Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-4GFA-A is based on the following critical parameters that must align across alternatives:

Mandatory Matching Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Release
• Circuit Configuration: 3PST-NC + DPST-NO/NC
• Voltage Supply: 24VDC
• Actuator Type: Panel Disconnect
• Conduit Thread Size: M20
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Features: Status Indicator

Allowable Variation Parameters:

• Product Status: Active alternatives acceptable for obsolete parts
• Termination Style: Screw Terminal or Connector acceptable
• Current Rating: May vary within application requirements
• Voltage Rating: May differ if supply voltage remains 24VDC
• Holding Force: May vary based on application load requirements
• Approval Agencies: Active certifications acceptable

The D4SL-N series (D4SL-N4GFA-D and D4SL-N4GFA-DN) meets all mandatory matching criteria while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4GFA-D (Screw Terminal Configuration)

This substitute maintains screw terminal termination identical to the original D4GL-4GFA-A. The D4SL-N4GFA-D is an active product with current manufacturing support and expanded approval certifications (CCC, CE, cURus, TUV). It satisfies all mandatory functional and mechanical parameters. The reduced holding force (6kgf versus 102kgf) and lower voltage rating (120VAC versus 240VAC) require application-level verification to confirm compatibility with existing system load and switching requirements.

D4SL-N4GFA-DN (Connector Configuration)

This substitute provides identical electrical and mechanical functionality to the D4SL-N4GFA-D with connector-based termination instead of screw terminals. Selection of this variant depends on system integration requirements and existing connector infrastructure. Active product status and current certifications apply identically.

Selection Criteria:

Choose D4SL-N4GFA-D for direct screw terminal replacement compatibility. Choose D4SL-N4GFA-DN if connector-based integration is preferred or required by system design. Both alternatives provide active product status, ensuring long-term availability and technical support from Omron Automation and Safety.

Frequently Asked Questions (FAQ)

Q: Why is the D4GL-4GFA-A classified as obsolete?

A: The D4GL-4GFA-A has been discontinued by Omron Automation and Safety. The D4SL-N series represents the current active product line for equivalent interlock solenoid release functionality.

Q: What is the primary difference between D4SL-N4GFA-D and D4SL-N4GFA-DN?

A: The termination style differs. D4SL-N4GFA-D uses screw terminals for direct wire connection. D4SL-N4GFA-DN uses a connector-based interface. Both maintain identical electrical specifications and mechanical form factors.

Q: Can the D4SL-N series directly replace the D4GL-4GFA-A in existing installations?

A: The D4SL-N series matches all mandatory functional and mechanical parameters including circuit configuration, supply voltage, actuator type, conduit thread size, operating temperature range, and ingress protection rating. Holding force and voltage rating differences require application-level assessment to confirm load and switching compatibility.

Q: Are the approval certifications equivalent between the original and substitute parts?

A: The D4SL-N series carries expanded certifications (CCC, CE, cURus, TUV) compared to the D4GL-4GFA-A (CE, cULus, TUV). Both meet international safety and compliance standards applicable to interlock solenoid release switches.

Q: What inventory status applies to these substitute parts?

A: D4SL-N4GFA-D: 695 Pcs New Original In Stock. D4SL-N4GFA-DN: 997 Pcs New Original In Stock. Both alternatives maintain active manufacturing status with current availability.

Q: How do the current ratings compare?

A: The D4GL-4GFA-A is rated at 750mA AC. The D4SL-N series is rated at 1.5A AC and 220mA DC. The D4SL-N series provides higher AC current capacity, suitable for applications requiring the original 750mA specification.
