CDQSB20-40D Applications

With a 40 mm stroke in a compact square body, this CQS cylinder handles slightly longer transfer, lifting and pusher movements while still fitting tight machine frames. The built-in magnet supports flush-mounted auto switches on multiple faces for reliable position confirmation. Typical uses include diverting products on conveyors, raising locating pins, opening chutes and actuating light guards in packaging, electronics assembly and small-parts handling equipment operating on standard shop air up to 1.0 MPa.
