s, and is cushioned by an elastic bumper.
This is a genuine AirTAC part from the MD multi-mount family, the standard series where the rod is free to rotate; if you need the rod or plate held against rotation, choose the MK no-rotating series instead. The trailing S in the code means a magnetic piston is built in, so the switch slots around the body can be used for position sensing. Construction is typically aluminium alloy body, covers and piston with a stainless or S45C rod and NBR seals. We will confirm exact dimensions and sizing from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Choose the bore for the thrust your job needs; for this pull-type single acting variant, confirm the pull-side thrust from the datasheet, noting that the pull side delivers less force than the push side of a comparable push-type cylinder. Pick the acting type deliberately: double acting (MD), single acting push (MSD), single acting pull (MTD, this model), double rod (MDD) or adjustable stroke (MDJ). This 15 mm stroke sits within the single acting limit of 20 mm; the short cover means very long strokes are not offered, so avoid over-stroking the series. The S suffix on this SKU adds the magnet; drop it if you do not need switch sensing. Port thread is PT as standard, or G with the G suffix, both M5x0.8 on this bore. Side-load capability is not stated here; check it with us against the datasheet.
Applications
Switch-monitored conveyor stopper
Fixed through the side face beside a light conveyor lane, the magnet-equipped rod carries a stopper blade that blocks small parts on spring return; a magnetic switch in the body slot confirms the lane is clear or blocked without adding a separate sensor cylinder.
Position-verified small-parts clamp
Bolted side by side along an assembly jig, the 20 mm bore unit clamps small housings into a nest; the built-in magnet lets a slot-mounted switch signal clamp-open position on each unit, so operators know every part is released before unloading.
Jig indexing pin with sensing
Mounted under a welding or inspection jig from the bottom face, the short-stroke rod drives a locating pin into a bushed hole; the magnetic piston allows an end-of-stroke switch in the body slot to confirm full pin retraction before the next cycle.
FAQ
What does the S in MTD20X15S mean, and do I need it?
The trailing S means this cylinder is built with a magnetic piston, which lets a magnetic switch seated in the slots around the body sense rod position. The base MTD20X15 without the S has no magnet and will not trigger those switches. If your control needs an end-of-stroke or mid-stroke signal, keep the S; otherwise the non-magnet version works the same mechanically.
How many ways can I mount this cylinder, and are there stroke limits?
The square body can be fixed from 6 directions (front, back, left, right, top and bottom) and units can sit side by side to save space. Single acting versions of this series are limited to strokes up to 20 mm because of the short cover, so this 15 mm stroke is near the top of the range. Side-load figures and exact per-stroke dimensions should be confirmed from the datasheet.
