CDQSB20-10D Applications
A short-stroke 20 mm bore actuator for compact clamping, pressing, stopping and part ejection on assembly, packaging and small material handling machines. The larger bore raises thrust over the 16 mm size while the square CQS body keeps the installation flat. Auto switches can be fitted on four sides thanks to the built-in magnet, giving flexible position feedback routing. The female rod end thread accepts tooling, pads or brackets directly for simple pusher and clamp designs.
