Rated IP67, it withstands washdown environments in food processing or machine-tool cells. Switching capacity is 3 A at 240 V AC or 270 mA at 250 V DC — the DC rating is derated significantly from the AC figure, so verify the load type before committing the BOM line. ## Dimensions & Mounting The switch body measures 35.5 mm deep by 88.5 mm wide by 95 mm high. Screw terminals accept standard wiring; strip length and torque are per the datasheet. The four head directions allow the actuator key to enter from top, bottom, left, or right — useful when retrofitting into an existing guard frame without reworking the door profile. ## Electrical Endurance Rated for 500,000 electrical cycles and 1 million mechanical cycles. The electrical life is tested at the rated AC load; inductive or DC loads will reduce cycle count. For high-frequency door cycling (over 10 operations per hour), factor in earlier contact replacement.","metaTitle":"Omron D4NL4DFGB Safety Door Lock Switch, 4NC, IP67, Screw Te","metaDescription":"D4NL4DFGB safety door lock switch with solenoid lock, 4NC contacts, IP67, screw terminal.
