SMC CDQ2B2030DZ (CDQ2B20-30DZ) - Compact Air Cylinder, 20mm Bore, 30mm Stroke
SMC CDQ2B2030DZ Compact Air Cylinder — 20mm bore, 30mm stroke, double acting, standard rod end female thread. SMC CDQ2B20-30DZ is a CQ2-Z series compact air cylinder with a 20 mm bore and a 30 mm standard stroke. It is double acting, single rod, with a through-hole (B) mounting style and a built-in magnet for auto switch position sensing. The body option is standard, giving a rod end female thread of M5 x 0.8, and no rubber bumper is fitted. The Z suffix denotes the auto switch mounting groove, machined on 2 surfaces on bores 12 to 25 mm. Ports are M5 x 0.8 and the piston rod diameter is 10 mm. Operating medium is air, with a proof pressure of 1.5 MPa, a maximum operating pressure of 1.0 MPa and a minimum operating pressure of 0.05 MPa. Piston speed range is 50 to 500 mm/s, lubrication is not required (non-lube), and the ambient and fluid temperature range is -10 to 60 C with the auto switch magnet fitted. Stroke length tolerance is +1.0 / 0 mm and allowable kinetic energy is 0.055 J. Theoretical output at 0.5 MPa is 157 N extending and 118 N retracting.

CDQ2B20-30DZ Applications
A medium-stroke standard CQ2 for clamping, pushing, stopping, lifting and short transfer moves on assembly, packaging and handling machinery where mounting depth is at a premium. The through-hole mounting style bolts the short body straight through a plate or bracket, and the built-in magnet lets auto switches drop into the machined groove for end-of-stroke confirmation without any external bracketry. The M5 x 0.8 rod end female thread accepts SMC rod end nuts, eyes and tooling adapters.
