SBE and SBX connectors build on the capability of the SB^® connectors that handle two primary power contacts with the capacity to have up to 8 auxiliary power / signal contacts. The centers of the connector housing's feature a location for either: two PP15-45 housings and contacts, an innovative 1x4 auxiliary accessory, or two PPMX housings that can accommodate up to 8 aux contacts. In addition, the housings meet IEC 60950 & IEC60529 touch safe requirements.

Sequencing within auxiliary positions is possible using the 4 pin lengths available in the 1x4 auxiliary accessory however the auxiliary contacts mate last / un-mate first in relationship to the power contacts. While SBE and SBX housings offer similar capabilities, the SBE connector housings are molded from a chemical resistant PBT/PC blend resin allowing them to meet EN1175:2020 requirement and are tested to EN1175:2020 standards. SBX are molded from a rugged PC resin that is more impact resistant and are tested to UL/CSA requirements.
