Airtac MTD Multi-position Locking Cylinder MTD16X20S
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD16X20S is a genuine MD multi-mount cylinder (single acting, pull type), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 60.5 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD16X20S
The MTD16X20S is an AirTAC multi-mount cylinder: a compact square-body actuator that fixes from six directions - front, back, left, right, top and bottom - so several units can be mounted side by side to save space. Magnetic-switch slots run around the body. This unit is the MTD variant, single acting, pull type: applied air pulls the rod in and the spring extends it when air is removed, giving a natural fail-out action. The trailing S in the code means this SKU carries a magnet for position sensing. The bore 16 x 20 mm stroke suits short-reach pull-in work; it runs on filtered air (40 um) at 0.2-1.0 MPa (28-145 psi) at 50-500 mm/s with a bumper for cushioning. Theoretical pull force for bore 16 is listed in the datasheet; the push side of a single-acting cylinder always gives more force than the pull side.
This is a genuine AirTAC part from the standard MD family; the MK family is the no-rotating version with an anti-rotation plate if rod rotation must be prevented. This SKU is shown WITH a magnet (the S) and PT thread by default, with G selectable. We confirm dimensions, weights and sizing details 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
Select the bore for thrust: bore 16 delivers its rated single-acting pull force at 0.5 MPa per the datasheet, and since the push side always exceeds the pull side on single-acting cylinders, choose pull type (MTD/MTK) where spring-out, air-in action is wanted. Decide MD (rod rotation allowed) versus MK (no-rotating) first. Acting options are double, single push, single pull, double rod or adjustable stroke. Single-acting strokes stop at 20 mm, so this 20 mm stroke is already the maximum - short covers will not allow an over-long stroke, so check any non-standard length with us. The magnet is optional and ordered via the trailing S, which this SKU has; port thread is PT by default with G available. Side-load figures and exact dimensions come from the datasheet - just ask.
Applications
Spring-out press-lite seat check on a small fixture
The spring keeps the plunger out so the operator always sees go/no-go position, and air pulls it back to clear the part. The magnet drives a switch to confirm retraction, and six-way fixing lets the body sit flush inside the fixture plate.
Sensor-verified divert stopper between conveyor lanes
Normally extended by its spring, the rod blocks small packages at a junction; air pulls it in to divert flow. The magnet allows a retracted-position signal for PLC interlocking, and side-by-side mounting stacks multiple stoppers on one rail.
Indexing pin with position feedback on a dial table
Spring extends the pin into the index plate; air retracts it for rotation. The magnet confirms pin-in/pin-out to the controller, the compact square body fits the shallow table skirt, and the 20 mm stroke matches typical index-plate pocket depth.
FAQ
What does the S at the end of MTD16X20S mean?
The trailing S means this cylinder is supplied WITH a built-in magnet, so magnetic switches can be clipped into the slots around the body for position sensing. The same cylinder without an S in the code is supplied without a magnet - the magnet is an option on the MD/MK range, not a standard feature, so order the S version if you need switch feedback. Thread is PT on this SKU; G is selectable at order time.
Is 20 mm really the longest stroke for this single-acting pull cylinder?
Yes. Single-acting MTD variants are offered only up to 20 mm stroke, so the 20 mm on this SKU is at the maximum - the short covers do not permit an over-long stroke. If your job needs more travel, step up to a double-acting MD or MK unit, or an MDJ/MKJ model that adds a 10/20/30 mm adjustable range. Exact body dimensions for the chosen stroke are in the datasheet; we can confirm them for you.
