Omron D4GL-1AFG-A Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-1AFG-A is an interlock solenoid locking switch designed for panel disconnect applications with dual-pole, single-throw configuration. This component is classified as obsolete, making identification of active equivalent parts essential for system maintenance and new design implementations. The D4GL series has been superseded by the D4SL-N series, which maintains functional compatibility while offering enhanced availability and active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-1AFG-A is determined by the following critical parameters:

Functional Compatibility Criteria:

• Circuit configuration: DPST-NO/NC (DB/DM) x 2
• Actuator type: Panel Disconnect
• Ingress protection: IP67 minimum
• Operating temperature range: -10°C to 55°C minimum
• Solenoid locking mechanism

Electrical Compatibility Criteria:

• AC current rating capability
• Voltage rating compatibility
• Termination style (screw terminal or connector)

The D4SL-N series substitutes meet the core functional requirements of the D4GL-1AFG-A while providing active product status and improved availability. Both substitute parts maintain the same circuit configuration, actuator type, ingress protection rating, and operating temperature range. Differences in electrical ratings and holding force are documented in the parameter comparison table below.

Engineering Selection Recommendations

For D4GL-1AFG-A Replacement:

The D4SL-N4AFG and D4SL-N4AFG-N are the designated active equivalents for the obsolete D4GL-1AFG-A. Both parts maintain functional compatibility through identical circuit configuration, actuator type, ingress protection rating, and operating temperature range.

D4SL-N4AFG Selection Criteria:

• Screw terminal termination matches the original D4GL-1AFG-A
• Active product status with full manufacturer support
• Expanded approval certifications (CCC, CE, cURus, TUV)
• Suitable for direct replacement in existing screw terminal installations

D4SL-N4AFG-N Selection Criteria:

• Connector termination provides alternative integration method
• Active product status with full manufacturer support
• Expanded approval certifications (CCC, CE, cURus, TUV)
• Suitable for applications requiring connector-based termination

Electrical Rating Considerations: The D4SL-N series operates at lower voltage ratings (120VAC, 125VDC) compared to the D4GL-1AFG-A (240VAC). Verify that system voltage requirements align with the substitute part specifications before implementation. The D4SL-N series provides higher AC current capacity (1.5A versus 750mA), which accommodates broader application requirements.

Mechanical Considerations: The D4SL-N series uses M20 conduit thread size versus PG14.6 on the original part. Conduit adapter compatibility must be evaluated for existing installations.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N4AFG directly replace the D4GL-1AFG-A in existing installations?

A: The D4SL-N4AFG maintains functional compatibility through identical circuit configuration, actuator type, and ingress protection rating. However, the conduit thread size differs (M20 versus PG14.6), requiring adapter evaluation. Electrical ratings also differ; verify that 120VAC/125VDC operation aligns with system requirements.

Q: What is the difference between D4SL-N4AFG and D4SL-N4AFG-N?

A: Both parts are functionally identical with the same electrical ratings, circuit configuration, and performance specifications. The primary difference is termination style: D4SL-N4AFG uses screw terminals, while D4SL-N4AFG-N uses connector termination. Select based on your installation's termination requirements.

Q: Why does the D4SL-N series have lower voltage ratings than the D4GL-1AFG-A?

A: The D4SL-N series is designed for different voltage applications (120VAC/125VDC) compared to the D4GL-1AFG-A (240VAC). These represent distinct product lines within Omron's solenoid locking switch portfolio. Confirm your system voltage requirements before selecting a substitute.

Q: Is the holding force difference between D4GL-1AFG-A (102kgf) and D4SL-N series (6kgf) significant?

A: The holding force specifications reflect different design parameters for each series. The D4SL-N series is engineered for applications requiring 6kgf holding force. If your application requires 102kgf holding force, the D4SL-N series may not be suitable; consult Omron for alternative solutions.

Q: What certifications apply to the D4SL-N substitute parts?

A: The D4SL-N4AFG and D4SL-N4AFG-N carry CCC, CE, cURus, and TUV certifications. The original D4GL-1AFG-A carried CE, cULus, and TUV certifications. The expanded certification scope of the D4SL-N series provides broader regulatory compliance coverage.

Q: Are there packaging differences between the substitute parts?

A: Both D4SL-N4AFG and D4SL-N4AFG-N are supplied in bulk packaging. The original D4GL-1AFG-A packaging specification was not provided in the technical data.
