Queclink GV651CAU

Queclink GV651CAU — LTE Cat 1 bis Rugged Waterproof Tracker for Equipment and Trailer Tracking

The Queclink GV651CAU is a rugged LTE Cat 1 bis tracker specifically engineered for heavy-duty equipment and trailer tracking applications. Its IP67/IP69K dual-rated waterproof construction ensures reliability in the harshest outdoor environments, withstanding both temporary immersion and high-pressure wash-down — a critical requirement for equipment operated on construction sites, in agriculture and in tanker fleets.

The GV651CAU is powered by a 5,800mAh Li-ion battery pack that provides up to 4 months of operation without external power, maintaining continuous visibility of trailers and equipment even during long disconnected periods. Dual-band L1/L5 GNSS with AGPS support delivers enhanced positioning accuracy, including inside enclosed trailers where an optional external antenna can be installed. Multiple I/O interfaces — including 5 configurable digital I/Os, 2 analog inputs and a 1-Wire port — support a comprehensive range of pre-integrated accessories for driver identification, temperature monitoring and engine management.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV651CAU directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.
