Omron D4B-@N Series Limit Switch, 30mm Depth, IP67 - D4B-4571N

This limit switch is a Compact safety device designed to detect mechanical position changes and provide electrical switching in industrial automation environments. Housed in a metal enclosure with robust sealing, it is intended for control and safety applications where reliable contact separation and environmental resistance are required. It is suitable for assembly lines, machine guards and motion-control systems operating across a wide temperature range.

Features & Benefits

• Aluminium housing provides Durable protection in hostile environments
• IP67-rated sealing preserves internal components from dust and immersion
• 1NO 1NC slow-action contacts for controlled switching behaviour
• Direct-opening mechanism ensures NC contacts separate on fault conditions
• Mechanical life rated to 30,000,000 operations for extended service
• Switching capability up to 400V AC and 250V DC for varied loads

Applications

• Suitable for position sensing on conveyors and transfer systems
• Ideal for safeguarding machine guards and interlock monitoring
• Used with actuated doors and chutes in material handling plants
• Can be used for limit detection on presses and automated tooling
• Suitable for OEM equipment requiring multi‑directional mounting

What conduit entry options are provided for cable installation?

The enclosure accepts an M20 conduit entry to secure cable glands and connectors.

How are electrical connections terminated inside the unit?

Terminals use M3.5 Terminal screws compatible with 0.5 to 2.5mm² crimped leads.

What operating temperature range can the device withstand?

It is rated to operate from −40 °C up to 80 °C without icing.

How is mounting flexibility achieved for varied installation orientations?

The head can be rotated and the actuator repositioned to allow multi‑directional mounting.

What protective and certification standards does the switch meet?

It holds multiple safety and regional certifications and meets recognised enclosure protection ratings.
