Omron D4n Series Limit Switch, IP67, 10A Switching Current - D4N-4220


This limit switch is a Compact roller‑actuated industrial device designed to detect mechanical position changes and control circuits in automated systems. It is housed in a plastic enclosure rated to IP67 for dust and water resistance and accepts an M20 conduit entry for straightforward wiring. The mechanism provides a combination of normally open and normally closed contacts with snap‑action operation suitable for electrical switching tasks across AC and DC supplies within typical industrial environments.

Features & Benefits


• Snap‑action contacts handle 240VAC and 10A for mains switching capability
• 1NO/1NC screw terminals enable standard wiring practices and secure connections
• Mechanical endurance 15,000,000 cycles reduces replacement frequency
• Operating range −30°C to +70°C supports harsh temperature environments
• Multi‑directional head mounting eases installation in confined machinery
• 6.4N reversing force permits predictable lever behaviour under load

Applications


• Suitable for conveyor end‑of‑travel detection in manufacturing lines
• Ideal for limit sensing on industrial presses and stamping equipment
• Used with machine guards to monitor door and gate positions
• Can be used for actuator position feedback in packaging machines
• Suitable for retrofit control panels requiring a waterproof switchover

What contact arrangement does it provide for control circuits?


It offers one normally open and one normally closed contact in a snap‑action configuration, allowing both make and break functions in a single device.

How should the device be protected against short circuits?


Use a gI or gG type fuse rated at 10A in series as the recommended short‑circuit protection per the device’s switching category guidance.

What Terminal connection method is specified for field wiring?


Screw terminals are provided

compatible wire sizes are AWG20 to AWG18 (0.5 to 0.75 mm2) with appropriate crimp terminals to avoid case interference.

Are there restrictions on actuator loading or mounting orientation?


The head can be rotated to multiple directions and the lever must be contacted at right angles

avoid applying oblique loads to prevent actuator or shaft damage.
