Omron D4n Series Limit Switch, IP67, 1 NO/1 NC Contact Configuration - D4N-4A2H


This limit switch is a Compact mechanical position sensor designed for industrial control and automation tasks. Housed in metal with sealed internals, it provides rugged switching for machinery interfaces where a small, multi‑directional actuator is required. The unit is intended for indoor industrial environments and connects via an M20 conduit entry to conventional wiring systems.

Features & Benefits


• IP67 ingress protection for dusty and wet environments
• Snap‑action contacts enabling quick response switching
• 1 NO and 1 NC arrangement with screw terminals for simple wiring
• Mechanical durability rated at 15,000,000 cycles for long service life
• Operating force 4.5 N for consistent actuation under variable loads
• Ambient operating range −30 to +70°C for broad temperature use

Applications


• Suitable for detecting end‑of‑travel on conveyor systems
• Ideal for position sensing on packaging machinery
• used with industrial actuators for repetitive cycling tasks
• Can be used for safety interlocks in machine assemblies
• Suitable for integration into control panels with M20 conduit

How are electrical connections MADE to the device?


Wiring is via screw‑type terminals designed for AWG20 to AWG18 (0.5 to 0.75 mm2) conductors and accepts standard conduit connectors at the M20 opening.

What mounting flexibility does it offer for confined installations?


The head can be oriented in multiple directions and the actuator can be set at discrete angular positions to suit limited‑access mounting points.

How does the internal contact mechanism behave under heavy duty?


The internal switching uses a snap‑action contact form with a direct‑opening mechanism on NC contacts to ensure forced separation even if contact deposits occur.

What environmental precautions are advised for reliable operation?


Avoid continuous immersion, aggressive chemicals, excessive vibration, and locations with corrosive gases or fine particulates that could reach the actuator head.

What thermal conditions limit continuous electrical load handling?


At ambient temperatures above 35°C, passing a 3 A, 250 VAC load through more than two circuits is not recommended to prevent performance degradation.
