Omron D4GL-2AFG-A4 Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2AFG-A4 is an interlock solenoid locking switch classified as a DPST (Double Pole Single Throw) device with dual NO/NC circuits. This component functions as a panel disconnect actuator with a holding force of 102kgf, designed for 240VAC operation with 24VDC supply voltage. The product is currently obsolete, necessitating identification of functionally equivalent active alternatives from the same manufacturer to maintain system compatibility and ensure continued availability for maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-2AFG-A4 is based on the following critical parameters that must align across alternatives:

Mandatory 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: G1/2
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Product Status: Active (required for current availability)

Allowable Variations:

• Voltage Rating and Supply Voltage: The D4SL-N series operates at 120VAC/125VDC instead of 240VAC/24VDC, representing a different electrical specification tier
• Current Rating: D4SL-N series rated at 1.5A (AC) and 220mA (DC) versus 750mA (AC) on the original
• Holding Force: D4SL-N series provides 6kgf versus 102kgf on the original
• Termination Style: Available in both Screw Terminal (D4SL-N2AFG) and Connector (D4SL-N2AFG-N) options
• Approval Agencies: D4SL-N series includes CCC, CE, cURus, TUV certifications

The D4SL-N2AFG and D4SL-N2AFG-N are active product alternatives within the Omron solenoid locking switch portfolio that maintain core functional characteristics while differing in electrical ratings and termination interfaces.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2AFG (Screw Terminal Configuration): This substitute maintains screw terminal termination identical to the original D4GL-2AFG-A4, facilitating direct wiring compatibility in existing installations. The part is active and carries CE, cURus, and TUV certifications, ensuring regulatory compliance across major markets. Selection of this variant is appropriate when existing wiring harnesses and terminal connections are designed for screw-based termination.

D4SL-N2AFG-N (Connector Configuration): This variant provides connector-based termination, offering advantages in applications requiring rapid disconnect and reconnect cycles. The part maintains active product status with equivalent regulatory certifications. Selection is appropriate for new designs or retrofit applications where connector-based interfaces are preferred for maintenance accessibility.

Critical Consideration: Both D4SL-N series alternatives operate at reduced voltage ratings (120VAC/125VDC) and lower holding force (6kgf) compared to the original D4GL-2AFG-A4 (240VAC/24VDC, 102kgf). Application compatibility must be verified against actual system voltage and force requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2AFG directly replace the D4GL-2AFG-A4 in existing installations?

A: Direct replacement requires verification of system voltage compatibility. The D4GL-2AFG-A4 operates at 240VAC with 24VDC supply, while the D4SL-N2AFG operates at 120VAC with 125VDC supply. If the installation uses 240VAC/24VDC, the D4SL-N series is not electrically compatible without system modification. If the installation uses 120VAC/125VDC, compatibility is confirmed for the core switching function.

Q: What is the difference between D4SL-N2AFG and D4SL-N2AFG-N?

A: The primary difference is termination style. The D4SL-N2AFG uses screw terminals for direct wire connection, while the D4SL-N2AFG-N uses a connector interface. Both maintain identical electrical ratings, circuit configuration, and mechanical specifications. Selection depends on the termination interface required by the application.

Q: Why does the D4SL-N series have lower holding force than the D4GL-2AFG-A4?

A: The D4SL-N series (6kgf holding force) and D4GL series (102kgf holding force) represent different product lines within Omron's solenoid locking switch portfolio, each designed for specific force requirements. The D4SL-N is suitable for applications requiring moderate holding force, while the D4GL was designed for higher-force applications. Application requirements must determine which force rating is appropriate.

Q: Are the D4SL-N2AFG and D4SL-N2AFG-N certified for the same regulatory standards?

A: Both variants carry identical certifications: CCC, CE, cURus, and TUV. Both maintain IP67 ingress protection and MSL 1 moisture sensitivity rating. Regulatory compliance is equivalent between the two termination styles.

Q: What inventory status applies to these substitute parts?

A: The D4SL-N2AFG has 892 pieces in stock, and the D4SL-N2AFG-N has 935 pieces in stock, both listed as new original inventory. Both parts maintain active product status with Omron, ensuring continued availability and support.
