ARCA-IPW UL-listed, NEMA 4X, non-metallic HMI covers are a bolt-on alternative to custom HMI covers. The series has been expanded with three new sizes, namely 10 x 8 x 3.3, 14 x 12 x 3.3 and 18 x 16 x 3.3 inches. ARCA-IPW attaches to any underlying enclosure, and provides NEMA 4X protection once locked. These new sizes offer the same features as the original ARCA-IPW product family, including high impact resistance (IK 09) and an IP 67 ingress protection rating. They’re available with transparent or opaque covers and several locking options.
