How durable are the electronics?
The electronics are very dependable. The circuit board is completely potted* for protection from water and moisture. The electronics box can be easily replaced by removing one screw and disengaging two connectors. All connectors are UL®-listed and ROHS (Restriction of Hazardous Substances Directive)-compliant. * In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents.
