Omron D4GL-1DFA-A Interlock Solenoid Release: Equivalent & Substitute Parts

Part Overview

The Omron D4GL-1DFA-A is a DPST interlock solenoid release switch designed for panel disconnect applications. This component operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf. The D4GL-1DFA-A is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-1DFA-A requires matching the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Release
• Circuit Configuration: DPST-NC x 2
• Actuator Type: Panel Disconnect
• Ingress Protection: IP67
• Operating Temperature Range: -10°C to 55°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variations:

• Current Rating: The D4GL-1DFA-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-1DFA-A operates at 240VAC with 24VDC supply. Substitute parts with different voltage ratings (120VAC, 125VDC) represent different application configurations and are listed as alternatives for systems with different electrical specifications.
• Holding Force: The D4GL-1DFA-A provides 102kgf. Substitute parts with lower holding force (6kgf) are not equivalent for high-force applications but may serve lower-force requirements.
• Termination Style: Screw Terminal vs. Connector variations exist among substitutes.
• Conduit Thread Size: PG14.6 vs. M20 represent different mechanical interfaces.

The D4SL-N series (D4SL-N4DFA and D4SL-N4DFA-N) are active products from Omron that maintain the core solenoid release functionality and DPST-NC circuit configuration required for panel disconnect applications.

Parameter Comparison

Engineering Selection Recommendations

For D4GL-1DFA-A Replacement:

The D4SL-N4DFA and D4SL-N4DFA-N are active Omron products that maintain functional equivalence for panel disconnect solenoid release applications. Both parts preserve the DPST-NC x 2 circuit configuration, IP67 ingress protection, and operating temperature range of the original component.

D4SL-N4DFA Selection Criteria:

• Screw terminal termination matches the original D4GL-1DFA-A interface
• M20 conduit thread size requires mechanical interface adaptation from PG14.6
• 120VAC/125VDC voltage rating applies to systems with different electrical specifications than the original 240VAC/24VDC configuration
• Higher AC current rating (1.5A) provides increased capacity margin
• Active product status ensures ongoing availability and support

D4SL-N4DFA-N Selection Criteria:

• Connector termination provides an alternative to screw terminal interface
• M20 conduit thread size requires mechanical interface adaptation from PG14.6
• 120VAC/125VDC voltage rating applies to systems with different electrical specifications than the original 240VAC/24VDC configuration
• Higher AC current rating (1.5A) provides increased capacity margin
• Active product status ensures ongoing availability and support

Both D4SL-N series alternatives carry expanded approval certifications (CCC, CE, cURus, TUV) compared to the original part, supporting broader regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N4DFA directly replace the D4GL-1DFA-A without modifications?

A: The D4SL-N4DFA maintains the same solenoid release type, DPST-NC x 2 circuit configuration, and panel disconnect actuator function. However, mechanical interface differences exist: the conduit thread size changes from PG14.6 to M20, and the voltage rating differs (120VAC/125VDC vs. 240VAC/24VDC). System integration requires evaluation of these parameters against your application requirements.

Q: What is the difference between D4SL-N4DFA and D4SL-N4DFA-N?

A: The primary difference is termination style. The D4SL-N4DFA uses screw terminals, matching the original D4GL-1DFA-A interface. The D4SL-N4DFA-N uses connector termination. Both maintain identical electrical specifications, circuit configuration, and mechanical mounting characteristics.

Q: Why does the D4SL-N series have lower holding force (6kgf) compared to the D4GL-1DFA-A (102kgf)?

A: The D4SL-N series represents a different product line within the Omron solenoid release portfolio. The holding force difference reflects distinct design specifications for different application classes. Selection between these products must be based on your specific force requirements.

Q: Are the D4SL-N4DFA and D4SL-N4DFA-N suitable for the same voltage systems as the D4GL-1DFA-A?

A: No. The D4GL-1DFA-A operates at 240VAC with 24VDC supply. The D4SL-N series operates at 120VAC with 125VDC supply. These represent different electrical specifications and are not interchangeable in systems designed for the original voltage ratings without additional power conversion or system redesign.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N4DFA and D4SL-N4DFA-N carry CCC, CE, cURus, and TUV approvals. The original D4GL-1DFA-A carried CE, cULus, and TUV approvals. The expanded certification set of the substitute parts supports broader regulatory compliance in additional markets.

Q: Is the D4SL-N series actively manufactured?

A: Yes. Both D4SL-N4DFA and D4SL-N4DFA-N are classified as active products, ensuring ongoing manufacturing, availability, and technical support from Omron Automation and Safety.
