Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-2BFA-A4 is based on the following critical parameters:

Functional Compatibility Criteria:

• Type: Solenoid Release
• Actuator Type: Panel Disconnect
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Manufacturer: Omron Automation and Safety

Electrical Parameter Considerations: The D4GL-2BFA-A4 operates at 240VAC with 750mA AC current and 24VDC supply. Substitute parts must maintain compatible voltage and current ratings within the same operational envelope.

Mechanical Parameter Considerations: The D4GL-2BFA-A4 provides 102kgf holding force. Substitute parts with reduced holding force (6kgf) represent a significant mechanical downgrade and are suitable only for applications where lower holding force is acceptable.

Termination Compatibility: The D4GL-2BFA-A4 uses screw terminal connections. Substitute parts with connector termination require integration modifications.

The D4SL-N2BFA and D4SL-N2BFA-N are active Omron solenoid release switches that share the same circuit configuration, actuator type, thread size, temperature range, and ingress protection rating. Both parts are manufactured by Omron and carry equivalent regulatory approvals.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2BFA (Screw Terminal Configuration)

The D4SL-N2BFA is an active product with direct termination compatibility to the D4GL-2BFA-A4. Both parts feature screw terminal connections, eliminating integration modifications. The D4SL-N2BFA carries expanded regulatory approvals including CCC certification. The primary electrical difference is reduced holding force (6kgf versus 102kgf), which is acceptable only in applications where lower clamping force meets functional requirements. The D4SL-N2BFA supports higher AC current capacity (1.5A versus 750mA) and operates at lower voltage ratings (120VAC/125VDC versus 240VAC/24VDC).

D4SL-N2BFA-N (Connector Termination Configuration)

The D4SL-N2BFA-N is functionally equivalent to the D4SL-N2BFA with connector termination instead of screw terminals. This configuration requires integration modifications to existing screw terminal wiring. Selection of this variant is appropriate only when connector termination is preferred or when existing system architecture supports connector-based connections. Electrical and mechanical specifications are identical to the D4SL-N2BFA.

Product Status Consideration

Both substitute parts are active products with current manufacturing support and inventory availability, providing supply chain continuity for the obsolete D4GL-2BFA-A4.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2BFA directly replace the D4GL-2BFA-A4 in existing installations?

A: Direct replacement is possible from a functional and mechanical standpoint. Both parts share identical circuit configuration, actuator type, thread size, temperature range, and ingress protection rating. However, the D4SL-N2BFA operates at different voltage ratings (120VAC/125VDC versus 240VAC/24VDC) and provides significantly lower holding force (6kgf versus 102kgf). Electrical system compatibility and force requirement verification are necessary before installation.

Q: What is the primary difference between D4SL-N2BFA and D4SL-N2BFA-N?

A: The D4SL-N2BFA uses screw terminal connections, while the D4SL-N2BFA-N uses connector termination. All other electrical and mechanical specifications are identical. Selection depends on existing wiring infrastructure and integration requirements.

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

A: The D4GL and D4SL series represent different product lines within Omron's solenoid release portfolio, designed for different force requirements. The D4GL-2BFA-A4 is engineered for high-force applications (102kgf), while the D4SL-N series addresses standard-force applications (6kgf). Application force requirements determine which series is appropriate.

Q: Are the substitute parts certified for the same regulatory standards?

A: The D4GL-2BFA-A4 carries CE, cULus, and TUV approvals. The D4SL-N2BFA and D4SL-N2BFA-N carry CCC, CE, cURus, and TUV approvals. Both substitute parts meet or exceed the regulatory requirements of the original part. Regional compliance requirements should be verified based on intended application geography.

Q: What is the current rating difference between the original and substitute parts?

A: The D4GL-2BFA-A4 is rated for 750mA AC at 240VAC. The D4SL-N2BFA and D4SL-N2BFA-N are rated for 1.5A AC at 120VAC and 220mA DC at 125VDC. The substitute parts support higher AC current capacity but operate at lower voltage levels. Load current and voltage requirements must be verified for compatibility.
