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

Part Overview

The Omron D4GL-1DFG-A is an interlock solenoid locking switch classified as a DPST-NC (Double Pole Single Throw - Normally Closed) device designed for panel disconnect applications. This component operates at 24VDC supply voltage with a 240VAC current rating of 750mA and provides a holding force of 102kgf. The D4GL-1DFG-A has reached obsolete product status, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The D4GL-1DFG-A has been superseded by components from the Omron D4SL-N series. Substitution eligibility is determined by the following parameters:

• Circuit configuration: DPST-NC x 2 (maintained across all substitutes)
• Actuator type: Panel Disconnect (maintained across all substitutes)
• Operating temperature range: -10°C to 55°C (maintained across all substitutes)
• Ingress protection: IP67 - Dust Tight, Waterproof (maintained across all substitutes)
• Termination style compatibility: Screw Terminal or Connector options available

The D4SL-N series represents the active product line replacement. Differences in electrical ratings (current and voltage specifications) and holding force reflect design evolution in the product family. Both substitute parts maintain the core solenoid locking functionality and environmental protection standards required for panel disconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Selection between D4SL-N4DFG and D4SL-N4DFG-N should be based on termination requirements:

• D4SL-N4DFG: Select when screw terminal connections are required in the application. This part maintains compatibility with existing screw-based wiring infrastructure.

• D4SL-N4DFG-N: Select when connector-based termination is specified. This configuration supports modular connection approaches.

Both substitute parts carry active product status with expanded approval agency certifications (CCC, CE, cURus, TUV) compared to the obsolete D4GL-1DFG-A. The D4SL-N series is the current Omron product line for this functional category and is recommended for all new designs and system replacements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4DFG or D4SL-N4DFG-N directly replace D4GL-1DFG-A in existing installations?

A: Both D4SL-N parts maintain the same circuit configuration (DPST-NC x 2), actuator type (Panel Disconnect), operating temperature range (-10°C to 55°C), and ingress protection (IP67). However, differences exist in electrical ratings, holding force, and conduit thread size. Mechanical and electrical compatibility must be verified against specific application requirements before substitution.

Q: What is the difference between D4SL-N4DFG and D4SL-N4DFG-N?

A: The primary difference is termination style. D4SL-N4DFG uses screw terminals, while D4SL-N4DFG-N uses connector-based termination. Both parts are electrically and functionally identical otherwise.

Q: Why does the D4SL-N series have lower holding force (6kgf) compared to D4GL-1DFG-A (102kgf)?

A: The holding force specification reflects design differences between product generations. Application compatibility depends on the specific force requirements of the panel disconnect mechanism in use.

Q: Are there packaging differences between these parts?

A: D4GL-1DFG-A was packaged with a dash designation. Both D4SL-N4DFG and D4SL-N4DFG-N are supplied in bulk packaging.

Q: What certifications apply to the substitute parts?

A: D4SL-N4DFG and D4SL-N4DFG-N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the obsolete D4GL-1DFG-A.
