Key Parameters

Substitute Part Grouping Explanation

Substitution for the E3X-DA21F-S 2M is determined by the following critical parameters:

• Amplifier Type: Standard sensor amplifier classification
• Voltage - Supply: Operating range of 12V to 24V
• Output Type: NPN open collector configuration
• Operating Temperature: -25°C to 55°C ambient temperature range
• Mounting Type: DIN Rail installation capability

The substitute parts listed below maintain compatibility with these core electrical and mechanical specifications. Substitutes are grouped based on their ability to fulfill the same functional role within systems designed for the E3X-DA21F-S 2M.

Parameter Comparison

Engineering Selection Recommendations

E3NX-FA11 2M: This substitute is an active product from Omron's E3NX series. It maintains the standard amplifier classification and identical operating temperature range. The supply voltage range of 10V to 30V encompasses the original 12V to 24V specification, providing broader compatibility. This part is ROHS3 compliant and REACH affected, meeting current regulatory requirements for new designs and replacements.

E3X-HD11 2M: This substitute is an active product from Omron's E3X-HD series. It matches the original part's voltage supply range (12V ~ 24V) and output type (NPN - Open Collector). The supply current specification of 60 mA exceeds the original 40 mA requirement, ensuring adequate power delivery. This part is ROHS3 compliant and REACH affected, suitable for direct replacement in existing installations and new applications.

Both substitutes are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete E3X-DA21F-S 2M.

Frequently Asked Questions (FAQ)

Q: Can the E3NX-FA11 2M directly replace the E3X-DA21F-S 2M?

A: The E3NX-FA11 2M is electrically compatible based on amplifier type, operating temperature, and MSL rating. However, the output type specification is not provided for the E3NX-FA11 2M. Verification of output configuration compatibility with your specific application circuit is required before implementation.

Q: What is the primary advantage of the E3X-HD11 2M as a substitute?

A: The E3X-HD11 2M provides a direct parameter match for voltage supply (12V ~ 24V), output type (NPN - Open Collector), and operating temperature range. The increased supply current rating of 60 mA versus the original 40 mA provides additional design margin. Both parts are from Omron's E3X series, potentially simplifying integration into existing systems.

Q: Are there packaging differences between the main part and substitutes?

A: The E3X-DA21F-S 2M is packaged as a DIN Rail mount unit. The E3NX-FA11 2M is supplied in bulk packaging, while the E3X-HD11 2M is supplied in box packaging. Mounting type compatibility should be confirmed for your specific installation requirements.

Q: Do the substitute parts meet current compliance standards?

A: Both E3NX-FA11 2M and E3X-HD11 2M are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements. The original E3X-DA21F-S 2M, being obsolete, may not meet these standards.

Q: Which substitute should be selected for new designs?

A: For new designs, either substitute is acceptable based on electrical parameters. The E3X-HD11 2M offers the closest parameter alignment with the original part. The E3NX-FA11 2M provides a broader supply voltage range (10V ~ 30V) for applications requiring extended voltage tolerance.
