SMC CD85N1650B (CD85N16-50-B) - Mini Air Cylinder, 16 mm Bore, 50 mm Stroke
SMC CD85N1650B Mini Air Cylinder — 16 mm bore, 50 mm stroke, rubber bumper (no air cushion), band-mounting auto switch style (B). SMC C(D)85 series ISO 6432 mini air cylinder, double acting, single rod, with built-in magnet (D) for auto switch use. Basic 'N' mounting (integral clevis) head cover. Bore 16 mm, stroke 50 mm, piston rod diameter 6 mm, rod end thread M6 x 1, port size M5 x 0.8. Rubber bumper cushioning (standard, no 'C' air-cushion suffix). Auto switch mounting style B = band mounting (a band clamps the switch around the round body); auto switches and bands are ordered separately. Proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, piston speed 50 to 1500 mm/s, ambient and fluid temperature -20 to 80 C (-10 to 60 C with built-in magnet). Allowable kinetic energy 0.09 J (rubber bumper). Not requiring lubrication. Conforms to ISO 6432 and CETOP RP52P. Weight approximately 145 g per SMC's formula (109 g basic + 7.2 g per 10 mm of stroke).

CD85N16-50-B Applications
The workhorse ISO 6432 mini cylinder for pushing, clamping, ejecting and gating light loads in compact machine frames. A 16 mm bore with 50 mm stroke covers most short-travel positioning jobs on packaging, assembly, printing and test equipment. The built-in magnet works with band-mounted auto switches so the controller can confirm extended and retracted positions, and the standard rubber bumper suits moderate cycle rates without cushion adjustment.
