IP30 rated rugged housing, means that the brainboxes serial over network device can operate in industrial environments

Rugged Enclosure

IP-30 rated rugged case protects the device in any environment from industrial to office based.

IP (Ingress Protection Rating*) Code 30 specifies that objects greater than 2.5mm in diameter cannot penetrate the case, this means that the case provides a safety barrier from objects (such as tools and wires) interfering with the internal circuitry.

* Also Known As International Protection Rating
