The 1550Z111 is a natural (unpainted) thick-wall diecast aluminum enclosure from the Hammond 1550Z watertight series with a nominal 115 x 65 mm footprint and a comparatively deep 55 mm total depth. The narrow, tall body is useful for electronics builders who need vertical room for connectors, components or cable entry on a small plan area.
Overall dimensions per the drawing are 115.40 mm [4.54 in] long, 65.40 mm [2.57 in] wide and 55.40 mm [2.18 in] high, with inside dimensions of 107.37 mm [4.23 in] (length), 57.37 mm [2.26 in] (width) and 49.70 mm [1.96 in] (depth). The listed maximum P.C. board dimensions are 56.7 mm and 106.7 mm, and the lid height is 0.20 in (5 mm). Shipping weight is 0.67 lbs (0.30 kg).
Box and lid are made from diecast aluminum alloy that is tough yet easy to machine, and the walls have no internal ribs, so connectors fit without interference or extra milling. This unpainted version is vibra finished for a smooth natural aluminum surface with no sharp edges, and the alloy is easy to machine for custom openings.
The purchased assembly includes the box, lid, silicone gasket and 4 stainless steel Phillips head cover screws, which sit outside the gasket protection area so no o-rings are needed. Recommended cover screw torque is 5-7.5 lbf.in (50-75 cN.m). For wall mounting, the box uses blind thru-box holes located outside the gasket ring, so access to them does not compromise ingress protection. An internal ground point accepts an #6 self tapping screw; matching hardware is sold separately as SCG060-50.
The 1550Z series is cUL and UL listed (file #E71073) and independently tested to IP66, IP67, IP68 and NEMA Type 4, 4X, 12 and 13; this size is rated IK08 per IEC62262. It is RoHS and REACH compliant; customers should test suitability for their specific application.
