Can your PnP place this component?

Not sure how it correctly called - is it some sort of a grip nozzle required?

Manufactures often sell this kind of connector with an additional thingy (e.g. an clipped on plastic part or a piece of attached kapton film) to ease PnP. This thing has to be replaced after reflow. The ones as shown look difficult for the usual vacuum based PnP heads.

^^ what he said. This is why I advise not to use an SM connector without good reason. If you are working in volume or need to, fine, otherwise SM connectors can need tooling (bye bye labour saving) or available stock in a very specific part number that adds a pick pad to the connector, or placing with tweezers - maybe not as straight as you'd like.  Here is a datasheet for a similar terminal https://www.toby.co.uk/uploads/publications/263.pdf where you can see the last letter denotes a variant with pick pad and its an option, Samtec are quite nice, datasheets are readable and part number easy to derive... unlike Molex.

I can only assume some machines do use some form of gripper or the versions without pick pads would not exist, however plenty of machines don't have that option. Its not just male pin headers that have this problem, pin sockets can have the same issue as the holes dissipate too much of the vacuum,but some machines might not care or let you turn off the vacuum check for specific parts.

That would be a challenge for me.

What about U.FL / IPX connectors? My machine manages most of the time, but it's not ideal.

Dealt with a similar connector before, we were lucky enough to have a nozzle that just fitted between the pins. But as others have said usually connectors like these come with a little plastic cap or a piece of kapton tape that you pick them up with

Ehhh, seems like they can process a custom-made order, not in a hassle free way as Samtec, but still they can...

Alternative, gripper nozzles might cost a fortune  :o
