Airtac MTK Multi-position Locking Cylinder MTK6X15S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK6X15S is a genuine MK 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. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MTK Multi-position Locking Cylinder MTK6X15S
The MTK6X15S is a compact MK-series multi-mount cylinder from AirTAC with a square body that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side to save space. Magnetic-switch slots run around the body for position-sensing use. This 6mm bore, 15mm stroke version is single acting of the pull type: compressed air retracts the rod, with a bumper providing the cushion. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) and from -20 to 70 C (0 to 150 C only with the optional high-temperature seal material).
This is a genuine AirTAC part in the MK family, so a no-rotating plate, brass bushing and fixed rod stop the rod from turning - unlike the standard MD series. The trailing S in the SKU means this unit is built with a magnet for switch detection; the non-S MTK6X15 is the equivalent without. Confirm exact dimensions, pull-side force figures and sensor selection from the datasheet - we can provide it 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
At 6mm bore this is the smallest MK size, suited to light holding and return tasks; the pull-type single acting design retracts the rod under air pressure and extends by return, so confirm the pull-side force for this bore from the datasheet before sizing. Operating pressure is 0.2-1.0 MPa (28-145 psi) for all single-acting bores.
Choose MK over MD when the rod must not rotate; MD allows rotation. Stroke here is 15mm within the single-acting range of up to 20mm. The trailing S gives you the magnet option for position switches - choose the non-S code if you do not need sensing. Thread is PT by default with G available. Avoid over-long strokes on this short-cover body; route side-load questions to us.
Applications
Gate pin with end detection
Air pulls the stopper pin down to release cartons on a light-duty conveyor gate, while the built-in magnet lets a switch confirm the retracted position.
Jig clamp release sensing
In a compact machining fixture, air retracts the clamp plunger and the magnet confirms to the PLC that the part is free before the next indexing step.
Lateral eject confirmation
Mounted from the side face, the cylinder pulls a small ejector back between pick cycles; switch slots around the body give a confirmed home position.
FAQ
What does the S in MTK6X15S mean, and is the magnet standard?
The trailing S means this cylinder is built with a magnet in the piston, so reed or Hall-effect switches can detect rod position in the slots around the body. The magnet is an option on the MD/MK series, not a standard feature - the equivalent code without S (MTK6X15) has no magnet and cannot be sensed.
Why choose a pull-type single-acting MK cylinder, and what limits the stroke?
Pull type (MTK) means air retracts the rod on the working stroke and it returns by the opposite means, which suits release, unclamp and eject jobs; the MK no-rotating plate and fixed rod keep the rod from turning, unlike the standard MD series. Single-acting strokes run up to 20mm on this series, and this short-cover body should not be pushed into over-long strokes - confirm dimensions and side-load from the datasheet, which we provide on request.
