Omron D4GL-4CFG-A4-NPT Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4CFG-A4-NPT is a solenoid locking interlock switch designed for panel disconnect applications with dual-pole switching capability. This component features a 24VDC supply voltage, 240VAC switching rating, and 102kgf holding force, housed in an IP67-rated enclosure with M20 conduit threading. The product is currently obsolete, necessitating identification of active equivalent models that maintain functional and electrical compatibility for continued system operation and new installations.

Key Parameters

Substitute Part Grouping Explanation

The D4GL-4CFG-A4-NPT has been superseded by the D4SL-N series from Omron Automation and Safety. Substitution is based on the following critical parameters that remain consistent across both the obsolete and active models:

• Solenoid Locking Type: Both main and substitute parts function as solenoid locking interlock switches
• Circuit Configuration: Identical DPST-NO/NC + DPST-NC switching arrangement
• Actuator Type: Panel Disconnect functionality maintained
• Termination Style: Screw Terminal connections preserved
• Ingress Protection: IP67 rating maintained for dust and water resistance
• Operating Temperature Range: -10°C ~ 55°C range consistent
• Moisture Sensitivity Level: MSL 1 (Unlimited) maintained

The D4SL-N3CFG and D4SL-N3CFG-N variants represent the active product line replacements, both carrying Active product status with enhanced electrical specifications and expanded approval certifications.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N3CFG and D4SL-N3CFG-N are qualified replacements for the obsolete D4GL-4CFG-A4-NPT. Selection between the two active variants should be based on application-specific requirements:

D4SL-N3CFG is suitable for applications requiring standard bulk packaging with active product support and full compliance certifications including CCC, CE, cURus, and TUV standards.

D4SL-N3CFG-N provides identical electrical and mechanical specifications with equivalent compliance certifications, also available in bulk packaging.

Both substitute parts offer enhanced electrical performance compared to the original component, with increased AC current rating (1.5A versus 750mA) and higher holding force (133kgf versus 102kgf). The shift from M20 to 1/2" NPT conduit threading requires mechanical interface verification during installation. Supply voltage options expand to include 120VAC and 125VDC alongside the original 24VDC specification, providing greater application flexibility.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N3CFG or D4SL-N3CFG-N directly replace D4GL-4CFG-A4-NPT in existing installations?

A: Both D4SL-N series parts maintain identical circuit configuration (DPST-NO/NC + DPST-NC), actuator type (Panel Disconnect), termination style (Screw Terminal), and ingress protection rating (IP67). However, the conduit thread size differs: the original uses M20 while the substitutes use 1/2" NPT. Mechanical interface compatibility must be verified before installation.

Q: What are the key electrical differences between the obsolete and substitute parts?

A: The D4SL-N3CFG and D4SL-N3CFG-N provide enhanced electrical specifications: AC current rating increases from 750mA to 1.5A, and holding force increases from 102kgf to 133kgf. Supply voltage options expand from 24VDC only to include 120VAC and 125VDC. Switching voltage rating changes from 240VAC to 120VAC.

Q: Are there packaging differences between D4SL-N3CFG and D4SL-N3CFG-N?

A: Both substitute parts are supplied in bulk packaging. No functional or electrical differences exist between these two variants; selection may be based on inventory availability or specific procurement requirements.

Q: What compliance certifications apply to the substitute parts?

A: Both D4SL-N3CFG and D4SL-N3CFG-N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the original D4GL-4CFG-A4-NPT (CE, cULus, TUV).

Q: Is the operating temperature range maintained in the substitute parts?

A: Yes, all three parts operate within the identical temperature range of -10°C to 55°C.
