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

Part Overview

The Omron D4GL-1EFA-A is a 3PST interlock solenoid release switch designed for panel disconnect applications with 24VDC supply voltage and 240VAC rated switching capacity. This component features a solenoid release mechanism with status indicator, screw terminal connections, and IP67 ingress protection suitable for industrial control environments.

The D4GL-1EFA-A is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-1EFA-A are identified from the Omron D4SL-N series based on the following substitution criteria:

Matching Parameters:

• Identical circuit configuration: 3PST-2NC/1NO + DPST-NO/NC
• Identical supply voltage: 24VDC
• Identical actuator type: Panel Disconnect
• Identical features: Status Indicator
• Identical operating temperature range: -10°C ~ 55°C
• Identical ingress protection: IP67
• Identical moisture sensitivity level: 1 (Unlimited)
• Same manufacturer: Omron Automation and Safety

Differing Parameters:

• Substitute parts feature active product status versus obsolete
• Substitute parts support dual voltage ratings (120VAC, 125VDC) versus single 240VAC rating
• Substitute parts have reduced holding force (6kgf versus 102kgf)
• Substitute parts use M20 conduit thread versus PG14.6
• Substitute parts offer termination options: screw terminal or connector

The D4SL-N series represents the active replacement line for the obsolete D4GL series within Omron's interlock solenoid release portfolio.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4EFA-D (Screw Terminal Configuration)

This substitute is suitable for applications requiring direct replacement with screw terminal connections. The part maintains identical circuit topology, supply voltage, and environmental specifications. Active product status ensures ongoing manufacturer support and availability. Compliance certifications include CCC, CE, cURus, and TUV, providing broader regulatory coverage than the original D4GL-1EFA-A.

D4SL-N4EFA-DN (Connector Configuration)

This substitute provides identical functional and environmental specifications with connector-based termination. Selection of this variant depends on system integration requirements and whether connector-based connections are compatible with existing wiring infrastructure.

Voltage Rating Consideration

Both substitute parts support 120VAC and 125VDC switching ratings, differing from the original 240VAC specification. Applications requiring 240VAC switching capacity must evaluate whether the substitute voltage ratings are compatible with system requirements.

Holding Force Consideration

Substitute parts provide 6kgf holding force compared to the original 102kgf specification. Applications dependent on the higher holding force must assess whether reduced force is acceptable for the intended function.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4EFA-D or D4SL-N4EFA-DN directly replace D4GL-1EFA-A in existing installations?

A: Both D4SL-N series parts maintain identical circuit configuration, supply voltage (24VDC), actuator type, and environmental specifications (IP67, operating temperature, MSL). Compatibility depends on two factors: (1) whether the application requires 240VAC switching capacity, as substitutes support 120VAC/125VDC; and (2) whether the reduced holding force (6kgf versus 102kgf) is acceptable for the application. Termination style differs between screw terminal (D4SL-N4EFA-D) and connector (D4SL-N4EFA-DN).

Q: What is the primary difference between D4SL-N4EFA-D and D4SL-N4EFA-DN?

A: The primary difference is termination style. D4SL-N4EFA-D uses screw terminals, while D4SL-N4EFA-DN uses connector-based termination. All other electrical and mechanical specifications are identical. Selection depends on whether the installation uses screw terminal or connector-based wiring infrastructure.

Q: Why do the substitute parts have lower holding force than the original?

A: The D4SL-N series represents a different product line within Omron's solenoid release portfolio, designed for different application requirements. The 6kgf holding force of the D4SL-N series is suitable for standard panel disconnect applications, while the original D4GL-1EFA-A with 102kgf was designed for higher-force applications. Application requirements determine whether the substitute holding force is acceptable.

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

A: Both substitute parts are supplied in bulk packaging, differing from the original part's packaging specification. Inventory availability for both D4SL-N4EFA-D and D4SL-N4EFA-DN is confirmed at 691 and 726 units respectively.

Q: What regulatory certifications do the substitute parts carry?

A: D4SL-N4EFA-D and D4SL-N4EFA-DN carry CCC, CE, cURus, and TUV certifications. The original D4GL-1EFA-A carried CE, cULus, and TUV certifications. The substitute parts provide additional CCC certification and cURus (versus cULus) certification, potentially offering broader regulatory compliance for certain markets.
