1Electromechanical relays warranted for 100,000 closures only.

Solid-state switching devices recommended for applications

requiring fast cycle times or extended service life.

2To effect IP65 (NEMA 4X) rating requires a minimum mounting

panel thickness of 1.5 mm (0.06 inch) and surface finish not

rougher than 0.000812 mm (0.000032 inch).

3Switching inductive loads (relay coils, etc.) requires using an RC

suppressor.
