SMC CDJ2B1045ZB (CDJ2B10-45Z-B) - Mini Air Cylinder, 10mm Bore, 45mm Stroke
SMC CDJ2B1045ZB Mini Air Cylinder — 10 mm bore, 45 mm stroke, basic (through-hole) mount, rubber bumper, built-in magnet, band-mount auto switch type. SMC CDJ2B10-45Z-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, -45 = 45 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 - 45 mm is a standard stroke; intermediate strokes producible in 1 mm increments. Mounting nut and rod end nut are supplied. Optional rod-end brackets (single/double knuckle joint) and rod end caps are available in the series.

CDJ2B10-45Z-B Applications
With a 45 mm stroke on a 10 mm bore, the CDJ2B10-45Z-B handles medium-reach light-duty moves: pusher and ejector arms, small transfer slides, gate and flap actuation, sensor or nozzle advance, and fixture clamping on packaging, electronics and laboratory automation equipment. The compact round body fits crowded panels, and the -B band-mount configuration lets D-M9 series auto switches be positioned anywhere along the tube for accurate stroke-end feedback.
