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

Part Overview

The Omron D4GL-2GFG-A is a 3PST interlock solenoid locking switch designed for panel disconnect applications with a 24VDC supply voltage and 240VAC load rating. This component is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system maintenance and new design implementations. The D4GL series has been superseded by the D4SL-N series, which maintains core functional compatibility while offering active product status and expanded availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2GFG-A is determined by the following critical parameters:

Functional Equivalence Criteria:

• Circuit configuration: 3PST-NC + DPST-NO/NC (must match exactly)
• Supply voltage: 24VDC (must match)
• Actuator type: Panel Disconnect (must match)
• Ingress protection: IP67 minimum (must match or exceed)
• Operating temperature range: -10°C ~ 55°C (must encompass or match)
• Approval agencies: CE, cULus, TUV (must include or exceed)

Acceptable Variation Parameters:

• Load voltage rating: Substitute may support different load voltages if application requirements permit
• Load current rating: Substitute may have different current capacity if application load is within substitute rating
• Holding force: Substitute may differ if mechanical requirements are satisfied
• Termination style: Screw Terminal or Connector acceptable based on installation method
• Packaging: Bulk or standard packaging acceptable

The D4SL-N2GFG-D and D4SL-N2GFG-DN are direct functional equivalents from the active D4SL-N series, maintaining identical circuit configuration, supply voltage, actuator type, and environmental specifications while offering improved product availability and active manufacturer support.

Engineering Selection Recommendations

D4SL-N2GFG-D (Screw Terminal Configuration)

This substitute is recommended for applications requiring screw terminal connections. The D4SL-N2GFG-D maintains active product status with Omron, ensuring long-term availability and manufacturer support. Load voltage and current specifications (120VAC, 125VDC, 1.5A AC, 220mA DC) are suitable for applications where the original 240VAC, 750mA rating is not a strict requirement. The reduced holding force (6kgf versus 102kgf) must be evaluated against specific mechanical locking requirements. Approval certifications include CCC, CE, cURus, and TUV, providing expanded compliance coverage.

D4SL-N2GFG-DN (Connector Configuration)

This substitute is recommended for applications requiring connector-based termination. Electrical and mechanical specifications are identical to the D4SL-N2GFG-D. The connector termination style eliminates screw terminal assembly requirements, reducing installation time and potential connection errors. This variant is suitable for applications where connector-based integration is preferred or mandated by system design.

Selection Criteria:

Choose D4SL-N2GFG-D if screw terminal connections are required or preferred. Choose D4SL-N2GFG-DN if connector-based termination aligns with system architecture. Both variants provide equivalent functional performance for panel disconnect solenoid locking applications with 24VDC supply voltage and IP67 environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2GFG-D or D4SL-N2GFG-DN directly replace the D4GL-2GFG-A in existing installations?

A: Direct replacement is possible if the application load voltage and current requirements fall within the D4SL-N specifications (120VAC, 125VDC, 1.5A AC, 220mA DC). The circuit configuration, supply voltage, actuator type, and environmental specifications are identical. If the original application requires 240VAC or 750mA load capacity, the D4SL-N variants may not be suitable.

Q: What is the primary difference between D4SL-N2GFG-D and D4SL-N2GFG-DN?

A: The termination style differs. D4SL-N2GFG-D uses screw terminals for wire connection, while D4SL-N2GFG-DN uses a connector interface. Electrical and mechanical performance are identical. Selection depends on installation method and system integration requirements.

Q: Why does the D4SL-N series have lower holding force (6kgf) compared to the D4GL-2GFG-A (102kgf)?

A: The D4SL-N series represents a different product line within Omron's solenoid locking portfolio. The reduced holding force reflects design optimization for different application classes. Verify that the 6kgf holding force is sufficient for the intended mechanical locking requirement before substitution.

Q: Are the D4SL-N variants available in the same packaging as the D4GL-2GFG-A?

A: The D4SL-N variants are supplied in bulk packaging. The original D4GL-2GFG-A packaging specification was not provided in the technical data. Confirm packaging requirements with procurement or system integration specifications.

Q: Do the D4SL-N variants support the same approval certifications as the D4GL-2GFG-A?

A: The D4SL-N variants support CE, cURus, and TUV certifications, which overlap with the original D4GL-2GFG-A (CE, cULus, TUV). The D4SL-N series adds CCC certification. Confirm that the certification set meets regulatory requirements for the target application region.

Q: What is the inventory status of these substitute parts?

A: D4SL-N2GFG-D has 699 units in stock. D4SL-N2GFG-DN has 982 units in stock. Both are active products with ongoing manufacturer support, ensuring continued availability for future procurement.
