SMC CDNAFN100-250-D-Y7NWL Pneumatic Cylinder 100mm Bore 250mm Stroke Auto Switch

SMC CDNAFN100-250-D-Y7NWL Pneumatic Cylinder 100mm Bore 250mm Stroke Auto Switch

The SMC CDNAFN100-250-D-Y7NWL is a front-flange-mounted pneumatic cylinder from SMC's CNA series, featuring a 100 mm bore and 250 mm stroke. It includes integrated auto-switching capability via built-in reed/solid-state switch wiring and a front flange (F) mounting style for rigid machine-frame attachment. The full model suffix CDNAFN100-250-D-Y7NWL encodes the bore, stroke, double-acting configuration, and switch/wiring option, making it a purpose-engineered actuator for demanding industrial automation tasks.

Applications

SMC's CNA/CDNA series are heavy-duty double-acting pneumatic cylinders used throughout industrial automation for tasks requiring high force output and long stroke travel. The front flange mount is common in fixed machine-frame installations where the cylinder body must be rigidly secured to a structural plate — typical in pick-and-place systems, clamping fixtures, press-and-lift mechanisms, and conveyance handling equipment. This particular unit was installed in a solar module manufacturing machine designed to pick up and position flexible solar panels, a precision application that places a premium on smooth, repeatable actuation and reliable auto-switch position feedback. The 100 mm bore produces substantial output force at standard shop-air pressures (approximately 7,850 N at 1.0 MPa), making it well suited for handling relatively large or heavy panels and workpieces. The included SMC JAF100-26-150 floating joint compensates for minor rod-to-load misalignment and is a standard accessory used to protect the cylinder rod from side loading in these kinds of guided linear motion applications. SMC CNA-series cylinders are manufactured in Japan to ISO 15552 compatible dimensions and remain current production components widely used in semiconductor, solar, automotive, and general factory automation environments.
