CDQSB12-30D Applications
A 12 mm bore CQS cylinder with a longer 30 mm stroke for jobs that need more rod travel while keeping the shallow square footprint. Suits pushers, part transfer, clamping, ejection and stopper duties on assembly, electronics and packaging machines where a round tie-rod cylinder would not fit. The standard rod end female thread accepts a threaded stud or tooling adaptor directly. The built-in magnet supports flush auto switch mounting on three or four faces, giving end-of-stroke confirmation without external limit switches or brackets.
