D4BS
Characteristics
Note: 1.
The above values are initial values.
2.
Although the switch box is protected from dust, oil, or water penetration, do not use the D4BS in places where dust, oil, water, or chemicals
may penetrate through the key hole on the head, otherwise Switch damage or malfunctioning may occur.
3.
The durability is for an ambient temperature of 5
°
C to 35
°
C and an ambient humidity of 40% to 70%. Contact your OMRON sales rep-
resentative for more detailed information on other operating environments.
4.
These figures are minimum requirements for safe operation.
