A: Overall sensor dimensions

B: Holes for additional mounting screws (optional)

In case the sensor is not mounted on a PCB and is connected with a cable the SDP800/SDP600 series cap is recommended.

Soldering

Standard wave soldering systems may be used for soldering SDP800 series sensors. Reflow soldering is not feasible and

may damage the sensor.

The sensor ports must be protected from solder splash and flux during soldering. Figure 4 shows an appropriate temperature

profile with maximum temperature values.

The characteristics of wave soldering machines vary, so any soldering setup must be tested before production use.
