SMC CDJ2B1030ZB (CDJ2B10-30Z-B) - Mini Air Cylinder, 10mm Bore, 30mm Stroke
SMC CDJ2B1030ZB Mini Air Cylinder — 10 mm bore, 30 mm stroke, basic (through-hole) mount, rubber bumper, built-in magnet, band-mount auto switch type. SMC CDJ2B10-30Z-B is a CJ2 Series (CJ2-Z) mini air cylinder, double acting, single rod, round body. Segmentation per SMC's official CJ2-Z How to Order: C(D)J2 = series, D = built-in magnet (with auto switch), B = basic mounting style, 10 = 10 mm bore, -30 = 30 mm stroke, Z = CJ2-Z series suffix, -B = auto switch mounting type: BAND MOUNTING (alternative A = rail mounting). No cushion symbol = rubber bumper; no port-location symbol = head cover port perpendicular to the cylinder axis. Confirmed specifications (SMC catalog): double acting, single rod; fluid air; proof pressure 1 MPa; maximum operating pressure 0.7 MPa; minimum operating pressure 0.06 MPa (rubber bumper); ambient and fluid temperature -10 to 70 degC without auto switch, -10 to 60 degC with auto switch; cushion rubber bumper; lubrication not required (non-lube); piston speed 50 to 750 mm/s; stroke length tolerance +1.0/0 mm; piping port M5 x 0.8. Standard strokes for bore 10: 15, 30, 45, 60, 75, 100, 125, 150 mm - 30 mm is a standard stroke; intermediate strokes producible in 1 mm increments. Mounting styles in the series: basic (B), double-side bossed (E), double clevis (D), single foot (L), double foot (M), rod flange (F), head flange (G). Mounting nut and rod end nut are supplied.

CDJ2B10-30Z-B Applications
The CDJ2B10-30Z-B is a general-purpose short-stroke mini cylinder for light-duty automation: part stopping and escapement, small clamps, product diverters, lid and shutter actuation, and jig locating on packaging, electronics and small-parts assembly equipment. The 10 mm bore keeps thrust modest and air usage low, while the 30 mm stroke covers most short transfer moves. The -B band-mount option accepts D-M9 series auto switches for stroke-end sensing.
