The AirTAC Airtac SC32 Standard Cylinder SC32X685S is a genuine double-acting standard air cylinder with a Ø32mm bore and 685mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X685S is a double-acting AirTAC SC tie-rod cylinder with a 32 mm bore and a 685 mm stroke, pre-equipped with a built-in magnet for direct mounting of CMSG, DMSG, or EMSG sensors. This configuration delivers a push force of 402 N at 0.5 MPa and reaches 724 N at the maximum operating pressure of 0.9 MPa, making it a compact workhorse for light automation tasks.
Its 12 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration at end-of-stroke, while the PT1/8 port and M10x1.25 rod thread ensure standard pneumatic connections. The body length A is 140 mm, keeping the total extended length compact for integration into space-constrained fixtures.

The 402 N push force at 0.5 MPa efficiently shifts small components between conveyor lanes, with the 685 mm stroke covering wide transfer gaps in packaging lines.
The built-in magnet and CMSG sensors enable precise mid-stroke position feedback for sorting gates, ensuring accurate part diversion at multiple points along the 685 mm travel.
Delivers smooth, adjustable-speed linear motion for test-rig samplers, where the 21 mm cushion protects delicate glassware at the end of the 685 mm stroke.
For applications requiring slightly more force, stepping up to the 40 mm bore SC40 series provides 628 N of push at 0.5 MPa. With a 685 mm stroke, the slender 12 mm rod is susceptible to bending under side loads; always guide the load externally or use a rod-alignment coupler to prevent bearing wear and rod buckling. When replacing an existing cylinder, match five points: 32 mm bore, 685 mm stroke, PT1/8 port thread, the basic mounting configuration, and the -S magnet option for sensor compatibility.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N.
Yes. The -S suffix in SC32X685S denotes a built-in magnet, allowing AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless position sensing.
