The Liberia international, 21, is yet to make a senior appearance for the Premier League club, but has been a regular for the under-23 side.
Sangare spent time in the north west with the Stanley development squad earlier in his career but was unable to gain a work permit to sign at the time.
He joins fellow Newcastle loanee Tom Allan at the Wham Stadium.
"I spent around eight months here when I first came over from Liberia," said Sangare.
"I couldn't speak a lot of English and going to Accrington and Rossendale College helped me. I know Ross Sykes and Reagan Ogle from that time and obviously it helps with Tom Allan being here on loan from Newcastle as well."
