Omron D4NH Series Hinge Switch, 10A Contact Current, IP67 - D4NH-1BAS


This hinge switch is a Compact safety-door interlock designed for machine guarding and safety equipment in industrial automation environments. It provides sealed operation for protection against dust and temporary immersion and is suitable for use where temperature extremes and robust switching cycles are expected.

Features & Benefits


• IP67 rating provides waterproof protection for harsh environments
• 2NC contact configuration supports safety-circuit designs
• Rated for 10A at 240V AC to handle standard control loads
• 250V DC switching capability for DC control applications
• Mechanical life of 1 million operations for long service intervals
• Operates from −30°C to +70°C for wide ambient compatibility

**Applications**


• Suitable for safeguarding access doors on production machinery
• Ideal for integration into electrical safety interlock circuits
• Used with control panels requiring 2NC emergency monitoring
• Can be used for automated doors and enclosures with water exposure
• Suitable for retrofit where PG13.5 conduit entry is required

What Terminal arrangement is provided for wiring?


The unit uses a terminal-block arrangement allowing screw-terminal connection for field wiring and crimp terminals compatible with AWG20–AWG18.

How should I protect the switch from short-circuits?


A series fuse is recommended

use a 10A IEC60269 type gI or gG fuse as short-circuit protection.

How resistant is the switch to electrical transients?


It features impulse withstand voltages up to 6 kV between terminals and uncharged metal parts, with 4 kV between differing polarities.

Are there specific mounting or mechanical limits to observe?


Mount using M4 fasteners and adhere to specified tightening torques

avoid imposing forces of 50 N or more on the actuator shaft.

What switching behaviour applies to the NC contacts?


NC contacts include a direct-opening mechanism to forcibly separate contacts in case of metal deposition, conforming to direct-opening safety requirements.
