Omron D4GL-1AFA-A Interlock Solenoid Release DPST - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-1AFA-A is an interlock solenoid release switch designed for panel disconnect applications with dual-pole, single-throw configuration. This component operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf. The part is classified as obsolete, making equivalent substitute parts necessary for new designs and system replacements where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

The D4GL-1AFA-A has been superseded by parts from the D4SL-N series. Substitution is based on the following criteria:

Maintained Compatibility Parameters:

• Circuit configuration: DPST-NO/NC (DB/DM) x 2
• Actuator type: Panel Disconnect
• Ingress protection: IP67
• Operating temperature range: -10°C to 55°C
• Moisture sensitivity level: 1 (Unlimited)
• Manufacturer: Omron Automation and Safety

Modified Parameters:

• Voltage rating: Changed from 240VAC to 120VAC/125VDC
• Current rating: Changed from 750mA AC to 1.5A AC / 220mA DC
• Holding force: Reduced from 102kgf to 6kgf
• Conduit thread size: Changed from PG14.6 to M20
• Product status: Changed from Obsolete to Active
• Termination style: Available in both Screw Terminal and Connector options

The D4SL-N series represents the active product line replacement with enhanced electrical ratings and modern connector options while maintaining core functional and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Screw Terminal): Select D4SL-N4AFA when the original D4GL-1AFA-A requires replacement in existing installations with screw terminal connections. This part maintains the same termination interface and is actively manufactured with current compliance certifications (CCC, CE, cURus, TUV).

For New Designs or Connector-Based Systems: Select D4SL-N4AFA-N when designing new systems or when connector-based termination is preferred. This variant offers the same electrical and environmental specifications as D4SL-N4AFA with connector termination instead of screw terminals.

Voltage and Current Considerations: Both D4SL-N variants operate at 120VAC/125VDC, which differs from the original 240VAC specification. System voltage requirements must be evaluated during selection. The D4SL-N series provides higher AC current capacity (1.5A versus 750mA) and includes DC current rating capability (220mA).

Holding Force Difference: The D4SL-N series provides 6kgf holding force compared to the original 102kgf. Applications requiring the original holding force specification may require alternative evaluation beyond this substitute series.

Compliance and Availability: Both D4SL-N variants carry active product status with expanded approval certifications. D4SL-N4AFA inventory: 949 units; D4SL-N4AFA-N inventory: 1090 units.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4AFA directly replace D4GL-1AFA-A in all applications? A: Direct replacement is possible for the circuit configuration, actuator type, and environmental specifications. However, voltage rating (120VAC/125VDC versus 240VAC) and holding force (6kgf versus 102kgf) must be verified against system requirements.

Q: What is the difference between D4SL-N4AFA and D4SL-N4AFA-N? A: Both parts are electrically and functionally identical. The primary difference is termination style: D4SL-N4AFA uses screw terminals, while D4SL-N4AFA-N uses connector termination. Selection depends on the connection method required by the application.

Q: Why is the holding force lower in the D4SL-N series? A: The D4SL-N series represents a different product line within the Omron interlock solenoid release family. The 6kgf holding force is the specified value for this series. Applications requiring 102kgf holding force require evaluation of alternative product lines.

Q: Are the D4SL-N variants suitable for the same voltage systems as the original D4GL-1AFA-A? A: No. The D4GL-1AFA-A operates at 240VAC with 24VDC supply, while D4SL-N variants operate at 120VAC/125VDC. System voltage compatibility must be confirmed before substitution.

Q: What certifications do the substitute parts carry? A: D4SL-N4AFA and D4SL-N4AFA-N carry CCC, CE, cURus, and TUV certifications. The original D4GL-1AFA-A carried CE, cULus, and TUV certifications. The expanded certification set reflects current regulatory requirements.

Q: Is the D4GL-1AFA-A still available? A: The D4GL-1AFA-A is classified as obsolete. Current inventory exists (1037 units), but no new production is planned. The D4SL-N series represents the active replacement line.
