Omron D4A-N Series Limit Switch, 10A at 250 VAC Rated Load, Screw Terminal - D4A-1101N


This limit switch is a general-purpose mechanical device designed for industrial control and position detection in automation, electrical and mechanical systems. It features a sealed head and a modular block-mount design that simplifies assembly, reduces maintenance downtime and suits environments requiring protection against water and dust ingress. The unit is suitable where robust switching, Compact installation and compatibility with standard conduit sizes are required.

Features & Benefits


• Double-seal head providing IP67 protection and improved ingress resistance
• Operating temperature range from −40°C to 100°C for wide environmental use
• Mechanical life up to 50 million operations for long-term duty
• Electrical endurance up to 1 million operations at rated resistive loads for control reliability
• Multiple actuator heads available for versatile motion interfaces and mounting
• Earth Terminal and screw-type wiring for safe earthing and secure connections

**Applications**


• Suitable for conveyor end-of-travel detection in automated lines
• Ideal for motor rotation direction selection and speed control switching
• Used with packaging machinery requiring high-cycle switching
• Can be used for safety position sensing in assembly jigs and fixtures
• Suitable for control panels needing a screw-terminal, conduit-ready switch

What conduit and wiring interfaces does it support?


The receptacle accommodates common conduit threads and a plug-in style receptacle

screw Terminal wiring and M5/M4 mounting interfaces are provided for secure electrical and mechanical connections.

How does the modular construction assist maintenance?


The block-mount architecture allows the head, switch body and receptacle to be removed or replaced individually, reducing downtime and simplifying spares management.

What indicator options are available for status feedback?


Indicator choices include neon lamps and LEDs with specified rated voltages and internal resistances to suit AC or DC signalling requirements.

Which sealing and elastomer options exist for chemical resistance?


Standard sealing uses an oil-seal Plus X-ring arrangement and fluoro-rubber sealed variants are offered for enhanced chemical resistance and extended temperature capability.

What electrical switching capabilities are provided for complex control?


Configurations include single-pole double-throw and double-pole double-throw double-break contact forms, enabling simultaneous, sequential or centre-neutral operations for multi-circuit control.
