Airtac MTD Multi-position Locking Cylinder MTD6X20S
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD6X20S is a genuine MD multi-mount cylinder (single acting, pull type), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 2.2 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD6X20S
The AirTAC MD multi-mount series is a compact square-body cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side with neighbouring units to save panel space. This MTD6X20S is the single-acting, pull-type variant: compressed air retracts the rod and an internal spring returns it to the extended position. Bore 6 with a 20 mm stroke sits at the top of the single-acting stroke range, and because pull force depends on air pressure working against the return spring, confirm the exact figure from the datasheet. Cushioning is a bumper, magnetic-switch slots run around the body, and no added lubricant is needed thanks to the high guide precision.
This is a genuine AirTAC part. Within the standard MD family, the MTD prefix marks the single-acting pull type; the MK range shares the same compact body but adds a no-rotating plate, bushing and fixed rod where rod rotation must be prevented. The trailing S on this SKU means it is built with a position-detection magnet; SKUs without the S are not magnetised, since magnet is an option on this series, never a default. Medium is air filtered to 40 um, operating pressure is 0.2-1.0 MPa (28-145 psi), temperature -20 to 70 C, and we confirm 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
Bore 6 is the smallest bore in this multi-mount range, chosen for light-duty retract-to-release work rather than high thrust. For these pull-type models the force at a given pressure combines the air input with the return spring, so quote the datasheet value rather than a push-side figure. Decide between families first: MD if rod rotation is acceptable, MK if it must be prevented. Then pick the acting type - MSD (single push), MTD (single pull), or MD/MK double acting for two-way air control. Single-acting strokes run up to 20 mm, so a 20 mm stroke is the ceiling here; the short square covers caution against over-long strokes, and side-load limits should be routed to us. Magnet is option S, ports are M5x0.8 on this bore, and thread is PT as standard or G on request.
Applications
Spring-Down Gate Stopper
The spring-extended rod holds a stopper pad in the product path on a conveyor or chute; a pulse of air pulls the rod in to drop the gate and release parts. The six-direction body fixes wherever the tight transfer point needs it.
Fixture Locating Pin
A spring-extended locating pin that seats workpieces in a jig or fixture; air retracts the pin so operators can load and unload. Side-by-side mounting lets several pins sit along one fixture edge.
Indexing Detent on a Rotary Table
The extended rod engages a detent notch to hold a rotary table or dial plate between index steps; an air pulse pulls it clear during indexing. The compact square body slots into crowded machine frames.
FAQ
What does the S at the end of MTD6X20S mean?
The trailing S shows this cylinder is built with a position-detection magnet, so reed or solid-state switches can read rod position in the slots machined around the body. SKUs without the S have no magnet - magnet is an option on the MD/MK multi-mount range, never a default.
Can I use a longer stroke on this small bore?
Single-acting bores in this series run up to 20 mm, which is exactly where this model sits. The short square covers are part of the compact multi-mount design, so keep within the listed stroke range and confirm side-load limits and mounting dimensions from the datasheet - or ask us and we will pull the drawing for you.
