1
Electromechanical relays are warranted for 100,000 closures only. Solid-state switching devices are recommended for applications requiring
fast cycle times or extended service life.
2
To effect IP65 (NEMA 4X) rating requires a minimum mounting panel thickness of 1.5mm (0.06 inch) and a surface finish not rougher than
0.000812 mm (0.000032 in.).
