Pagination with javascript:getNextPage(different link)

Hello, Guys
Url: https://www.molex.com/molex/search/deepSearch?pQuery=category%3A%22PCB%2BReceptacles%22%40productname%3AMini-Fit*

Each page shows 20 items and has a special pagination link, each secondary page link is generated based on the previous page with the offset=n*20 parameter

I have tried several posibilities according to the pagination and elementclick tutorial video, but with no luck.

Can you guys confirm whether this kind of pagination is scrapable or can fine tune my sitemap below?
Thanks with sweet X'mas wishes.
