About the Airtac SILF Front Locking Air Cylinder SILF100X350-S-TC
The S suffix is what separates SILF100X350-S-TC from its plain sibling: a built-in magnet in the piston of this 100 mm bore, double-acting end-lock cylinder. With the barrel clean of the piston, position-sensing switches mounted on the outside can read rod position along the full 350 mm stroke - useful where a controller must verify the piston is truly parked at the front cover before the next step. Mounting is TC center trunnion and the lock sits in the front (rod-end) cover per the F code.
Force is unchanged by the magnet: 3927 N push and 3682 N pull at 0.5 MPa, 5498 N and 5154 N at 0.7 MPa, through a 25 mm rod with an M20x1.5 thread. The lock holds the piston at the front cover while the lock-side port is exhausted; air on that port releases it automatically, or a hand lever releases it manually. Ports are 1/2 in PT with adjustable air cushions, pressure 0.15 to 1.0 MPa (proof 1.5 MPa), -20 to +70 C, 30 to 800 mm/s. The SILF/SILB series is discontinued, so this code ships as SAILF100X350STC and all figures describe that unit.

How to choose
Order this code only when position feedback matters: the S suffix adds the piston magnet, while the sibling SILF100X350-TC is the identical cylinder without one - blank in the ordering table means no magnet. For mounting, TC center trunnion competes with CA single clevis (rod-end pivot only) and with the basic body itself for straight-line loads. SILB100X350 codes move the lock to the rear cover, and G after the bore changes the 1/2 in ports from PT to G (BSPP).
Applications
Position-verified clamping
Switches on the barrel confirm via the piston magnet that the front lock has actually reached its holding position before the PLC releases the part.
Weld and assembly fixtures
Trunnion mounting follows the fixture arc while sensor feedback on the 350 mm stroke catches incomplete retraction between cycles.
Manually released safety positions
After a hand-lever release, position switches show operators when the piston is truly held at the front cover before service begins.
FAQ

Why does this order code ship as SAILF100X350STC?
AirTAC has discontinued the SILF/SILB end-lock series and replaced it with SAILF/SAILB. Every SILF code on this page, including SILF100X350-S-TC, is supplied as the current SAILF code with the same characters after the prefix - here SAILF100X350STC. The specifications you receive are those of the SAIL unit; no hyphen is used in the replacement code.
