* Temperature excursions to 225

°C for 2 minutes or less are permitted.

† All industry-accepted soldering techniques are permitted for these subassemblies provided the indicated maximum

temperature for each component (e.g., sensor face, plastic housing) is not exceeded. Reasonable dwell times, which do

not cause melting of the plastic housing, should be used.
