GPS Mounting Specs [ATC unit]
Mechanical Characteristics & Mounting
The Central threaded recess accepts a metric M3 threaded bolt. The recess is approximately 4mm deep (4.32 =/- 0.08mm). The following drawing show example geometrics for mounting hardware in case you wish to design your own custom mount. The following figure shows mounting geometry for a mount formed from steel sheet metal that is 1.15mm thick. Use caution when tightening the mounting bolt. Tightening the mounting bolt can cause the mount to pull tight directly against the metal insert, not against the plastic housing, which would tent to pull the insert out of the plastic.
The GPS sensor manufactured by Agri-Tronix also has a magnet built into the unit to attach to materials that will accept a maget.
Adhesive velcro is also included with the unit to attach to fiberglass and other non magnetic surfaces.
