TG-BT5-OUT: the heavy-duty tag for industrial challenges. This version of our BLE tags comes completely sealed, cast in industrial-grade molds to give it a solid IP69k ingress protection rating. In other words, this tag is dust-tight – nothing gets in, and it is fully protected against close-range high-pressure, high-temperature spray downs. Perfect for industrial telemetry systems or to track all kinds of heavy equipment and materials at a construction site. TG-BT5-OUT features an improved 550 mAH battery that will last around five years (with a sending interval of 1s). It is suitable for strapping to all kinds of surfaces, and it can handle a temperature range of -20°C to 85°C.
