Omron D4NL-2CFG-B Guard Lock Safety-Door Switch Ultimate IP67 Protection

Product Features
1. Robust Safety Interlock
Compliant with EN ISO 14119 Type 2 standards, the D4NL-2CFG-B ensures that guard doors remain securely locked until hazardous machine motion has ceased. The **solenoid-lock / mechanical-release** logic provides fail-safe operation: power must be applied to unlock the guard, guaranteeing personnel safety during maintenance or setup.
2. IP67-Rated Durability
The switch housing and head are molded from impact-resistant thermoplastic, sealed to IP67 for complete protection against dust and powerful water jets. This makes the D4NL-2CFG-B ideal for wash-down environments found in:
- Food & beverage packaging lines
- Pharmaceutical manufacturing
- Outdoor or high-humidity machinery
3. High Holding Force & Direct Opening Action
minimum holding force of 1,300 N prevents unauthorized door opening under mechanical stress. In emergencies, **direct opening contacts** (60 N force, 10 mm travel) instantly break safety circuits, bringing machinery to a safe stop.
4. Clear Visual Status
An integrated **multi-voltage orange LED** offers at-a-glance indication of the guard status, reducing troubleshooting time and improving overall equipment effectiveness (OEE).
5. Flexible Installation
- G 1/2 conduit entry simplifies cable routing.
- Screw terminals** accept wires up to 2.5 mm².
- Adjustable head position allows mounting on left- or right-hinged doors.

Typical Applications
- Robotic work cells – Ensures doors stay locked during automatic operation.
- Injection molding machines – Prevents access to the mold area while the press is cycling.
- Conveyor systems – Secures maintenance hatches on high-speed lines.
