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

Part Overview

The Omron D4GL-4CFG-A is an interlock solenoid locking switch designed for panel disconnect applications with dual-pole switching capability. This component features a 24VDC supply voltage, 240VAC circuit rating, and 102kgf holding force. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for existing installations and new designs requiring similar performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-4CFG-A is based on the following critical parameters that define functional equivalence:

Mandatory Compatibility Parameters:

• Solenoid locking switch type with panel disconnect actuator
• DPST-NO/NC + DPST-NC circuit configuration
• M20 conduit thread size
• IP67 ingress protection rating
• Operating temperature range -10°C to 55°C
• Screw terminal or connector termination options

Electrical Performance Considerations: The D4GL-4CFG-A operates at 240VAC with 750mA AC current rating and 24VDC supply. The substitute parts D4SL-N4CFG and D4SL-N4CFG-N operate at 120VAC/125VDC with 1.5A AC and 220mA DC ratings. These represent different electrical specifications and are not direct functional equivalents for applications requiring 240VAC operation.

Holding Force Differential: The D4GL-4CFG-A provides 102kgf holding force, while substitute parts provide 6kgf. This significant difference restricts substitution to applications where lower holding force is acceptable.

Termination Variation: D4SL-N4CFG offers screw terminal termination matching the original part. D4SL-N4CFG-N provides connector termination as an alternative.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4CFG Selection Criteria: This part maintains screw terminal termination identical to the D4GL-4CFG-A. It is classified as active product status with current manufacturing support. Regulatory compliance includes CCC, CE, cURus, and TUV certifications, providing broader approval coverage than the obsolete original part. Selection is appropriate for applications where 120VAC operation is acceptable and holding force requirements do not exceed 6kgf.

D4SL-N4CFG-N Selection Criteria: This variant provides connector termination as an alternative to screw terminals. It shares identical electrical specifications and regulatory certifications with D4SL-N4CFG. Selection is appropriate when connector-based integration is preferred and electrical/mechanical requirements align with the D4SL-N series specifications.

Substitution Limitations: Direct functional replacement of the D4GL-4CFG-A is not possible with the D4SL-N series due to significant differences in voltage rating (240VAC vs. 120VAC), holding force (102kgf vs. 6kgf), and supply voltage specifications. Substitution is restricted to applications where these parameter differences are acceptable and do not compromise system performance or safety requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4CFG directly replace D4GL-4CFG-A in existing installations?

A: Direct replacement is not recommended without application review. The D4SL-N4CFG operates at 120VAC versus the original 240VAC rating and provides 6kgf holding force versus 102kgf. Substitution is only valid for applications where these electrical and mechanical specifications are compatible with system requirements.

Q: What is the primary difference between D4SL-N4CFG and D4SL-N4CFG-N?

A: The primary difference is termination style. D4SL-N4CFG provides screw terminal connections matching the original D4GL-4CFG-A. D4SL-N4CFG-N provides connector termination. Electrical specifications and performance characteristics are identical between both variants.

Q: Are the substitute parts actively manufactured?

A: Yes. Both D4SL-N4CFG and D4SL-N4CFG-N are classified as active products with current manufacturing support from Omron Automation and Safety. The original D4GL-4CFG-A is obsolete and no longer manufactured.

Q: What regulatory certifications apply to the substitute parts?

A: D4SL-N4CFG and D4SL-N4CFG-N carry CCC, CE, cURus, and TUV approvals. The original D4GL-4CFG-A carried CE, cULus, and TUV approvals. The substitute parts provide expanded regulatory coverage suitable for broader market applications.

Q: Can the substitute parts operate at 240VAC?

A: No. The D4SL-N series is rated for 120VAC and 125VDC operation only. Applications requiring 240VAC operation cannot use these substitute parts.

Q: What is the holding force difference and does it matter?

A: The D4GL-4CFG-A provides 102kgf holding force while D4SL-N variants provide 6kgf. This 17:1 reduction is significant. Substitution is only valid for applications where the lower holding force meets functional requirements.
