Omron D4GL-2AFA-A4 Interlock Solenoid Release: Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2AFA-A4 is a DPST interlock solenoid release switch designed for panel disconnect applications. This component features a 24VDC supply voltage, 240VAC circuit rating, and 102kgf holding force with IP67 ingress protection. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for existing installations and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2AFA-A4 is based on the following critical parameters that define functional equivalence:

Common Functional Parameters:

• Manufacturer: Omron Automation and Safety (same manufacturer ensures design compatibility)
• Circuit Configuration: DPST-NO/NC (DB/DM) x 2 (identical switching architecture)
• Actuator Type: Panel Disconnect (same mechanical interface)
• Conduit Thread Size: G1/2 (identical mounting specification)
• Operating Temperature Range: -10°C to 55°C (identical thermal operating window)
• Ingress Protection: IP67 (identical environmental sealing)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

Substitution Constraints: The D4GL-2AFA-A4 operates at 24VDC supply with 240VAC circuit rating and 750mA AC current capacity, delivering 102kgf holding force. The identified substitute parts operate at different voltage ratings (120VAC/125VDC) and reduced holding force (6kgf), indicating these are functional alternatives for applications where the lower holding force and different voltage specifications are acceptable. Termination style differences (Screw Terminal vs. Connector) represent mechanical interface variations that must be evaluated against installation requirements.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2AFA (Screw Terminal Configuration): This part is active and maintains identical circuit configuration, actuator type, mechanical mounting, and environmental specifications as the D4GL-2AFA-A4. The screw terminal termination matches the original part. Approval certifications include CCC, CE, cURus, and TUV, providing broader regulatory coverage than the obsolete original. Selection is appropriate for applications where the reduced holding force (6kgf versus 102kgf) and different voltage specifications (120VAC/125VDC versus 240VAC/24VDC) are compatible with system requirements.

D4SL-N2AFA-N (Connector Configuration): This part is active with identical functional specifications to D4SL-N2AFA, with the distinction of connector-based termination rather than screw terminal. Selection requires confirmation that the connector interface is compatible with existing installation infrastructure. Regulatory certifications and environmental specifications remain equivalent to D4SL-N2AFA.

Both substitute parts address the obsolescence of the D4GL-2AFA-A4 while maintaining core functional compatibility in circuit architecture, mechanical interface, and environmental protection ratings.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2AFA or D4SL-N2AFA-N directly replace D4GL-2AFA-A4 in existing installations?

A: Direct replacement requires verification that the application tolerates the reduced holding force (6kgf versus 102kgf) and different voltage specifications (120VAC/125VDC versus 240VAC/24VDC). The circuit configuration, actuator type, mounting thread, and environmental protection are functionally equivalent.

Q: What is the primary difference between D4SL-N2AFA and D4SL-N2AFA-N?

A: The termination style differs. D4SL-N2AFA uses screw terminals, matching the original D4GL-2AFA-A4 configuration. D4SL-N2AFA-N uses connector-based termination. All other electrical and mechanical specifications are identical.

Q: Are the regulatory certifications of the substitute parts equivalent to the original?

A: The substitute parts carry CCC, CE, cURus, and TUV certifications, providing broader regulatory coverage than the original D4GL-2AFA-A4 (CE, cULus, TUV). Both substitute parts meet or exceed the original certification requirements.

Q: What are the key parameters that determine substitution compatibility?

A: Circuit configuration (DPST-NO/NC), actuator type (Panel Disconnect), conduit thread size (G1/2), operating temperature range (-10°C to 55°C), and ingress protection (IP67) must remain constant. Holding force, voltage ratings, and current ratings are application-dependent and must be evaluated against specific system requirements.

Q: Why is the holding force significantly lower in the substitute parts?

A: The D4SL-N series represents a different product line within the Omron solenoid release portfolio, optimized for different application requirements. The 6kgf holding force is suitable for applications requiring lower mechanical force, while the original 102kgf is designed for higher-force applications. Selection must align with specific load requirements.
