Hammond 1457J1201BK 120x84mm IP65 Black Watertight Enclosure

The 1457J1201BK is a watertight extruded aluminum enclosure from the Hammond 1457 series, designed to meet IP65. It is the non-flanged version, with flat end panels and no mounting flanges. It houses PC boards or serves for equipment interfacing, for OEM designers and integrators needing a small sealed metal case.

The enclosure measures 4.73 in x 3.3 in x 1.12 in (120 mm x 84 mm x 28 mm). In the series table the extrusion is 120.00 mm long, 84.00 mm wide and 28.50 mm high, and the maximum PCB size is listed as 120.00 x 80.00 mm; the part page lists the maximum P.C. board as 119 mm x 79 mm, and the drawing notes it fits a 120mm (4.724") X 80mm (3.149") PCB. Boards slide horizontally into internal slots. The drawing gives an extrusion length of 120.00 ±0.50 mm [4.724 ±0.020 in] and an overall assembly length of 131.15 mm [5.163 in]. Drawing width is 86.96 mm [3.424 in] and height 28.50 mm [1.122 in].

The body is one piece of extruded aluminum with a minimum thickness of 0.06" (1.5 mm) and a black powder coat finish. The body includes a recessed area 0.75 mm (0.030") deep for labels or a membrane keypad. The two end panels are diecast aluminum painted in black satin powder paint. They are easy to machine and carry full-perimeter self-adhesive gaskets.

Included in the box: the body, two diecast end panels, two closed-cell polyethylene foam end plate gaskets, and stainless steel assembly hardware with a rubber o-ring and adhesive rubber feet. The thread-forming screws are black zinc plated to ASTM B633-13, Type II (96 hour salt spray test), SC3 severe rating (12 micron coating). Recommended screw torque is 5 lbf/in, and replacement screws come in packs of 100 as 1457MS100.

Replacement end panel kits for 1457J enclosures are 1457JWP (2-pack) and 1457JWP-10 (10-pack). Replacement gaskets are 1457JPG-10 (watertight) and 1457JEG-10 (EMI). The clear anodized version of this part is 1457J1201, and the flanged version is 1457J1202BK. The 1457J1201BK ships shrink-wrapped at 0.2 lbs (0.09 kg).
