The GO9 RUGGED is the sealed, weatherproof version of the GO9, built for machines that get rained on, caked in dust or pressure washed. Here is what it handles and how it gets wired in.

The GO9 RUGGED is a GO9-class tracker inside a much larger, sealed housing. It is rated IP68 and IP69K, which means it is built to keep out dust, survive immersion and stand up to high-pressure washing. The case is two-piece polycarbonate with a UL 94 V-0 flammability rating, and the device is about twice the length of a standard GO9.
Unlike the plug-in GO devices, the GO9 RUGGED connects through weather-resistant connectors and a dedicated set of harnesses. That lets it be mounted outside a cab, on a machine frame or in an engine bay, where a regular tracker would fail.
Construction and yellow iron. Excavators, loaders and dozers can report location, engine hours and fault data, which helps with theft recovery, rental billing and service scheduling.
Agriculture. Tractors and harvesters that sit out in rain and dust can be tracked with a unit made to live outside the cab.
Airport ground support. Geotab lists ground service equipment as a core use, with dedicated harnesses for battery disconnects, Kubota gas engines and Ford EDI tug engines.
Waste, mining, forestry and oilfield. Vehicles that get washed down daily or work in mud and grit need a sealed device and sealed connectors, not a plug-in tracker under the dash.

Geotab requires professional installation for the GO9 RUGGED. The harness is chosen by machine: HRN-GR09K1 is the universal 9-pin Deutsch T-harness kit, HRN-RMRCA1 adapts it for CAT machines, HRN-DC14S2 serves 14-pin CAT equipment from 2016 on, HRN-RC12T2 covers 12-pin Komatsu, and HRN-RW03K4 is the three-wire kit for machines with no diagnostic connector. HRN-RW07T1 taps J1939 directly through a 3-pin Deutsch when the diagnostic connector is not usable. The connectors are IP68 rated, and Geotab warns that removing the gray connectors reduces the weatherproofing, so leave them in place. For tight openings, connectors can be de-pinned and re-pinned while keeping the IP68 rating. Secure the harness with cable ties on both sides and keep it clear of pedals and moving linkages. If IOX modules are added, total their maximum draw and stay under the 2750 mA limit.
The GO9 RUGGED fits machines and vehicles that are exposed to water, dust or pressure washing, or that need the tracker mounted outside the cab. Heavy equipment, ag machinery and ground support fleets are its home ground.
It is the wrong pick for ordinary on-road vehicles. It is larger, costs more to install and gives up single-wire and medium-speed CAN, which Geotab notes affects some seatbelt and odometer data on certain GM, Fiat, Dodge, Ford Transit and Mazda vehicles. Pickups, vans and road trucks are better served by the GO10 or GO9B. We can supply and install the GO9 RUGGED alongside the standard devices in the same fleet.
Yes. Geotab states it can be installed outside the vehicle, and its antennas are internal, so no external antenna is needed.
Yes. A three-wire install with the HRN-RW03K4 kit, combined with intelligent ignition, tracks machines that have no usable diagnostic connector.
Geotab directs installs exposed to liquids, dust or wet cleaning to its RUGGED models, which are sealed and tested for those conditions, including the connectors.
Heavy machines rarely come to us, so we go to them: API Signal supplies the GO9 RUGGED with the harness each machine needs and installs it on site at your yard or equipment lot. Dial 803-513-1009 or fill in Get a Quote with your machine makes and models.
