Can you add some more to comment on ? If you asking for a type, I'm no help!

If this is a personal door put a magnet contact NC and when broken air start's.

If this is required by Health req's. I check with them.

If you asking about the previous type of unit or for a rollup door look HERE.

Make sure the door is hollow if in masonry or concrete walls if you plan to use an insert.

I'm not that familiar with quality door contacts for a metal door frame.

Looking for a good door contact 24v. Is a roller ball jab contact quality?

I saw a push in contact that fits like a push in plastic ko seal. But I can't find the model number for 24v.
Feedback is appreciated
