An absorbent article management system comprising: a diaper having a receptacle at which sensor elements of the diaper electrically terminate, the receptacle having terminal conductors arranged to contact corresponding conductors in an enclosure when engaged with the enclosure, the receptacle having a base surface along which the enclosure can translate in an engagement direction to engage the enclosure with the receptacle; a logger unit having logger electronics enclosed in the enclosure, the enclosure being adapted to cooperate with the receptacle to connect the logger electronics to the sensor elements when the enclosure is engaged with the receptacle; and data processing equipment for processing data acquired from the sensor elements by the logger and for taking action based on the same, the electronics enclosure having terminal conductors for contacting corresponding conductors in the receptacle when engaged with the receptacle, the electronics enclosure having a housing, the housing having first, second, third, fourth, fifth and sixth surface portions (101a, 101b, 101c, 101d, 101e, 101f) arranged to define the exterior of the housing, the first and second surface portions (101a, 101b) being respectively front and rear surface portions in an engagement direction of the enclosure with the receptacle, the third and fourth (101c, 101d) surface portions each connecting the first and second surface portions, the fifth and sixth surface portions (101e, 101f) each connecting the first and second surface portions and each connecting the third and fourth surface portions and being spaced apart in a direction other than the engagement direction, the housing having no more than one plane of symmetry which includes the engagement direction, and the third and fourth surface portions being relatively inclined to approach each other in the engagement direction from the second to the first surface portion. a diaper having a receptacle at which sensor elements of the diaper electrically terminate, the receptacle having terminal conductors arranged to contact corresponding conductors in an enclosure when engaged with the enclosure, the receptacle having a base surface along which the enclosure can translate in an engagement direction to engage the enclosure with the receptacle; a logger unit having logger electronics enclosed in the enclosure, the enclosure being adapted to cooperate with the receptacle to connect the logger electronics to the sensor elements when the enclosure is engaged with the receptacle; and data processing equipment for processing data acquired from the sensor elements by the logger and for taking action based on the same, the electronics enclosure having terminal conductors for contacting corresponding conductors in the receptacle when engaged with the receptacle, the electronics enclosure having a housing, the housing having first, second, third, fourth, fifth and sixth surface portions (101a, 101b, 101c, 101d, 101e, 101f) arranged to define the exterior of the housing, the first and second surface portions (101a, 101b) being respectively front and rear surface portions in an engagement direction of the enclosure with the receptacle, the third and fourth (101c, 101d) surface portions each connecting the first and second surface portions, the fifth and sixth surface portions (101e, 101f) each connecting the first and second surface portions and each connecting the third and fourth surface portions and being spaced apart in a direction other than the engagement direction, the housing having no more than one plane of symmetry which includes the engagement direction, and the third and fourth surface portions being relatively inclined to approach each other in the engagement direction from the second to the first surface portion.
