Omron D4GL-4AFA-A Interlock Solenoid Release DPST Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4AFA-A is an interlock solenoid release switch designed for panel disconnect applications with dual-pole, single-throw (DPST) configuration. This component operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf. The D4GL-4AFA-A is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-4AFA-A is determined by alignment across the following critical parameters:

Functional Equivalence Criteria:

• Circuit configuration: DPST-NO/NC (DB/DM) x 2
• Actuator type: Panel Disconnect
• Conduit thread size: M20
• Ingress protection: IP67
• Operating temperature range: -10°C to 55°C
• Termination compatibility with system wiring

Electrical Compatibility Considerations:

• Voltage rating and supply voltage specifications
• Current rating capacity
• Holding force requirements for the application

The D4SL-N series (D4SL-N4AFA and D4SL-N4AFA-N) maintains identical circuit configuration, actuator type, conduit thread size, ingress protection, and operating temperature range. Both substitute parts are active products from Omron Automation and Safety. The primary differences are in electrical ratings (current and voltage specifications) and termination style (screw terminal versus connector).

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4AFA (Screw Terminal Configuration)

This substitute maintains screw terminal termination identical to the D4GL-4AFA-A, supporting direct integration into existing wiring harnesses without connector adaptation. The D4SL-N4AFA is an active product with current regulatory compliance including CCC, CE, cURus, and TUV certifications. Selection of this variant is appropriate when system wiring infrastructure is designed for screw terminal connections.

D4SL-N4AFA-N (Connector Configuration)

This variant provides connector-based termination, requiring interface adaptation if the original system uses screw terminals. The D4SL-N4AFA-N is an active product with equivalent regulatory certifications. Selection is appropriate for new designs or system upgrades where connector-based termination is preferred for assembly efficiency.

Electrical Rating Considerations

Both D4SL-N substitutes operate at 120VAC/125VDC with 1.5A AC and 220mA DC current ratings, differing from the D4GL-4AFA-A specification of 240VAC with 750mA AC. The D4SL-N series holding force is 6kgf compared to 102kgf for the original part. System design must confirm that the substitute electrical ratings and holding force are compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4AFA or D4SL-N4AFA-N directly replace D4GL-4AFA-A in existing installations?

A: Both D4SL-N variants maintain identical circuit configuration (DPST-NO/NC x 2), actuator type (Panel Disconnect), conduit thread size (M20), ingress protection (IP67), and operating temperature range (-10°C to 55°C). However, electrical specifications differ: the D4SL-N series operates at 120VAC/125VDC versus the D4GL-4AFA-A at 240VAC, and current ratings are 1.5A AC/220mA DC versus 750mA AC. Holding force differs significantly (6kgf versus 102kgf). Substitution requires confirmation that the application can operate within the D4SL-N electrical parameters and holding force specification.

Q: What is the difference between D4SL-N4AFA and D4SL-N4AFA-N?

A: The primary difference is termination style. D4SL-N4AFA uses screw terminal connections, while D4SL-N4AFA-N uses connector-based termination. All other electrical and mechanical specifications are identical. Selection depends on the wiring interface requirements of the target system.

Q: Are both substitute parts currently available?

A: Yes. Both D4SL-N4AFA and D4SL-N4AFA-N are active products from Omron Automation and Safety. The D4GL-4AFA-A is obsolete, making these active alternatives the appropriate selection path for replacement or new implementations.

Q: Do the substitute parts have equivalent regulatory certifications?

A: Both D4SL-N variants carry CCC, CE, cURus, and TUV certifications, providing broader regulatory coverage than the original D4GL-4AFA-A (CE, cULus, TUV). Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What mechanical compatibility exists between the original and substitute parts?

A: All three parts share M20 conduit thread size, IP67 ingress protection, and -10°C to 55°C operating temperature range, supporting mechanical interchangeability in panel mount applications. Termination style differences (screw terminal versus connector) may require wiring interface adaptation.
