TempoTreadle has been installed on several Leclerc looms, new and old, including Artisat, Fanny, Nilus and most recently the Nilus II with back hinged treadles. As with many other loom makers, most of the Leclerc looms have a similar setup for how the treadles attach.
The pictures below show an older Leclerc loom with the sensor array under the treadles at the front, as well as looking at the bottom of the treadles from the back. Flat magnet brackets attach to the bottom of the treadles with velcro or double sided tape. The sensor array simply rests on the floor up against the wood at the front of the loom. The sensor array can be secured to the loom with velcro to avoid an alignment issue if the loom moves while weaving.
This is a closeup of the flat magnet bracket:
