The differences between 6600-068 (formerly 6600-129) and the 6600-144 is the length of the cable. They are the same sensor. 6600-144 is 2' 8" long and has the curled finger connectors (see pictures above or related products below for what the connectors look like). 6600-068 (formerly 6600-129) is 7' 5" long and has the curled finger connectors. The original 6600-140 had the white plastic connector with the curled finger connectors in it to plug into the board (No longer available). The 6600-144 is the part available. You have to remove the old connector from the white plastic housing and reuse the white plastic housing.

If you are not sure which to choose, we recommend ordering 6600-068 because it is the longest cable.
