Overview
The Allen-Bradley 440N-G02123 is a Ferrogard GD2 magnetically actuated non-contact safety switch manufactured by Rockwell Automation for machine guarding and personnel protection. The Ferrogard range provides the reliability of non-contact switches, combined with greater tolerance to door misalignment, making it ideal for sliding, hinge, or lift-off guard doors in industrial automation environments.
Key Features
- 2 N.C. Safety contacts and 1 N.O. Auxiliary contact with Reed technology
- Internal non-resettable overload protection on safety contacts to help ensure they do not fail to danger
- Resilient stainless steel housing to protect against impacts in heavy duty applications
- No contact between sensor and actuator reduces the risk of debris contamination
- Simple setup and alignment which helps reduce installation costs
- Minimal maintenance requirements and fairly tamper-proof design
Technical Specifications
This non-contact safety switch is engineered to strict safety standards and industrial durability requirements.
Typical Applications
Non-contact safety switches by Allen Bradley Guardmaster are often used in industrial applications, such as machine guarding in factory production lines. The 440N-G02123 is particularly suited for:
- Sliding door machine guards
- Hinge-mounted safety gates
- Lift-off guard applications
- Hazardous area access control
- Heavy-duty industrial machinery protection
Compatibility & Replacements
The 440N-G02123 is part of the Allen-Bradley Guardmaster 440N series and functions as a drop-in safety solution for existing machine guard installations. This safety device can be used with Guardlink, a new safety linking technology from Allen Bradley GuardMaster that simplifies connection time while providing real-time diagnostic information over Ethernet IP, making it simple to identify the location of the device that has tripped the safety system. When replacing older safety switches, verify contact configuration (2NC/1NO) and voltage compatibility (24VDC) with your control system before installation.
