1
Electromechanical relays warranted for 100,000 closures
only. Solid-state switching devices recommended for
applications requiring fast cycle times or extended service
life.
2
To effect NEMA 4X (I.P. 65) rating requires a minimum
mounting panel thickness of 0.06inch (1.5 mm) and surface
finish not rougher than 0.000032 inch (0.000812 mm).
3
Switching inductive loads (relay coils, etc.) requires using an
RC suppressor.
