Cap In Chute Sensors specification should start with the real closure.
Cap-in-chute sensors help the feeder run only when the capper needs caps. They can reduce chute pressure, lower the risk of jams and give better fault information when the cap queue becomes too short or too long.
For a better buying decision, the useful comparison is not only hopper size or headline speed. It is how the feeder behaves with your closure, how the capper receives the cap and how easy the line is to run after changeover.
The safest specification route is to start with real closures, target output, line photos and the exact point where the cap must be presented. That avoids choosing a feeder on a generic speed figure that does not match the cap or capper.
