The 7-525D is a 3U aluminum open rack chassis panel from the Hammond 7- Series, intended for engineers, integrators and lab technicians who need a blank, workable surface for mounting custom electronics in a 19 in rack. Its formed, open construction makes it a practical starting point for custom front panels, instrumentation faces and prototype assemblies where off-the-shelf enclosures do not fit the design.
The chassis is formed from 0.06 in thick 5052H32 aluminum (the drawing notes 0.064 in aluminum), giving lightweight, corrosion-resistant support for PCBs, connectors, switches and controls. The natural aluminum finish can be painted, labelled or machined as required, and the open design allows drilling and modification during development without special tooling.
Overall dimensions are 5.22 in (133 mm) high, 17.00 in (432 mm) wide and 5.25 in (133 mm) deep, with a 19.00 in (483 mm) mounting width across the flanges and a nominal listed size of 5.25 in x 19 in x 5.25 in (133 mm x 483 mm x 133 mm). The part occupies 3 rack units. Mounting is via four 0.25 x 0.375 in (6 mm x 13 mm) slots spaced 18.32 in (465 mm) apart, with 0.12 in (3 mm) corner radii; mounting hardware is not included. Shipping weight is 2 lbs (0.91 kg).
The 7-525D is TAA-compliant and manufactured in North America (country of origin CA) in an ISO 9001 certified facility, and is RoHS, REACH and USMCA compliant. Listed accessories for the series include hardware for rack mounting solutions, a hinged solid rack security cover and a hinged solid rack security door. The panel is part of Hammond's Legacy Portfolio, offered for over 50 years.
