CDQSB20-15DM Applications

Specify this variant when the piston rod must screw into a knuckle joint, clevis, floating joint or threaded link rather than take a bolted pad. Typical duties are compact clamping, pressing, stopping, ejecting and short-travel transfer on assembly and packaging machinery where the square CQS body saves mounting space. The built-in magnet lets auto switches be mounted on four sides for reliable stroke-end sensing, and the rod end nut and knuckle accessories are standard SMC items.
