All published specifications.
Technical points to confirm
- Dimensions differ: 1380 × 1235 × 1540 mm in the product table versus 1430 × 1265 × 1540 mm in the range overview.
- The product title identifies NEX-450R-4S, while the shared parameter table identifies NEX-450R. A separate specification for the -4S suffix is not published.
- The 390 × 250 mm tray layout is repeated in the product table. The range overview additionally lists 180 × 155 mm, six trays per cycle.
- Product text claims a 35–40% efficiency increase; the range introduction says 35–45%. Neither specifies a test baseline, so these are not guaranteed output figures.
- The technical graphic gives conflicting two-tray dimensions of 390 × 250 mm in its table and 390 × 240 mm in its drawing, and a four-tray drawing of 240 × 180 mm versus 250 × 180 mm in the HTML table.
- Brochure header names NEX-450R; linked parameter section includes NEX-370R and NEX-450R.
