Omron D4NL Series Solenoid Interlock Switch Power to Unlock 24V DC 2 NC Safety Contacts IP67

Omron D4NL-4CFA-B4 Solenoid Interlock Switch is a power-to-unlock industrial safety device with 24V DC supply voltage, designed to secure guarded doors and control hazardous area access. It features an IP67 rated plastic housing that ensures protection against dust and water ingress, making it suitable for demanding factory environments.

The switch offers two normally closed (NC) safety contacts designed for direct-opening safety circuits, accommodating microloads and standard loads with a contact current rating of 50mA. It supports both 110V AC and 250V DC voltages on its contacts, providing versatile applications in different circuit configurations.

Measuring compactly at 35.5mm depth, 95mm width, and 88.5mm length, this unit fits well within constrained installation spaces. The device includes an M20 conduit entry for standard cable gland mounting, ensuring secure and reliable electrical connections.

Certified to international standards such as CE, UL, UL508, EN60947-5-1, and CSA C22.2 No.14, the D4NL-4CFA-B4 meets stringent safety requirements expected in industrial automation and machinery guard interlocks. It operates as a power to unlock mechanism, controlling access during machine operation through electromagnetic locking and auxiliary monitoring features.

Its common industrial applications include interlocking machine guards on production lines, safety doors on material handling equipment, motor protection circuits using control contactors, and perimeter access control on robotic cells. The switch is suitable for retrofit replacements where M20 conduit entry is already installed.
