Omron D4n Series Limit Switch, 240V Switching AC Voltage, IP67 - D4N-4A20


This limit switch is a Compact industrial safety device designed to detect mechanical position changes and provide prompt electrical switching in control systems. Housed in a plastic enclosure rated to IP67, it is intended for indoor automation and electrical installations where a roller actuator and a screw-terminal connection are preferred. The unit operates across a wide ambient temperature range and is suitable for multi-directional mounting to accommodate varied machine geometries.

Features & Benefits


• Snap-action contacts provide fast switching for control logic
• 10A switching capacity at 240V AC supports standard loads
• 250V DC switching rating allows low-voltage DC circuits
• Mechanical life of 15,000,000 cycles reduces replacement frequency
• Operating force 6.4N enables accurate actuation with light contact
• M20 conduit entry simplifies European cable gland fitment

Applications


• Suitable for conveyor end-of-travel detection in factories
• Ideal for actuator limit sensing on packaging machinery
• Used for safety interlocks on guard doors and enclosures
• Can be used for position feedback in material handling systems
• Suitable for retrofitting into industrial panels requiring IP67 protection

What Terminal type is provided for wiring?


Screw terminals are used to connect conductors

suitable for AWG20 to 18 equivalent wire sizes when using crimp terminals.

How does the device perform under Rapid switching?


Electrical durability is rated for several hundred thousand operations at typical resistive loads

confirm expected duty cycle against the specified electrical life for your load.

Is the actuator orientation fixed or adjustable?


The head can be rotated to multiple directions and levers can be changed or re-positioned to suit the approach angle of the operating dog.

What environmental limits apply to use?


The unit is rated to operate between −30°C and +70°C with up to 95% ambient humidity but should not be used outdoors or where hazardous gases or continuous oil ingress occur.

What protection class and insulation details are relevant?


The enclosure meets IP67 protection and the internal construction provides Class II double insulation with a rated insulation voltage of 300V.
