Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-4DFG-A4 are identified from the active D4SL-N series. Substitution is based on the following criteria:

Common Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Locking
• Circuit Configuration: DPST-NC x 2
• Actuator Type: Panel Disconnect
• Conduit Thread Size: M20
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67 - Dust Tight, Waterproof
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute Models:

• D4SL-N4DFG (Screw Terminal)
• D4SL-N4DFG-N (Connector Termination)

Both substitute models are active products with current availability, providing functional equivalence for panel disconnect solenoid locking applications.

Parameter Comparison

Engineering Selection Recommendations

The D4GL-4DFG-A4 is obsolete and no longer in active production. The D4SL-N series provides functional equivalence for panel disconnect solenoid locking applications with the same circuit configuration, actuator type, environmental protection rating, and operating temperature range.

Selection Criteria:

D4SL-N4DFG (Screw Terminal): Select this model when the original screw terminal connection method is required. This variant maintains compatibility with existing wiring harnesses designed for screw terminal termination.

D4SL-N4DFG-N (Connector Termination): Select this model when connector-based termination is preferred or when system redesign permits connector integration. This variant offers the same functional performance with alternative connection methodology.

Both substitute models carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part, providing enhanced compliance coverage for international applications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4DFG or D4SL-N4DFG-N directly replace D4GL-4DFG-A4?

A: Both D4SL-N models provide functional equivalence for solenoid locking panel disconnect applications. The primary difference is termination style: D4SL-N4DFG uses screw terminals matching the original part, while D4SL-N4DFG-N uses connector termination. Verify termination compatibility with your existing installation before selection.

Q: What are the key differences in electrical ratings between the main part and substitutes?

A: The D4GL-4DFG-A4 operates at 240VAC with 750mA AC current and 24VDC supply. The D4SL-N substitutes operate at 120VAC/125VDC with 1.5A AC and 220mA DC ratings. Verify that your system voltage and current requirements align with the selected substitute model.

Q: How do holding force specifications differ?

A: The D4GL-4DFG-A4 provides 102kgf holding force, while D4SL-N models provide 6kgf. Assess your mechanical load requirements to determine if the reduced holding force is acceptable for your application.

Q: Are the substitute parts available in the same packaging?

A: D4SL-N4DFG and D4SL-N4DFG-N are supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: Do the substitute models maintain the same environmental protection?

A: Yes. Both D4SL-N models maintain IP67 ingress protection (dust tight, waterproof) and the same operating temperature range (-10°C ~ 55°C) as the original part.
