Hammond 1590Z137 200x80x60mm Natural Diecast Aluminum Enclosure

The 1590Z137 is a thick-wall, watertight diecast aluminum enclosure from the 1590Z Type 4X/ 6P series, left in its natural, unfinished diecast aluminum. A long, narrow 200 mm format for elongated electronics that need a sealed metal housing, it suits OEM engineers, electricians and integrators.

It is 7.87 in (200 mm) long, 3.15 in (80 mm) wide and 2.36 in (60 mm) in total depth, with a 0.79 in (20 mm) lid. Inside, the drawing shows 191.11 mm [7.52 in] length, 70.78 mm [2.79 in] width and 52.50 mm [2.07 in] depth, with an average wall thickness of 4.00 mm [.16 in]. Shipping weight is 1.54 lbs (0.70 kg).

Construction is two-piece tongue and groove with a replaceable one-piece silicone rubber gasket, rated -40C to +150C (-40F to 302F), that is supplied loose inside the enclosure rather than pre-installed. Four recessed stainless steel M4 - 0.7 machine screws hold the lid at a recommended torque of 8.9-10.6 lbf.in (100-120 cN.m). The purchased assembly includes the box, lid, silicone gasket, 4 cover screws and 3 ground screws with washers. The lid screws are self-captivating and create threads on first installation, and the design is intended for repetitive opening and closing.

For installation, blind through-holes located outside the gasket protection allow easy wall mounting. An internal mounting shelf accepts the optional 1590Z137PL steel inner panel. Spares are SC574-30 lid screws (30 pack, M4 - 0.7 x 30mm), SCGM4-50 copper ground hardware (M4 - 0.7 x 6mm / M4 washer) and the 1590Z137G gasket two-pack.

The series is cUL and UL listed (file E65324), independently tested to IP66, IP67 and IP68 and to NEMA Type 4, 4X, 6, 6P, 12 and 13, and carries an IK08 impact rating per IEC62262. Customers should confirm suitability for their application by their own testing. This natural version is unpainted; the same size is also offered in textured black and smooth gray RAL 7001.
