An electronics enclosure has terminal conductors for contacting corresponding conductors in a receptacle when engaged with the receptacle. The electronics enclosure has a housing having first, second, third, fourth, fifth and sixth surface portions arranged to define the exterior of the housing. The receptacle engages and retains the corresponding electronics enclosure, the receptacle having terminal conductors for contacting corresponding conductors in the enclosure when engaged with the enclosure. The receptacle has a base surface along which the enclosure can translate in an engagement direction to engage the enclosure with the receptacle. An absorbent article management system includes: a diaper having the receptacle at which sensor elements of the diaper terminate; a logger unit having logger electronics enclosed in the enclosure and adapted to cooperate with the receptacle to connect the logger electronics to the sensor elements; and data processing equipment for processing data acquired from the sensor elements by the logger and for taking action based on the same.
