Omron D4GL-4AFA-A4 Interlock Solenoid Release DPST Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4AFA-A4 is a DPST interlock solenoid release switch designed for panel disconnect applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new installations. The D4GL-4AFA-A4 operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf, suitable for high-force industrial interlock applications. Substitute parts must maintain functional equivalence in circuit configuration, actuator type, and mechanical interface while accommodating differences in electrical ratings and termination styles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-4AFA-A4 are identified based on functional equivalence in the following critical parameters:

• Circuit configuration: DPST-NO/NC (DB/DM) x 2 (maintained across all substitutes)
• Actuator type: Panel Disconnect (maintained across all substitutes)
• Conduit thread size: M20 (maintained across all substitutes)
• Ingress protection: IP67 - Dust Tight, Waterproof (maintained across all substitutes)
• Operating temperature range: -10°C ~ 55°C (maintained across all substitutes)
• Manufacturer: Omron Automation and Safety (maintained across all substitutes)

The D4SL-N series represents the active product line replacement for the obsolete D4GL series. Both D4SL-N4AFA and D4SL-N4AFA-N maintain identical circuit, mechanical, and environmental specifications. Differences exist in electrical ratings (current and voltage) and termination style (screw terminal versus connector), which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4AFA and D4SL-N4AFA-N are active products from Omron Automation and Safety and represent the current generation replacement for the obsolete D4GL-4AFA-A4. Selection between these two substitutes depends on termination requirements:

• D4SL-N4AFA: Screw terminal configuration, suitable for direct replacement in applications currently using screw-based wiring connections
• D4SL-N4AFA-N: Connector-based termination, suitable for applications requiring quick-disconnect or modular wiring architectures

Both substitutes maintain identical mechanical interfaces (M20 conduit thread), environmental protection (IP67), and circuit functionality (DPST-NO/NC x 2). Regulatory compliance is enhanced in the D4SL-N series with additional CCC certification. Electrical rating differences (current and voltage specifications) must be verified against application load requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4AFA or D4SL-N4AFA-N be used as direct replacements for D4GL-4AFA-A4?

A: Both D4SL-N series parts maintain functional equivalence in circuit configuration, actuator type, mechanical interface, and environmental specifications. Termination style differs (screw terminal versus connector), requiring verification of wiring compatibility. Electrical ratings differ and must be confirmed against application requirements.

Q: What is the primary difference between D4SL-N4AFA and D4SL-N4AFA-N?

A: The primary difference is termination style. D4SL-N4AFA uses screw terminals, while D4SL-N4AFA-N uses connector-based termination. All other functional and mechanical parameters are identical.

Q: Are the D4SL-N substitutes compatible with existing M20 conduit installations?

A: Yes. Both D4SL-N4AFA and D4SL-N4AFA-N maintain M20 conduit thread size, ensuring mechanical compatibility with existing panel mount configurations.

Q: What certifications apply to the substitute parts?

A: D4SL-N4AFA and D4SL-N4AFA-N carry CCC, CE, cURus, and TUV certifications, providing broader regulatory coverage than the original D4GL-4AFA-A4.

Q: How do electrical ratings differ between the main part and substitutes?

A: D4GL-4AFA-A4 operates at 240VAC with 750mA AC current and 102kgf holding force. D4SL-N substitutes operate at 120VAC/125VDC with 1.5A AC or 220mA DC current and 6kgf holding force. Application electrical requirements must be verified before substitution.
