3 Physical Dimensions and Mounting Information

3.1 Housing

The SDP1108-R differential pressure sensor is mounted

in chemically inert PPS housing. The rugged package

has

been

designed

to

withstand

continuous

overpressures of at least 1 bar (14.5 PSI). Burst pressure

is > 2 bar (29 PSI)

The physical dimensions and mounting information is

given in Figure 1 and 2.

Figure 1: Pin out and physical dimensions in mm (inch). The

drawing is not to scale.

Figure 2: SDP1108-R PCB footprint. The drawing is

not to scale.

3.2 Soldering Instructions

The SDP1108-R differential pressure sensor can be

wave soldered. Direct reflow soldering is not

recommended since it may affect the accuracy.

If reflow soldering is required Sensirion recommends to

use an SMD connector (e.g. type Samtec SSM-103-L-

SV) and to mount the SDP1108-R after soldering.
