Lumidigm M-Series M3xx Modules Mechanical Integration Guide, PLT-02217, Rev. A.0
The Lumidigm M3xx product line includes sensors with an enclosure. These products use
the mounting technique described in Figure 8. The details of the clip used in this design are
shown in Figure 9. The clip material is a flexible plastic that opens sufficiently to slide into
place over the M3xx sensor head enclosure and securely grip the mounting features
present. Note: M3xx modules do not ship with a mounting clip. 3D CAD models and
samples of the clip shown are available from HID Global.

Once exterior features are determined, the next consideration is to determine the nature of
the seal to be used between the sensor platen area and the internal surfaces of the features
which capture and attach the M3xx sensor head to the customer enclosure. Once the
overall sealing strategy and rating requirements are determined and a gasket material is
selected, the next consideration is to determine the pressure set of the gasket required to
achieve the seal rating required.
