All our PCs use Bulgin IP68 rated connectors. They are designed for use in harsh environments and are very rugged and able to facilitate reliable and secure power, signal and data connections. We also supply a range of cables to compliment the connectors. To further enhance water resistance, each one of our connectors is supplied with a sealing cap. Our stainless steel power buttons are vandal proof and IP rated. We also use Wiska pressure regulators on our connection plates to ensure equal atmospheric pressure within the cabinet.
