Ratings
General-purpose Ratings
Refer to these ratings before using the product.
Screw Terminal Models
Note:
Only for high-sensitivity overtravel models.
Direct-wired/Pre-wired Models
Note: 1.
The above figures are for standard currents.
2.
Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
3.
Lamp load has an inrush current of 10 times the steady-state current.
4.
Motor load has an inrush current of 6 times the steady-state current.

Characteristics
Note: 1.
The figures in parentheses for dielectric strength, are those for overtravel (high-sensitivity) or connector models.
2.
The values are calculated at an operating temperature of 5
°
C to 35
°
C, and an operating humidity of 40% to 70%. Contact your OMRON
sales representative for more detailed information on other operating environments.
