Omron D4GL-1EFG-A4 Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-1EFG-A4 is a 3PST interlock solenoid locking switch designed for panel disconnect applications with 24VDC supply voltage and 240VAC rated load capacity. This component features a 102kgf holding force, screw terminal termination, and IP67 ingress protection suitable for industrial control and safety interlock systems.

The D4GL-1EFG-A4 is classified as obsolete. Equivalent substitute parts from the active D4SL-N series are available to maintain system functionality and ensure continued component availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-1EFG-A4 with active D4SL-N series components is based on the following electrical and mechanical compatibility criteria:

Preserved Parameters (Substitution Basis):

• Circuit configuration: 3PST-2NC/1NO + DPST-NO/NC (identical)
• Supply voltage: 24VDC (identical)
• Actuator type: Panel Disconnect (identical)
• Operating temperature range: -10°C ~ 55°C (identical)
• Ingress protection: IP67 (identical)
• Features: Status Indicator (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Differing Parameters (Require Application Assessment):

• Current rating: D4GL-1EFG-A4 rated 750mA AC; D4SL-N series rated 1.5A AC / 220mA DC
• Voltage rating: D4GL-1EFG-A4 rated 240VAC; D4SL-N series rated 120VAC / 125VDC
• Holding force: D4GL-1EFG-A4 provides 102kgf; D4SL-N series provides 6kgf
• Conduit thread size: D4GL-1EFG-A4 uses PG14.6; D4SL-N series uses M20
• Termination style: D4SL-N4EFG-D4 uses screw terminal; D4SL-N4EFG-D4N uses connector
• Approval agencies: D4GL-1EFG-A4 holds CE, cULus, TUV; D4SL-N series holds CCC, CE, cURus, TUV

Parameter Comparison

Engineering Selection Recommendations

For Screw Terminal Applications: The D4SL-N4EFG-D4 is the direct substitute for the D4GL-1EFG-A4 when screw terminal termination is required. Both components share identical circuit configuration, supply voltage, actuator type, operating temperature range, and ingress protection rating. The D4SL-N4EFG-D4 holds active product status with expanded approval certifications (CCC, CE, cURus, TUV) compared to the obsolete D4GL-1EFG-A4 (CE, cULus, TUV).

For Connector-Based Applications: The D4SL-N4EFG-D4N provides an alternative with connector termination instead of screw terminals. This variant maintains all functional equivalencies of the D4SL-N4EFG-D4 while offering connector-based wiring integration.

Critical Considerations: Applications requiring the 102kgf holding force of the D4GL-1EFG-A4 cannot be directly substituted with D4SL-N series components, which provide 6kgf holding force. Applications operating at 240VAC cannot use D4SL-N series components rated for 120VAC / 125VDC. Mechanical integration points using PG14.6 conduit threads must be adapted to M20 specifications.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N4EFG-D4 directly replace the D4GL-1EFG-A4 in all applications?

A: Direct substitution is possible only when the application does not depend on the 102kgf holding force of the D4GL-1EFG-A4 or the 240VAC voltage rating. The D4SL-N4EFG-D4 provides 6kgf holding force and is rated for 120VAC / 125VDC. Circuit configuration, supply voltage, operating temperature, and ingress protection are identical, supporting functional substitution in compatible load scenarios.

Q: What is the difference between D4SL-N4EFG-D4 and D4SL-N4EFG-D4N?

A: The primary difference is termination style. The D4SL-N4EFG-D4 uses screw terminal connections, while the D4SL-N4EFG-D4N uses connector-based termination. All electrical and mechanical specifications are identical. Selection depends on the wiring integration method required by the application.

Q: Are there mechanical compatibility issues when substituting the D4GL-1EFG-A4?

A: Yes. The D4GL-1EFG-A4 uses PG14.6 conduit thread size, while D4SL-N series components use M20. Mechanical mounting and conduit integration points must be adapted accordingly.

Q: What certifications do the substitute parts hold?

A: The D4SL-N4EFG-D4 and D4SL-N4EFG-D4N hold CCC, CE, cURus, and TUV certifications. The obsolete D4GL-1EFG-A4 held CE, cULus, and TUV certifications. The D4SL-N series provides expanded regulatory coverage.

Q: Is the D4SL-N series RoHS compliant?

A: Yes. The D4SL-N4EFG-D4 and D4SL-N4EFG-D4N are RoHS compliant. The D4GL-1EFG-A4 RoHS status is not specified in the available data.
