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 .
