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

Part Overview

The Omron D4GL-2BFG-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-2BFG-A4 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new installations where this legacy component specification must be met or functionally replaced.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-2BFG-A4 are identified from the Omron D4SL-N series based on the following substitution criteria:

Matching Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Locking
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Actuator Type: Panel Disconnect
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C to 55°C
• Ingress Protection: IP67 - Dust Tight, Waterproof
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Differing Parameters (Acceptable Variations):

• Product Status: D4SL-N series components are Active (vs. Obsolete D4GL)
• Current Rating: D4SL-N rated 1.5A (AC) and 220mA (DC) vs. D4GL 750mA (AC)
• Voltage Rating: D4SL-N rated 120VAC and 125VDC vs. D4GL 240VAC and 24VDC
• Holding Force: D4SL-N provides 6kgf vs. D4GL 102kgf
• Termination Style: Available in both Screw Terminal (D4SL-N2BFG) and Connector (D4SL-N2BFG-N)
• Approval Agencies: D4SL-N includes CCC, CE, cURus, TUV certifications

Two substitute part numbers are available within the D4SL-N series, differentiated by termination style.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Screw Terminal Requirement): Select D4SL-N2BFG when the application requires screw terminal connections matching the original D4GL-2BFG-A4 termination style. This substitute maintains identical panel disconnect actuator configuration and environmental protection rating (IP67).

For Connector-Based Integration: Select D4SL-N2BFG-N when system design permits connector-based termination, offering the same functional switching capability with alternative connection methodology.

Critical Considerations: The D4SL-N series substitutes operate at reduced voltage ratings (120VAC/125VDC vs. 240VAC/24VDC) and provide significantly lower holding force (6kgf vs. 102kgf). These differences must be evaluated against specific application requirements. Both substitute parts maintain Active product status with expanded regulatory approvals (CCC certification added), ensuring long-term availability and compliance support.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2BFG or D4SL-N2BFG-N directly replace D4GL-2BFG-A4 in existing installations?

A: Functional substitution is possible based on matching circuit configuration (DPST-NO/NC + DPST-NC), actuator type (Panel Disconnect), environmental rating (IP67), and operating temperature range. However, the reduced voltage rating and holding force of the D4SL-N series require application-level verification to ensure compatibility with existing electrical and mechanical requirements.

Q: What is the primary difference between D4SL-N2BFG and D4SL-N2BFG-N?

A: The termination style differs. D4SL-N2BFG uses screw terminals, matching the original D4GL-2BFG-A4 connection method. D4SL-N2BFG-N uses connector-based termination, suitable for applications where connector integration is preferred or required.

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

A: The D4SL-N and D4GL series represent different product lines within Omron's solenoid locking switch portfolio, designed for different force requirements and application classes. The 6kgf holding force of D4SL-N is appropriate for standard panel disconnect applications, while the 102kgf of D4GL addresses higher-force locking requirements.

Q: Are the D4SL-N substitutes currently available?

A: Yes. Both D4SL-N2BFG and D4SL-N2BFG-N are classified as Active products with current inventory availability (1013 and 746 units respectively), ensuring reliable sourcing compared to the obsolete D4GL-2BFG-A4.

Q: Do the substitute parts meet the same regulatory approvals as the original?

A: The D4SL-N series maintains CE and TUV certifications matching the D4GL-2BFG-A4, with additional CCC and cURus approvals. All three components meet MSL 1 (Unlimited) moisture sensitivity classification.
