'''Y-RJ20''' is the keyboard component of one of Logitech's '''Cordless Keyboard MX''' sets, which contains a cordless mouse and keyboard that connect to the computer via a base station.

==Description==
The keyboard features a volume knob with an opto-mechanical [[rotary encoder]] in addition to all the multimedia buttons. Unusually, the keyboard features dedicated legends for the [[command key]] and [[option key]] for use with Macintosh computers, with the command and option keys in their correct locations.

The [[function keys]] default to multimedia functionality, with F1-F12 [[side-printing|side-printed]] along the front.

The keyboard has a detachable [[wrist rest]].

The frequency range is 26.96−27.28 MHz.

==Origin==
The keyboard pictured below bears the following details:

 M/N:  Y-RJ20
       RT7R04 V:5XTWUK
 P/N:  867281-0120
       967335-0120 A

In the case of the [[Dell KB522]], all indications are that Logitech was Dell's OEM for that keyboard. In this case, however, the rear label clearly bears an [[NMB]] model number, RT7R04, below Logitech's own model number. The internals appear to be wholly devoid of any manufacturer names, but the pictured keyboard has only been 90% disassembled.
