'''KFK-EA4XA'''/'''KFK-EA4XB''' (104-key), '''KFK-EA5XA''' (105-key), '''KFK-EA7XA''' (107-key) and '''KFK-EA9XA'''/'''KFK-EA9XB''' (109-key) are models of rubber dome over membrane keyboards from [[Mitsumi]]. [[Mitsumi KFK-EA4XT]]/EA5XT is almost identical from above, but lacks the cable management feature. [[Mitsumi KFK-EA4SA]]/EA5SA is also almost identical from above, but is thinner and has 0.2 mm less key travel.

==Description==
KFK-EA4XA and related models are fairly standard rubber dome keyboards. One notable feature (shared with [[Mitsumi KPQ-E99ZC]]) is Mitsumi's (at the time) patent pending design for adjustable cable length, where the unused portion of the cable can be wrapped around pegs on the underside of the case.

The 1998 datasheet lists only the 104- and 105-key models, with DIN-5 being the standard connector and PS/2 the optional connector. A 2000 datasheet covers the USB version, and a 2002 datasheet gives the connector for the non-USB models as Mini-DIN-6.

The models are:

{| class="wikitable row-headings"
! Connector !! 104-key   !! 105-key   !! 107-key   !! 109-key
|-
| AT        || KFK-EA4XA || KFK-EA5XA ||           || 
|-
| PS/2      || KFK-EA4XA || KFK-EA5XA || KFK-EA7XA || KFK-EA9XA
|-
| USB       || KFK-EA4XB ||           ||           || KFK-EA9XB
|}

The four layouts available in 2002:

*"BIG ENTER 104" (Asian 101 layout)
*"STANDARD ENTER 105" (ISO layout)
*"STANDARD ENTER 104" (ANSI layout)
*"STANDARD ENTER 109" (JIS layout)

"Standard enter" refers to ISO/JIS and ANSI enter according to layout. No 107-key layout is depicted.
