SMC 10-CDQSXB20-15D-A93 | Clean Room Low Speed Compact Cylinder CQSX Series 20mm Bore 15mm Stroke Double-Acting Anti-Stick-Slip With Auto-Switch

The SMC 10-CDQSXB20-15D-A93 is a clean room specification low speed compact cylinder from the CQSX series with a 20mm bore and 15mm stroke. Part number decoded: CDQSX = low speed compact cylinder, B = basic mount, 20 = bore mm, 15 = stroke mm, D = double-acting, A93 = pre-mounted auto-switch. The 20mm bore provides approximately 56% more actuation force than the 16mm bore CQSX variant while maintaining the same anti-stick-slip performance and compact square body profile.

The CQSX 20mm bore generates roughly 188N at 0.6 MPa, sufficient for medium-duty slow-approach contact operations including gentle part pressing, controlled insertion, seal compression testing, and slow-speed workpiece transfer in semiconductor and pharmaceutical clean rooms. The anti-stick-slip seal technology delivers consistent velocity even at speeds below 50mm/s, eliminating the vibration and particle generation that standard cylinders produce during low-speed operation. The pre-mounted A93 auto-switch provides end-of-stroke position detection for PLC integration without requiring on-site switch installation or adjustment. The compact square body is compatible with CQ2 mounting dimensions for straightforward retrofit.

The CDQSXB20-15D provides 56% more force than the CDQSXB16 in the same low-speed compact platform. For standard speed at 20mm bore, the CDQ2B20 costs less when anti-stick-slip capability is unnecessary. For even larger low-speed force, see CDQSXB25 or CDQSXB32. Compatible with SMC AS series speed controllers for additional velocity tuning. Clean series (10-) with fluorine grease, particle generation grade 1 compliance. RoHS compliant.
