NEMA and IP-Protected Weatherproof HMIs

All of VarTech Systems' rugged and industrial computers, monitors, and HMIs offer NEMA and IP protection, safeguarding the units from the dust and water coming from outdoor weather and processes of indoor and outdoor facilities.

In addition, we offer features to prepare units for wide temperature ranges from below-freezing to extreme heat.

NEMA and IP Ratings

NEMA ratings describe an enclosure's resistance to the ingress of water, while IP ratings describe an enclosure's resistance to the ingress of dust.

Based on your specific application, our HMIs will be prepared with the NEMA and IP protection necessary for your needs.
