Omron D4GL-2AFG-A Interlock Solenoid Locking Switch: Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2AFG-A is an interlock solenoid locking switch designed for panel disconnect applications with dual-pole, single-throw configuration (DPST-NO/NC). This component operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf. The D4GL-2AFG-A is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-2AFG-A is based on the following critical parameters that must align across equivalent parts:

Mandatory Compatibility Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Locking
• Circuit Configuration: DPST-NO/NC (DB/DM) x 2
• Actuator Type: Panel Disconnect
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C to 55°C
• Ingress Protection: IP67 - Dust Tight, Waterproof

Allowable Variations:

• Current Rating: The D4GL-2AFG-A operates at 750mA AC. Substitute parts with higher current ratings (1.5A AC) are acceptable as they provide greater capacity.
• Voltage Rating: The D4GL-2AFG-A operates at 240VAC with 24VDC supply. Substitute parts with different voltage ratings (120VAC, 125VDC) represent different application configurations but maintain the same functional architecture.
• Holding Force: The D4GL-2AFG-A provides 102kgf. Substitute parts with lower holding force (6kgf) indicate different mechanical load requirements and represent a significant functional change.
• Termination Style: Screw Terminal (original) versus Connector (substitute) represents a mechanical interface variation.

The D4SL-N series parts (D4SL-N2AFG and D4SL-N2AFG-N) meet the mandatory compatibility parameters and are classified as active products, making them suitable substitutes for the obsolete D4GL-2AFG-A.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2AFG (Screw Terminal Configuration)

The D4SL-N2AFG is an active product suitable for applications requiring screw terminal connections. This part maintains the same termination interface as the original D4GL-2AFG-A, minimizing installation modifications. The D4SL-N2AFG carries expanded regulatory approvals (CCC, CE, cURus, TUV) and holds REACH Unaffected status, providing enhanced compliance documentation for new designs and system certifications.

D4SL-N2AFG-N (Connector Configuration)

The D4SL-N2AFG-N is an active product configured with connector termination, offering simplified installation and maintenance procedures compared to screw terminal designs. This part is suitable for applications where connector-based interfaces are preferred or required by system architecture. Like the D4SL-N2AFG, it carries expanded regulatory approvals and REACH Unaffected status.

Critical Considerations

Both substitute parts operate at 120VAC/125VDC, representing a different voltage class than the original 240VAC/24VDC specification. System voltage compatibility must be confirmed before implementation. The substitute parts provide 6kgf holding force compared to the original 102kgf, indicating a significant reduction in mechanical load capacity. Applications requiring the original holding force specification cannot use these substitutes without mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2AFG or D4SL-N2AFG-N directly replace the D4GL-2AFG-A in existing installations?

A: Direct replacement is possible only if the system operates at 120VAC/125VDC voltage levels and the application load does not exceed 6kgf holding force. The original D4GL-2AFG-A operates at 240VAC/24VDC with 102kgf holding force. Voltage and mechanical load compatibility must be confirmed before substitution.

Q: What is the primary difference between D4SL-N2AFG and D4SL-N2AFG-N?

A: The D4SL-N2AFG features screw terminal connections, while the D4SL-N2AFG-N uses connector termination. Both parts are electrically and functionally identical. Selection depends on installation requirements and system interface specifications.

Q: Are the substitute parts compliant with the same regulatory standards as the original?

A: The substitute parts carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original (CE, cULus, TUV). Both substitute parts hold REACH Unaffected status, providing enhanced environmental compliance documentation. The original part status is listed as Vendor Undefined for REACH compliance.

Q: What is the current rating difference between the original and substitute parts?

A: The D4GL-2AFG-A is rated at 750mA AC. The D4SL-N series parts are rated at 1.5A AC and 220mA DC. The higher AC current rating of the substitutes provides greater electrical capacity and is acceptable for applications originally designed for 750mA AC operation.

Q: Are there inventory considerations for these substitute parts?

A: The D4GL-2AFG-A (obsolete) has 634 units in stock. The D4SL-N2AFG has 892 units available, and the D4SL-N2AFG-N has 935 units available. Both substitute parts are active products with established supply chains.
