Aqueous rinse suitable. Proper dryingnecessary.|Fully Sealed|| ## Handling & Assembly Instructions - Switching inductive and/or capacitive loads create voltage and/or current peaks, which may damage the relay. Protective circuits need to be used - see our website. External magnetic fields and magnetic effects, due to adjacent relays in high density matrices that may influence the relays' electrical characteristics, must be taken into consideration. Mechanical shock impacts, e.g. dropping the relays, may cause immediate or post-installation failure. Suppressing coil diode can have a negative influence on total number of switching cycles, especially by switching high voltage - Wave soldering: maximum 260°C / 5 seconds. ## ~~LC~~ Glossary Contact Form |Form A|Form A|NO = Normally Open Contacts
