Omron D4GL-4AFG-A4 Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4AFG-A4 is an interlock solenoid locking switch designed for panel disconnect applications with dual-pole, single-throw configuration. This component features a 24VDC supply voltage, 240VAC switching capability, and 102kgf holding force. The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain system functionality and ensure continued availability for replacement and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-4AFG-A4 are identified from the Omron D4SL-N series based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Locking
• Circuit Configuration: DPST-NO/NC (DB/DM) x 2
• Actuator Type: Panel Disconnect
• Conduit Thread Size: M20
• Operating Temperature Range: -10°C to 55°C
• Ingress Protection: IP67 - Dust Tight, Waterproof
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameters: The D4SL-N series substitutes operate at different voltage and current ratings (120VAC/125VDC with 1.5A AC and 220mA DC capability) compared to the original 240VAC/24VDC specification. The holding force is reduced to 6kgf. Termination style varies between screw terminal and connector options. These differences require engineering evaluation for specific application requirements.

Engineering Selection Recommendations

D4SL-N4AFG (Screw Terminal): This active substitute maintains the screw terminal configuration of the original D4GL-4AFG-A4. It carries expanded regulatory approvals including CCC certification in addition to CE, cURus, and TUV. Current inventory of 2200 units supports immediate availability. Selection of this variant is appropriate when screw terminal termination is required for existing wiring infrastructure.

D4SL-N4AFG-N (Connector Termination): This variant provides connector-based termination instead of screw terminals. It shares identical electrical and mechanical specifications with the D4SL-N4AFG and carries the same regulatory certifications. Inventory of 726 units is available. This option is suitable for applications where connector-based connections are preferred or required.

Both D4SL-N series substitutes are active products with current manufacturing support and regulatory compliance documentation. Selection between the two variants depends solely on termination style requirements for the specific installation.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N series directly replace the obsolete D4GL-4AFG-A4?

A: The D4SL-N series maintains functional equivalence in circuit configuration, actuator type, mechanical dimensions (M20 conduit thread), operating temperature range, and ingress protection rating. However, voltage and current ratings differ significantly. The D4GL-4AFG-A4 operates at 240VAC/24VDC with 750mA AC current, while D4SL-N variants operate at 120VAC/125VDC with 1.5A AC and 220mA DC capability. Holding force is reduced from 102kgf to 6kgf. Application-specific electrical requirements must be evaluated before substitution.

Q: What is the difference between D4SL-N4AFG and D4SL-N4AFG-N?

A: The primary difference is termination style. The D4SL-N4AFG uses screw terminals, while the D4SL-N4AFG-N uses connector termination. All other electrical, mechanical, and regulatory specifications are identical. Selection depends on the connection method required for your installation.

Q: Are both substitute parts currently available?

A: Yes. The D4SL-N4AFG has 2200 units in stock, and the D4SL-N4AFG-N has 726 units in stock. Both are classified as active products with ongoing manufacturing support.

Q: What regulatory certifications apply to the substitute parts?

A: Both D4SL-N variants carry CCC, CE, cURus, and TUV approvals. The original D4GL-4AFG-A4 carried CE, cULus, and TUV certifications. The expanded certification portfolio of the substitutes provides broader regional compliance coverage.

Q: Does the reduced holding force of the D4SL-N series affect compatibility?

A: The D4SL-N series provides 6kgf holding force compared to 102kgf for the D4GL-4AFG-A4. This represents a significant reduction and must be evaluated against the mechanical load requirements of the specific application. Applications requiring the original 102kgf holding force cannot use these substitutes.
