Omron D4GL-1EFG-A Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-1EFG-A is an interlock solenoid locking switch designed for panel disconnect applications with 3PST circuit configuration and dual-stage switching capability (3PST-2NC/1NO + DPST-NO/NC). This component operates at 24VDC supply voltage with 240VAC rated load switching capacity at 750mA AC current. The unit features IP67 ingress protection, status indicator functionality, and screw terminal connections.

The D4GL-1EFG-A carries an obsolete product status. Equivalent substitute parts from the active D4SL-N series are available to maintain system functionality and ensure continued component availability for new designs and field replacements.

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-1EFG-A is based on functional equivalence within the Omron interlock solenoid locking switch product family. The active D4SL-N series provides direct functional replacement with the following alignment criteria:

Preserved Parameters (Substitution Basis):

• Type: Solenoid Locking
• Circuit Configuration: 3PST-2NC/1NO + DPST-NO/NC
• Voltage Supply: 24VDC
• Actuator Type: Panel Disconnect
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Features: Status Indicator
• Approval Agencies: CE, TUV (common to both)

Differing Parameters (Application-Dependent):

• Current Rating: D4SL-N series rated 1.5A (AC), 220mA (DC) versus D4GL-1EFG-A at 750mA (AC)
• Voltage Rating: D4SL-N series rated 120VAC, 125VDC versus D4GL-1EFG-A at 240VAC
• Holding Force: D4SL-N series 6kgf versus D4GL-1EFG-A at 102kgf
• Conduit Thread Size: D4SL-N series M20 versus D4GL-1EFG-A at PG14.6
• Termination Style: D4SL-N4EFG-D uses Screw Terminal; D4SL-N4EFG-DN uses Connector

Two substitute options are provided: D4SL-N4EFG-D (screw terminal) and D4SL-N4EFG-DN (connector termination).

Parameter Comparison

Engineering Selection Recommendations

For Screw Terminal Applications: Select D4SL-N4EFG-D when the original D4GL-1EFG-A screw terminal connection method must be maintained. This substitute is active in production and carries expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the obsolete original part.

For Connector-Based Applications: Select D4SL-N4EFG-DN when connector termination is preferred or required by system design. This part provides identical functional performance to D4SL-N4EFG-D with connector-style termination.

Load Compatibility Verification: The D4SL-N series is rated for 120VAC load voltage and 1.5A AC current, which differs from the D4GL-1EFG-A specification of 240VAC at 750mA. Applications requiring 240VAC load switching or higher current capacity must be evaluated against the reduced ratings of the D4SL-N series. The D4SL-N series holding force of 6kgf is substantially lower than the D4GL-1EFG-A at 102kgf; mechanical locking requirements must be assessed accordingly.

Mechanical Interface Considerations: Conduit thread size differs (M20 for D4SL-N versus PG14.6 for D4GL-1EFG-A). Panel mounting and conduit connection hardware must be adapted to the substitute part specifications.

Regulatory Compliance: Both D4SL-N substitute options maintain CE and TUV approvals. The D4SL-N series adds CCC certification. All three parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4EFG-D or D4SL-N4EFG-DN be used as direct drop-in replacements for D4GL-1EFG-A?

A: Functional substitution is possible for applications where the load voltage and current requirements do not exceed D4SL-N series ratings (120VAC, 1.5A AC, 220mA DC). Mechanical interface adaptation is required due to different conduit thread sizes (M20 versus PG14.6). Holding force reduction from 102kgf to 6kgf must be evaluated for the specific locking application.

Q: What is the difference between D4SL-N4EFG-D and D4SL-N4EFG-DN?

A: Both parts are functionally identical with the same electrical specifications and performance characteristics. The sole difference is termination style: D4SL-N4EFG-D uses screw terminals, while D4SL-N4EFG-DN uses connector termination. Selection depends on the wiring and connection method required by the system design.

Q: Why does the D4SL-N series have lower holding force than the D4GL-1EFG-A?

A: The D4SL-N series represents a different design generation within the Omron interlock solenoid locking switch family, optimized for different mechanical load requirements. Applications requiring 102kgf holding force must retain the D4GL-1EFG-A or identify alternative parts with equivalent force specifications.

Q: Are there any regulatory compliance differences between the original and substitute parts?

A: The D4GL-1EFG-A carries CE, cULus, and TUV approvals. The D4SL-N series carries CCC, CE, cURus, and TUV approvals. Both maintain MSL 1 (Unlimited) rating. The D4SL-N series provides expanded regulatory coverage suitable for broader market applications.

Q: What inventory status should be considered when selecting between D4SL-N4EFG-D and D4SL-N4EFG-DN?

A: D4SL-N4EFG-D has 780 pcs in stock; D4SL-N4EFG-DN has 846 pcs in stock. Both are actively produced and available. Selection should be based on termination style requirements rather than inventory considerations.

Q: Can the D4SL-N series handle 240VAC load switching like the original D4GL-1EFG-A?

A: No. The D4SL-N series is rated for 120VAC load voltage maximum, compared to 240VAC for the D4GL-1EFG-A. Applications requiring 240VAC switching capability cannot use the D4SL-N series as a substitute.
