Information About 440G-A27143

The Allen-Bradley 440G-A27143 Fully Flexible Actuator is part of the Guardmaster GD2 safety interlock system, offering superior adaptability for safeguarding machine access points. Its flexible design allows the actuator to maintain correct alignment with the GD2 interlock switch even when guard doors experience misalignment, vibrations, or frequent movement—conditions that can cause rigid actuators to fail. Built with industrial durability in mind, the 440G-A27143 features a robust split-crucible style actuator engineered for long service life. The flexible blade construction accommodates multiple mounting orientations and provides smooth mechanical engagement with the interlock switch every time. Designed to meet global safety and compliance requirements, the actuator carries certifications including C-TICK, CCC, and KC, assuring compatibility across international installations.

Key Features:

  • Fully flexible actuator for 440A GD2 safety interlock switches
  • Ideal for misaligned or frequently moved guard doors
  • Robust split-crucible design
  • Supports reliable safety interlocking in harsh industrial environments
  • Compatible with Guardmaster 440A GD2 switches
  • Meets global standards: C-TICK, CCC, KC
  • Compact dimensions for easy installation: 2.05" L × 0.79" W × 2.01" H

As part of the Allen-Bradley Guardmaster suite of safety products, this actuator integrates seamlessly with machine safety systems, enhancing reliability, uptime, and operator protection in industrial environments.

Frequently Asked Questions about 440G-A27143
Question: What is the 440G-A27143 and what does it do?
Date Update:16/06/2025
Answer:

The 440G-A27143 is a non-contact, RFID-coded safety interlock switch with guard locking, used to detect the presence and position of safety guards, doors, or panels. It ensures machines can only operate when guards are closed and properly latched.

It is designed for:

  • Category 4 / PLe safety applications (ISO 13849-1)
  • High-security applications where tamper-resistance and reliability are crucial
Question: How does the 440G-A27143 operate?
Date Update:16/06/2025
Answer:

This switch operates using RFID (Radio Frequency Identification) technology for the actuator. It ensures only the coded actuator that matches the sensor can enable operation.

The locking mechanism keeps the guard locked until:

  • The system determines it’s safe to release (e.g., machine stopped)
  • The correct release signal is received from the safety controller or PLC
Question: What are the key specifications of the 440G-A27143?
Date Update:16/06/2025
Answer:
  • Safety Standards: PLe, SIL 3, Category 4
  • Locking Type: Power-to-lock (guard remains unlocked without power)
  • Enclosure Rating: IP69K (ideal for washdown and food-grade environments)
  • Housing Material: Typically thermoplastic or stainless steel variants
  • Operating Voltage: 24V DC nominal
  • Connector: M12, 8-pin or prewired cable option

Exact specs should be confirmed via datasheet depending on the revision or suffix.

Question: How is the 440G-A27143 wired?
Date Update:16/06/2025
Answer:

Wiring configuration (typically via M12 connector):

  • 24V DC input to power the switch
  • OSSD outputs for safety monitoring
  • Lock/unlock control inputs
  • Diagnostic outputs (optional, depending on model)

The device integrates with GuardLogix, FlexSafety, or safety relays using dual-channel OSSD outputs.

Question: How is the 440G-A27143 installed?
Date Update:16/06/2025
Answer:
  1. Mount the sensor and actuator on fixed and movable parts of the guard, respectively.
  2. Ensure precise alignment to maintain operating tolerance.
  3. Connect via M12 plug or wire terminal according to the connection diagram.
  4. Program the RFID actuator if required (some models offer teach-in mode).
  5. Validate proper operation with safety controller.

Use stainless steel brackets or shock-resistant mounting kits in harsh environments.
