Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E3X-DA11AT-S 2M are identified based on the following critical parameters that determine functional compatibility:

• Voltage Supply Range: The original part operates at 12V ~ 24V. Substitute parts must support this voltage range or provide overlapping coverage.
• Output Type: NPN output configuration is required for direct replacement in existing circuits.
• Amplifier Classification: The original part functions as an ATC Output amplifier. Substitute parts classified as Standard Sensor Amplifiers can provide equivalent functionality when other parameters align.
• Mounting Configuration: DIN Rail mounting is the specified form factor.
• Supply Current: The original part draws 40 mA maximum. Substitute parts with equal or lower current draw are compatible.
• Regulatory Compliance: ECCN and HTSUS classifications must remain consistent for supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

E3X-HD11 2M is the primary substitute for the E3X-DA11AT-S 2M. Both parts share identical voltage supply range (12V ~ 24V), NPN output configuration, and HTSUS classification (8543.70.9860). The E3X-HD11 2M is an active product with current manufacturing support, eliminating obsolescence concerns. Supply current is 60 mA compared to the original 40 mA, which remains within acceptable operational parameters for most DIN Rail installations. Operating temperature range is specified for the substitute (-25°C ~ 55°C), providing defined thermal performance.

E3NX-FA21 2M serves as a secondary substitute option. This part operates within a broader voltage supply range (10V ~ 30V), which encompasses the original 12V ~ 24V specification. The E3NX-FA21 2M is an active product with established supply availability. Output type specifications are not provided for this part, requiring verification against specific circuit requirements before deployment.

Both substitute parts are manufactured by Omron Automation and Safety, maintaining supply chain consistency and technical support continuity.

Frequently Asked Questions (FAQ)

Q: Can the E3NX-FA21 2M directly replace the E3X-DA11AT-S 2M in existing installations?

A: The E3NX-FA21 2M provides voltage supply compatibility (10V ~ 30V range covers the original 12V ~ 24V requirement) and is manufactured by the same supplier. However, output type specifications are not provided for the E3NX-FA21 2M. Verification of output configuration compatibility with existing circuit connections is required before substitution.

Q: What is the impact of the higher supply current in the E3X-HD11 2M (60 mA vs. 40 mA)?

A: The E3X-HD11 2M draws 20 mA additional current compared to the original part. This increased current draw must be evaluated against the power supply capacity in the target installation. Most industrial DIN Rail power supplies accommodate this current increase without modification.

Q: Are there packaging differences between the original and substitute parts?

A: The E3X-DA11AT-S 2M packaging is not specified in available documentation. The E3NX-FA21 2M is supplied in Bulk packaging, while the E3X-HD11 2M is supplied in Box packaging. Physical dimensions and connector configurations should be verified for mechanical fit in the target installation.

Q: Why is the E3X-DA11AT-S 2M classified as obsolete?

A: Obsolescence classification indicates the part is no longer in active production. The E3X-HD11 2M and E3NX-FA21 2M are both active products with current manufacturing support, providing long-term supply security for new installations and system upgrades.

Q: Do the substitute parts maintain the same regulatory compliance as the original?

A: All three parts share identical ECCN classification (EAR99) and MSL rating (1 - Unlimited). The E3X-HD11 2M additionally carries RoHS3 Compliance and REACH Affected designations, providing enhanced environmental compliance documentation.
