CDQSB12-15D Applications
A short-stroke compact cylinder for machine builds where panel depth is at a premium. The 12 mm bore and 15 mm stroke handle light clamping, part transfer, ejection, stopping and gate actuation on assembly, electronics and packaging lines. The standard rod end female thread lets a stud or tooling adaptor be threaded straight into the rod, keeping the overall assembly short. The built-in magnet supports flush-mounted auto switches on three or four faces so end-of-stroke position can be confirmed without adding external limit switches.
