SMC 10-CDQ2B12-20DCZ | Clean Room Compact Cylinder CQ2 Series 12mm Bore 20mm Stroke Double-Acting Both Ends Tapped Auto-Switch Ready

The SMC 10-CDQ2B12-20DCZ is a clean room specification compact cylinder from the CQ2 series with a 12mm bore and 20mm stroke. Part number decoded: CDQ2 = compact cylinder with air cushion capability, B = basic mount, 12 = bore diameter in mm, 20 = stroke in mm, D = double-acting, C = both ends tapped for versatile mounting, Z = auto-switch groove. The 10- prefix designates clean series manufacturing with fluorine grease, controlled assembly, and anti-static double packaging for particle generation grade 1 environments.

This compact square-body cylinder operates at 0.05 to 1.0 MPa and generates approximately 68N of force at 0.6 MPa. The low-profile design significantly reduces mounting height compared to round-body cylinders at the same bore, making it ideal for tight clean room equipment enclosures. Both-ends-tapped construction allows mounting from either the rod or cap end, or through-bolting for maximum rigidity. The magnetic piston enables external position sensing via SMC D-series auto switches without cylinder disassembly.

The compact 12mm bore is designed for micro-actuation in semiconductor wafer handling, electronics assembly, and pharmaceutical clean rooms where minimal footprint is critical. The square body profile reduces mounting height versus round cylinders in confined spaces, and the both-ends-tapped (C) configuration provides maximum mounting flexibility for custom tooling. Double-acting operation delivers powered extend and retract cycles, and the clean series (10-) fluorine grease with anti-static packaging ensures Particle Grade 1 compliance.

For longer strokes in the same bore, consider the CDQ2B12-30DCZ (30mm) or CDQ2B12-50DCZ (50mm). For larger force in a compact envelope, the CDQ2B16 (16mm bore) and CDQ2B20 (20mm bore) maintain the same square body profile with increased output. Part of SMC's CQ2 compact cylinder family offering bores from 12mm to 100mm with strokes up to 300mm. Compatible with SMC D-series auto switches, AS series speed controllers, and KQ2 one-touch fittings for complete clean room pneumatic system integration. RoHS compliant.
