Omron D4NS Series Safety Interlock Switch, IP67, 31mm Width - D4NS-9AF
This safety interlock switch is designed to monitor access to guards and machine doors in industrial automation environments. It provides secure confirmation of door position using a removable operation key and is intended for indoor use where the keyhole remains free from contaminants. The unit features a plastic enclosure with screw terminals and is available with an M12 conduit/connector option to simplify wiring and replacement.
Features & Benefits
• IP67-rated enclosure offering dust- and water resistance during operation
• Direct-opening NC contacts ensuring safe circuit interruption
• Two auxiliary contacts delivering additional control or signalling capability
• Contact ratings suitable for 110V AC switching at 50 mA for micro-loads
• Power-to-lock/unlock function enabling mechanical interlocking control
• Compact length of 96mm for space-constrained installations
• Direct-opening NC contacts ensuring safe circuit interruption
• Two auxiliary contacts delivering additional control or signalling capability
• Contact ratings suitable for 110V AC switching at 50 mA for micro-loads
• Power-to-lock/unlock function enabling mechanical interlocking control
• Compact length of 96mm for space-constrained installations
Applications
• Suitable for automated production lines requiring door position monitoring
• Ideal for safety interlocks on press and forming machinery
• used with control panels needing additional auxiliary signalling
• Can be used for retrofit projects where M12 connector access is required
• Suitable for safety monitoring in electronics assembly cells

What terminals are provided for field wiring and how are they installed?
Screw-type terminals are provided
use AWG22 to 20 (0.5 to 0.75 mm²) conductors and tighten Terminal screws to the specified torque to ensure proper contact and cover fit.
How does the unit cope with different mounting orientations?
The head can be rotated to four mounting directions by loosening the head clamping screws, allowing flexible key insertion orientations.
What operating endurance can be expected under resistive loads?
Mechanical durability is rated to at least 1,000,000 operations and electrical durability is specified up to 500,000 operations for a 3A resistive load at 250 VAC and 300,000 operations for a 10A resistive load at 250 VAC.
Are there environmental or installation limits to observe?
Do not use outdoors or where corrosive gases, oil, water ingress through the keyhole, or severe vibration are present
the keyhole itself is not sealed to IP67.
What connector recommendations are given for maintaining enclosure protection?
Use compatible connectors with short thread engagement and appropriate seal packings
tighten conduit or connector to the specified torque and apply sealing tape for IP67 retention.
Note
Actuators are sold separately.
