PERFORMANCE
NOTES
1 . The RC4B2 connector is designed to mate with an RC422 connector using contact option
-21 (0 .270” long) and -39MT hardware . This contact length and hardware combination
assures proper connector mating when using boards having a thickness of 0 .058” –
0 .125” .
2 . When guide hardware is required on the RC4B2 connector, use hardware option -3900 on
the mating connector .
3 . When jacksocket hardware is required on the RC4B2 connector, use hardware option
-39MT on the mating connector .
Contact Rating: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 amperes
Operating Temperature: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65° C to +125° C
