SMC CJ2B1615SZ (CJ2B16-15SZ) - Mini Air Cylinder, 16mm Bore, 15mm Stroke

SMC CJ2B1615SZ Mini Air Cylinder — 16mm bore, 15mm stroke, SINGLE ACTING SPRING RETURN (S), basic (B) mounting, head cover port perpendicular to axis. This is the single-acting sibling of CJ2B16-15Z (which is double acting). CJ2 without leading D means WITHOUT built-in magnet - not auto-switch capable. SMC CJ2B16-15SZ is a CJ2-Z series mini air cylinder with a 16 mm bore and 15 mm standard stroke. The S suffix denotes single acting, spring return action - air extends the rod and an internal spring returns it, so the rod is retracted when air is removed. Mounting style B is basic (through) mounting and the head cover port is perpendicular to the axis. The CJ2 prefix (no leading D) confirms the cylinder is supplied WITHOUT a built-in magnet and therefore cannot accept auto switches; the CDJ2-Z equivalent is needed for magnetic sensing. Standard, not made-to-order.

CJ2B16-15SZ Applications

Chosen where a short 15 mm working stroke must return to a defined home position automatically if air pressure is lost, giving inherent fail-safe retraction. Typical applications include small clamps, stops, ejectors, marking heads and gate latches on assembly and packaging equipment. Air is consumed only on the extend stroke, so it suits high-cycle duties. No built-in magnet is fitted, so position confirmation must come from external limit switches rather than auto switches.
