Datasheet - D4NS-8BF

Omron D4NS Series Safety Rated Interlock Switch, 240V AC Contact Voltage, IP67 - D4NS-8BF

This safety-rated interlock switch is a keyed device intended to prevent access to hazardous machinery by interrupting power when a guarded door is opened. Designed for industrial control panels and machinery enclosures, it provides monitored safety contacts and auxiliary outputs for integration into control systems while withstanding typical plant environments.

Features & Benefits

• IP67 protection for the switch body ensuring dust and water resistance
• Two safety NC contacts providing direct-opening safety function
• Two auxiliary contacts enabling auxiliary monitoring and signalling
• Rated for 240V AC switching at 3A for standard loads
• Operating range from -30 °C to +70 °C for varied plant conditions
• Resin housing and Compact footprint for lightweight panel mounting

Applications

• Suitable for guarding on automated assembly lines
• Ideal for interlocking access to electrical control cabinets
• Used with safety controllers for door-status monitoring
• Can be used for stop/start permissive circuits on conveyors

What conduit options are provided for cable entry?

This variant accepts an M20 conduit entry and is compatible with recommended M20 connectors and sealing practices to maintain enclosure integrity.

How do the contacts perform under differing load conditions?

The safety contacts switch resistive loads up to 3A at 240V AC and are gold-clad for improved reliability on both standard and micro loads.

What mechanical durability can be expected for frequent operation?

Mechanical endurance is specified at a minimum of 1,000,000 operations and electrical durability is rated for 500,000 operations under defined resistive loading.

What installation considerations affect sealing and performance?

Keep the keyhole free from oil, water and metal chips, apply sealing tape at conduit joints, and tighten connectors to the specified torque to preserve IP67 for the switch body.
