Our take
Sharp R-520LKT is an exact-code black countertop microwave listed at 2.0 cu. ft. and 1,200 W cooking output. AJ Madison spells out both the retailer model R520LKT and the manufacturer's MPN R-520LKT, and labels the product black. Sharp's R-520L family manual maps K to black, W to white and S to stainless, but its suffix guide does not decode the final T in this longer listing code; keep R-520LKT intact rather than silently normalizing it. The exact-code listing also documents a 16-in. turntable, nine Smart & Easy sensor settings, Keep Warm Plus, three reheat options and four defrost options. It publishes a 24 × 13 3/8 × 19 1/8-in. outside size and 41-lb. net weight. Separate black built-in kits are listed, but cabinet fit requires checking the specific kit and opening. The historical Amazon ASIN B0011UD5TQ failed to load, so the affiliate destination searches by full model code.
Consider R-520LKT if you want a roomy 2.0-cu.-ft. black countertop microwave with sensor presets and can fit its 24 × 19 1/8-in. footprint and 16-in. tray. Allow for a 41-lb. appliance and check the 120-V/15-A rating. If you intend cabinet installation, verify whether the 27- or 30-in. black kit matches your opening and follow its exact instructions..
Look elsewhere if you need a compact or lightweight oven, a current direct ASIN proven for R-520LKT, or a built-in bundle that includes an approved trim kit. Do not omit the final T from searches; its meaning is not documented in the reviewed family manual.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The exact-code listing provides capacity, output, black finish, countertop type and exact MPN rather than asking the buyer to infer the model from a family name.
- Nine sensor-food settings, four defrost choices, three reheat options and Keep Warm Plus add clearly named ways to handle common heating tasks.
- A 16-in. turntable and published interior/exterior dimensions make dish and counter fit easier to assess than cavity capacity alone.
- Optional black 27- and 30-in. kit codes are listed for buyers considering a cabinet installation.
What to weigh up
- The 24-in. width, 19 1/8-in. depth and 41-lb. weight call for substantial counter space and careful handling.
- The color key explains K as black but does not explain the full R-520LKT suffix, especially its terminal T; preserve the exact code.
- Trim kits are separate accessories, and the listing notes limits on cabinet/oven combinations; check the exact kit manual before planning cabinetry.
- Historical ASIN B0011UD5TQ returned HTTP 500, so there is no verified direct Amazon route for this exact model.

What the features mean for you
Keep R-520LKT intact and distinguish the black finish
AJ Madison identifies the exact MPN as R-520LKT and calls its color black. The Sharp family manual covers R-520K/R-520L models followed by a color letter and maps K to black, W to white and S to stainless steel. It does not explain the extra final T in the listing code. Retain R-520LKT as the source model; the verified black listing and family color key support the finish without guessing the T meaning. Row 24's unresolved R520LWK string is different and is not merged with this exact-code listing.
Compare cavity size and cooking output
AJ Madison lists 2.0 cu. ft. and 1,200 W cooking output, with 120 V/15 A electrical details. It gives dimensions as 24 × 13 3/8 × 19 1/8 in. outside and 17 3/8 × 10 1/2 × 18 5/8 in. inside. Use the output figure to compare microwave cooking power, and use the separate electrical rating when checking your supply. A large cavity does not replace measuring the full exterior or the route needed to lift the 41-lb. unit into place.
Use the named sensor settings
The exact-code listing describes nine Smart & Easy sensor foods: popcorn, fresh vegetables, frozen entrées, rice, baked potatoes, ground meat, poultry, fish and seafood. It says the controls adjust time and power. These concrete settings support sensorCooking=true for matching; a generic one-touch key alone would not establish a sensor. The same page lists three reheat options and four defrost options, which may matter if those routines match your regular cooking.
Check the 16-in. turntable against your dishes
The exact R520LKT page lists a 16-in. turntable. Compare that rotating diameter with your widest plate and include handles or a raised rim; a dish can be narrower than the tray yet still fail to rotate freely. AJ Madison also lists the interior width, height and depth, giving a second fit check for taller bowls and containers.
Treat built-in kits as a separate installation decision
The listing marks an optional built-in trim kit and names black kits RK-51K for a 27-in. cabinet width and RK-51K30 for 30 in. Its notes limit some installations over gas or electric wall ovens/warming drawers depending on kit. Verify the exact approved kit, cabinet opening and combination instructions before buying parts or cutting a cabinet. The countertop product page's kit flag does not make an arbitrary cabinet opening compatible.
Use a full-model Amazon search
The frozen record points to B0011UD5TQ, but its Amazon page returned HTTP 500 when checked on 2026-10-05. That does not prove a current exact-model ASIN. The tagged search carries the complete R-520LKT identifier so the buyer can inspect the current result; this review makes no price, availability or buyer-rating claim. Commercial-duty classification was not established in the reviewed sources and remains unknown.
What else to compare
If the 2.0-cu.-ft. cavity, 24-in. width or 16-in. tray is larger than you need, compare a smaller countertop model with documented dimensions and a compatible tray. If cabinet installation is the main reason for choosing this Sharp, verify the separate black trim kit and its detailed restrictions first. Preserve R-520LKT as a complete code because the final T is not decoded in the family manual.

The decision
Choose Sharp R-520LKT if you want a black 2.0-cu.-ft. countertop microwave with 1,200-W output, nine sensor settings, a 16-in. turntable and documented optional trim kits. Measure for its 24 × 19 1/8-in. exterior and 41-lb. weight, and confirm the separate kit's cabinet restrictions. The K color letter is mapped to black, but the terminal T remains unexplained. Historical ASIN B0011UD5TQ failed, so use the tagged exact-model search rather than a direct link.
