Characteristics
General-purpose Models/Environment-resistant Models
Note: 1.
The above figures are initial values.
2.
The figures in parentheses for dielectric strength, are those for the overtravel (high-sensitivity) model.
3.
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.
4.
10,000,000 operations min. for general-purpose, high-sensitivity, and flexible rod overtravel models.
5.
500,000 operations min. for high-precision and outdoor specifications models. All microload models however, are 1,000,000 operations
min.
6.
Except the flexible rod models. The shock resistance (malfunction) for microload models is 200 m/s

7.
For low temperature models this is –40
