SMC CDQ2B40TF40DZ (CDQ2B40TF-40DZ) - Compact Air Cylinder, 40 mm Bore, 40 mm Stroke
SMC CDQ2B40TF40DZ Compact Air Cylinder — 40 mm bore, 40 mm stroke, G1/8 (TF) port thread, standard body with rod end female thread and no rubber bumper. SMC CDQ2B40TF-40DZ is a CQ2 series compact air cylinder with a 40 mm bore and 40 mm stroke. Double acting, single rod, with a built-in magnet (D) for auto switch position sensing on 4 surfaces via the Z mounting groove. Through-hole (B) body mounting. Port thread type TF = G (BSPP), giving G1/8 ports at this bore. Standard body option: rod end female thread, without rubber bumper. Fluid: air. Proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa. Piston speed 50 to 500 mm/s. Non-lube operation. Ambient and fluid temperature -10 to 60 C with auto switch magnet. Allowable kinetic energy 0.26 J.

CDQ2B40TF-40DZ Applications
Chosen where a moderate stroke must fit a shallow mounting depth: transfer pushers, lift-and-locate stations, tool changers, and packaging flap folders. With a 40 mm bore the cylinder produces strong thrust at typical 0.5 MPa shop pressure, and the through-hole body bolts directly to a plate without brackets. The built-in magnet supports D-M9 series auto switches on any of four faces, so sensor routing can follow the machine layout rather than dictating it.
