SMC CDQ2B2010SZ (CDQ2B20-10SZ) - Compact Air Cylinder, 20mm Bore, 10mm Stroke
SMC CDQ2B2010SZ Compact Air Cylinder — 20mm bore, 10mm stroke, single acting spring return. SMC CDQ2B20-10SZ is a CQ2-Z series compact air cylinder with a 20 mm bore and a 10 mm standard stroke. It is single acting, spring return, single rod, with a through-hole (B) mounting style and a built-in magnet for auto switch position sensing. Air extends the rod and the internal spring returns it, so the cylinder fails to the retracted position on loss of air. The body option is standard, giving a rod end female thread of M5 x 0.8. 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 and a maximum operating pressure of 1.0 MPa. Being single acting, the minimum operating pressure is 0.18 MPa at 20 mm bore, substantially higher than the 0.05 MPa of the double acting version, because the air must overcome the return spring. Spring reaction force at the 10 mm stroke is 15 N compressed and 5.9 N as set in the cylinder. 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 142 N extending.

CDQ2B20-10SZ Applications
A spring return compact cylinder is the right choice where the actuator must retract automatically if air pressure is lost, giving a safe fail-retracted state on clamps, gates, stops, pin locators and ejectors. Only one air line is needed, which simplifies plumbing and valve count. The through-hole mount and built-in magnet allow flush bolting and auto switch position sensing. Note that the higher 0.18 MPa minimum operating pressure must be supplied to overcome the return spring.
