Abstract
A linear measuring arrangement for measuring a relative position of two objects. The linear measuring arrangement includes a unit having a housing and a scale in the housing and a scanning unit, which can be shifted relative to the unit in a measuring direction, wherein the scanning unit is arranged inside the housing and includes a heat-generating electrical component. The arrangement further includes a mounting piece, which is fastened to the scanning unit by a coupling, which is rigid in the measuring direction and resilient transversely thereto, and which extends to a mounting area arranged outside of the housing. The arrangement further includes a heat-conducting element, which is designed for transferring heat generated by the heat generating electrical component to the mounting piece and permits relative movements between the mounting piece and the scanning unit at least transversely to the measuring direction.
