The SMC 25A-CDQ2A40-20DZ-M9NVL is a secondary battery compatible compact cylinder with 40mm bore and ultra-short 20mm stroke, delivering high force through minimal travel. Part number decoded: CDQ2 = CQ2 double acting, A = A-type, 40 = 40mm bore, 20 = 20mm stroke, D = standard option, Z = auto-switch groove, M9NVL = pre-mounted NPN auto-switch with V voltage rating and L lead wire.
The 40mm bore at only 20mm stroke creates one of the highest force-to-travel ratios in the CQ2 range: approximately 75N concentrated into just 20mm of travel. This configuration excels where decisive contact force must be applied over a short distance. The M9NVL switch provides NPN output with voltage-specified sensing for clean signal quality in electrically noisy battery production environments.
Ideal for electrode tab spot-welding fixture clamps where tabs must be pressed firmly against the current collector before the welder fires, cell OCV (open circuit voltage) test probe contact actuation, pouch cell edge-crimp dies, and prismatic cell vent-valve press-fit tooling. Choose the 40mm bore 20mm stroke over the 32mm bore 25mm stroke when clamp force above 50N is essential and travel below 25mm is acceptable. For longer stroke at this force, the CDQ2A40-30DMZ provides 30mm. For even shorter travel, consider the CJP2 pin cylinder series at 5mm stroke. RoHS compliant.
