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

Part Overview

The Omron D4GL-2CFG-A4 is an interlock solenoid locking switch designed for panel disconnect applications with dual-pole switching capability (DPST-NO/NC + DPST-NC). This component operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf, suitable for industrial safety and access control systems requiring positive locking mechanisms.

The D4GL-2CFG-A4 has reached obsolete product status. Locating active equivalent models is necessary to ensure continued supply chain availability, ongoing technical support, and compliance with current manufacturing standards. Two active substitute models from the Omron D4SL-N series are available as direct replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4GL-2CFG-A4 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Solenoid locking switch type with panel disconnect actuator
• DPST-NO/NC + DPST-NC circuit configuration
• Screw terminal or connector termination (both acceptable for electrical function)
• G1/2 conduit thread size
• IP67 ingress protection rating
• Operating temperature range of -10°C to 55°C or broader
• Approval certifications including CE and TUV

Acceptable Parameter Variations:

• Current rating: The D4SL-N series supports 1.5A AC and 220mA DC, which accommodates the original 750mA AC requirement
• Voltage rating: The D4SL-N series operates at 120VAC and 125VDC, representing a different voltage class suitable for alternative supply configurations
• Holding force: The D4SL-N series provides 6kgf, which is lower than the original 102kgf and must be evaluated against specific application requirements
• Termination style: Both screw terminal and connector options are functionally equivalent for electrical connection purposes

The D4SL-N2CFG and D4SL-N2CFG-N models meet all mandatory criteria and are classified as active products with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2CFG (Screw Terminal Configuration)

This model is the direct functional equivalent for applications requiring screw terminal connections. It maintains identical circuit configuration, operating temperature range, ingress protection, and conduit thread specifications. The model is actively manufactured with current technical support and expanded approval certifications (CCC addition). Selection is appropriate for new designs and direct replacement scenarios where screw terminal termination is specified.

D4SL-N2CFG-N (Connector Configuration)

This model provides identical electrical and mechanical specifications to the D4SL-N2CFG with connector-based termination. Selection is appropriate for applications where connector-based assembly and field replacement procedures are preferred. Both D4SL-N variants carry equivalent active product status and compliance certifications.

Critical Design Consideration

The D4SL-N series provides a holding force of 6kgf compared to the original 102kgf specification. Applications requiring the original holding force specification must conduct mechanical load analysis to determine if the reduced force is acceptable for the intended use case. This parameter difference represents the primary technical distinction between the obsolete and active models.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2CFG directly replace the D4GL-2CFG-A4 in existing installations?

A: Both models share identical circuit configuration (DPST-NO/NC + DPST-NC), operating temperature range (-10°C to 55°C), ingress protection (IP67), and conduit thread size (G1/2). The primary difference is holding force (6kgf versus 102kgf). Direct replacement is mechanically and electrically feasible if the application does not require the original holding force specification.

Q: What is the difference between D4SL-N2CFG and D4SL-N2CFG-N?

A: Both models are electrically and mechanically identical. The sole difference is termination style: D4SL-N2CFG uses screw terminals, while D4SL-N2CFG-N uses connector termination. Selection depends on installation and maintenance procedures specified for your application.

Q: Are the D4SL-N models approved for the same regulatory environments as the D4GL-2CFG-A4?

A: The D4SL-N series carries CE and TUV certifications matching the original model, with the addition of CCC and cURus approvals. Both models meet the same core regulatory requirements for industrial safety applications.

Q: What voltage configurations are available with the D4SL-N substitute models?

A: The D4SL-N series operates at 120VAC and 125VDC, differing from the original 240VAC specification. Applications requiring 240VAC operation must evaluate whether the available voltage ratings are compatible with system design parameters.

Q: Is the D4GL-2CFG-A4 still available for purchase?

A: The D4GL-2CFG-A4 is classified as obsolete. Current inventory may exist through authorized distributors, but long-term supply is not guaranteed. The D4SL-N2CFG and D4SL-N2CFG-N models are active products with ongoing manufacturing support and are recommended for new procurements.
