Hammond IP68 1550ZF enclosures

Hammond has introduced the IP68 1550ZF range: flanged versions of all 18 sizes in its heavy-duty 1550Z die-cast aluminium enclosure family. The full-size flange is spot-welded to the base to provide a strong, smooth mounting plate for use when the units are secured to a surface.

The 18 sizes range from 50 x 45 x 30 mm to 223 x 147 x 83 mm, with the lid’s thickness ranging from 5–33 mm in depth depending on the size. The tongue and groove design and a pre-formed one-piece silicone rubber gasket provide IP68 environmental protection, making the enclosures suitable for installation in environments where dust and water will be present.

The enclosures are UL- and cUL-listed and have been independently tested to IP66, IP67 and IP68. They are also rated to NEMA Type 4, 4X, 12 and 13. All sizes except the smallest have an impact rating of IK08, defined in IEC 62262 as the equivalent to the impact of a 1.7 kg mass dropped from 300 mm above the impacted surface.

Depending on the size, the lid is secured to the base with either two, four or six stainless steel Philips machine screws located outside the gasketed area, giving repeated access without degrading the environmental protection. The enclosures are available in a natural finish or with a tough polyester black powder finish to both the outside and inside. In the painted versions, clear areas are provided around the grounding points.
