Abstract: An aftertreatment system comprises a housing including a sidewall and defining an internal volume. The housing is sized and configured to house at least one aftertreatment component within the internal volume. A sensor mounting table is coupled to the sidewall. The sensor mounting table includes a base and a plurality of legs extending from the base. Each leg of the plurality of legs includes a first portion and a second portion. The first portion extends orthogonally from the base towards the housing. The second portion extends outwardly relative to the base at a non-zero angle from an end of the first portion located distal from the base. The second portion is coupled to the sidewall of the housing, thereby coupling the sensor mounting table to the housing. At least one electronic module is removably coupled to the sensor mounting table.
