Omron D4B-@N Series Limit Switch, 400V Switching AC Voltage, IP67 - D4B-2171N

This limit switch is a rugged actuator device for industrial position sensing and motion control, designed to operate in automated, electrical and mechanical systems. It provides mechanically actuated changeover contacts with a roller plunger actuator and sealed metal enclosure to withstand demanding factory environments while integrating into control circuits requiring both normally open and normally closed switching.

Features & Benefits

• Direct opening NC contacts reduce risk of welded-contact faults
• Rated for 400V switching at 2A for moderate AC loads
• IP67 sealed aluminium housing for protection against ingress
• Operates across −40 to 80°C for wide temperature ranges
• Multi‑directional mounting enables flexible panel orientation
• Mechanical life up to 30,000,000 operations for long service

Applications

• Suitable for machine guard position monitoring in assembly lines
• Ideal for conveyor end‑of‑travel detection and indexing control
• Used with motor starter circuits requiring changeover inputs
• Can be used for automated door position sensing in plant rooms
• Suitable for safety interlock feedback in mechanical presses

What conduit entry options does it offer for cabling?

The unit provides a G1/2 conduit entry for secure threaded cable glands and connector installation.

How are electrical connections MADE and secured?

Termination is via M3.5 Terminal screws compatible with 20 to 14 AWG (0.5 to 2.5 mm2) conductors and crimp Terminals tightened to the specified torque.

Which contact configuration is available and how does it behave?

It includes one normally open and one normally closed contact with a certified direct‑opening mechanism applied to the NC contact to force separation if contact welding occurs.

What mechanical attributes support installation and durability?

The body is aluminium with reinforced head sealing, provision for earth/ground screws, and a Compact depth of 30mm to suit confined mounting spaces.

What operational speeds and frequencies are supported?

The device is designed for operating speeds from 1 mm/s up to 0.5 m/s with mechanical operation rates around 120 operations/minute.
