5. Environmental ConditionsStorage temperature -40to+60˚C

Storage humidity 10to95%RH

6. Recommended Process ParametersGluingTypes of glue Cyanoacrylates(non-blooming),i.e.Loctite401,408,460and

Sicomet 50, 63, 77

Non-blooming types must be used to ensure that residuals from the curing process do not degrade the component.

SolderingSoldering temperature and time 300˚C[572˚F]for3sor350˚C[662˚F]for1s

Soldering distance Min.0.5mm[0.02”]fromhousing

To prevent damage to the carbon taper as a result of the solder-ing process, the knob must be turned either fully CW or CCW, opposite to the switch position.

Mechanical stress on soldering terminals must be avoided during soldering.

CleaningCleaning solvents Aquawash(Alpha2110),Benzine

Ultrasonic cleaning must be avoided as it may remove the lubri-cant inside the component
