REC, Accessory, Mounting Brackets
The transportation of delicate items often requires greater control of cylinder acceleration and deceleration than is afforded by traditional air cushions. For this reason, SMC has developed the REC sine cylinder. The term "sine cylinder" is derived from the shape of the velocity curve at both ends of stroke. This control is achieved with the addition of two grooves on each cushion spear which results in a more gradual initial acceleration or deceleration and smooth transition to or from full speed operation. To accomplish this type of motion with a traditional cylinder typically requires extensive external flow control. REC is a repairable basic cylinder.

∗
Solid state auto switches marked with “쎻” are produced upon receipt of order.
∗ D-A9쏔V/M9쏔V/M9쏔WV/M9쏔A(V)L types cannot be mounted.
∗ Do not indicate suffix “N” for no lead wire on D-A3쏔/A44/G39/K39 models.
∗ Since there are other applicable auto switches than listed, refer to page 1040 for details.
∗ For details about auto switches with pre-wired connector, refer to pages 1784 and 1785.
∗ D-A9쏔/M9쏔/M9쏔W auto switches are shipped together (not assembled). (Only auto switch mounting brackets are assembled before shipped.)
