The 1550Z116BK is a black textured thick-wall diecast aluminum enclosure from the Hammond 1550Z watertight series, measuring a nominal 160 x 100 mm with a 60 mm total depth. It offers a large, rib-free interior for control electronics, communications modules or instrumentation in harsh indoor and outdoor locations.
Overall dimensions per the drawing are 160.40 mm [6.31 in] long, 100.40 mm [3.95 in] wide and 60.20 mm [2.37 in] high, with inside dimensions of 150.92 mm [5.94 in] (length), 90.72 mm [3.57 in] (width) and 54.20 mm [2.13 in] (depth). The listed maximum P.C. board dimensions are 89.08 mm and 148.97 mm, and the lid height is 0.79 in (20 mm). Shipping weight is 1.48 lbs (0.67 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 black version is coated with a tough textured polyester powder finish applied inside and outside the enclosure, so the finish lasts even after machining.
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. On this size the lid screws are self-captivating: the lid holes are slightly undersized and are threaded with the first installation, so the screws stay with the lid when it is removed. 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 M4-0.7 machine screw; matching hardware is sold separately as SCGM4-50.
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.
