Note: The above values are initial values.
*1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing
properties are sufficient for the operating conditions and environment beforehand. 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
enter through the key hole on the head, otherwise Switch damage or malfunctioning may occur.
*2. The durability is for an ambient temperature of 5 to 35°C and an ambient humidity of 40% to 70%. Contact your
OMRONsales representative for more detailed information on other operating environments.
*3. These figures are minimum requirements for safe operation.
