Hammond 1458A3 4x4x3 in Steel Instrument Case, Satin Black

The 1458A3 is a solid top and bottom steel instrument case in satin black (Black RAL 9011), measuring 4.00 in wide by 4.00 in deep by 3.00 in high. As the smallest footprint in the 1458 range, it is a good fit for small signal conditioners, sensor interfaces, power supplies and single-board projects, whether for OEM production runs, lab equipment or one-off test gear.

The top and bottom halves are heavy duty 18 gauge steel. The two end panels are easy-to-machine 0.064 in thick aluminum, one satin black and one contempra grey, and the symmetrical design lets either end panel serve as the front or the rear. That makes it straightforward to cut connector, switch and display openings in aluminum rather than steel.

The 1458A3 is supplied as an assembly of top, bottom, black end plate, grey end plate, 8 enclosure screws and 4 rubber feet. The 6-32 Philips screws are nickel plated, and Hammond recommends a cover screw torque of 125-150 cN-m (11-13.3 lbf-in). Replacement nickel plated #6-32 x 1/4 in self-tapping enclosure screws are part 1421J8, and spare rubber feet are 1421T3 (pack of 24).

Need custom cut-outs? Hammond states the enclosure can be factory modified (milling, drilling, printing) and offers solid models in .stp or .x_t. The 1458A3 ships in shrink wrap at 0.99 lbs (0.45 kg), is RoHS and REACH compliant, and is also offered as 1458A3B in satin blue and in vented-top versions (1458VA3, 1458VA3B).
