Omron D4GL-4EFG-A Interlock Solenoid Locking Switch: Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4EFG-A is a 3PST interlock solenoid locking switch designed for panel disconnect applications with a 24VDC supply voltage and 240VAC rated switching capacity. This component features a 102kgf holding force, IP67 ingress protection, and screw terminal connectivity. The D4GL-4EFG-A is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration: 3PST-2NC/1NO + DPST-NO/NC
• Supply voltage: 24VDC
• Actuator type: Panel Disconnect
• Ingress protection: IP67
• Operating temperature range: -10°C to 55°C
• Approval agencies: CE, cULus/cURus, TUV

The D4SL-N series represents the active product line from Omron that maintains these core functional and environmental specifications. Two variants are available: D4SL-N4EFG-D with screw terminal connectivity and D4SL-N4EFG-DN with connector-based termination. Both variants preserve the essential switching circuit, supply voltage, actuator configuration, and environmental ratings required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4EFG-D and D4SL-N4EFG-DN are active products from Omron and carry current regulatory approvals (CCC, CE, cURus, TUV), providing compliance continuity for applications requiring the D4GL-4EFG-A.

Selection between the two D4SL-N variants depends on termination requirements:

• D4SL-N4EFG-D: Select when screw terminal connectivity matches existing wiring infrastructure and panel disconnect applications requiring direct terminal access.
• D4SL-N4EFG-DN: Select when connector-based termination is preferred for rapid assembly, maintenance, or modular system designs.

Both variants maintain identical circuit configuration, supply voltage, actuator type, ingress protection rating, and operating temperature range. The D4SL-N series exhibits reduced holding force (6kgf versus 102kgf) and lower switching voltage rating (120VAC/125VDC versus 240VAC). These parameter differences must be evaluated against specific application load and voltage requirements to confirm functional compatibility.

Frequently Asked Questions (FAQ)

Q: Why is the D4GL-4EFG-A classified as obsolete?

A: The D4GL-4EFG-A is no longer in active production. Omron has transitioned this product line to the D4SL-N series, which provides equivalent functionality with current manufacturing support and regulatory compliance.

Q: Can D4SL-N4EFG-D and D4SL-N4EFG-DN be used interchangeably?

A: Both variants share identical electrical specifications and circuit configuration. The primary difference is termination style: D4SL-N4EFG-D uses screw terminals, while D4SL-N4EFG-DN uses connector-based termination. Selection depends on the existing wiring and assembly method of your application.

Q: What are the key differences in electrical ratings between the D4GL-4EFG-A and D4SL-N substitutes?

A: The D4SL-N series supports higher AC current (1.5A versus 750mA) and adds DC current capability (220mA). However, the switching voltage rating is lower (120VAC/125VDC versus 240VAC). The holding force is also reduced (6kgf versus 102kgf). Applications operating at 240VAC or requiring 102kgf holding force must be re-evaluated for compatibility.

Q: Are both D4SL-N variants certified to the same standards as the original D4GL-4EFG-A?

A: Both D4SL-N variants carry CE, cURus, and TUV certifications, matching the original part's regulatory approvals. The D4SL-N series additionally includes CCC certification, providing broader global compliance coverage.

Q: What is the inventory status of the substitute parts?

A: D4SL-N4EFG-D has 780 pieces in stock, and D4SL-N4EFG-DN has 846 pieces in stock, both available as new original inventory from Omron.
