Key Parameters

Substitute Part Grouping Explanation

Substitution of the E3F2-D1C4 2M is determined by the following critical parameters:

• Sensing method classification (Reflective)
• Output type (NPN with selectable Dark-ON/Light-ON capability)
• Supply voltage range compatibility (10V ~ 30V)
• Ingress protection rating (IEC IP67, IP69K minimum)
• Operating temperature range (-25°C ~ 55°C)
• Manufacturer series compatibility (Omron E3 series optical sensors)

The E3FA-DN13 2M qualifies as a substitute based on matching these core electrical and environmental specifications. Variations in sensing distance, response time, light source wavelength, and connection method represent acceptable trade-offs within the optical sensor category when the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

The E3FA-DN13 2M is an active product from Omron's current optical sensor portfolio, providing continuity for applications previously using the obsolete E3F2-D1C4 2M. Both sensors maintain identical supply voltage ranges and output configurations, ensuring direct compatibility in control circuit integration.

The substitute part delivers faster response time (500µs versus 1ms), which represents improved performance characteristics. The reduced sensing distance (700mm versus 1000mm) requires verification against specific application requirements. Both sensors maintain equivalent environmental protection ratings (IEC IP67, IP69K) and operating temperature specifications.

The E3FA-DN13 2M includes RoHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. The cable connection method and Red LED light source differ from the original part but do not preclude functional substitution when mechanical integration accommodates these changes.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-DN13 2M directly replace the E3F2-D1C4 2M in existing installations?

A: Electrical compatibility is confirmed through matching supply voltage (10V ~ 30V), NPN output configuration with selectable Dark-ON/Light-ON modes, and identical environmental protection ratings. Mechanical integration requires assessment of connection method differences (cable versus wire) and sensing distance reduction (700mm versus 1000mm).

Q: What is the significance of the sensing distance difference between these parts?

A: The E3F2-D1C4 2M operates at 1 meter maximum sensing distance, while the E3FA-DN13 2M operates at 700mm. Applications requiring detection beyond 700mm cannot use the substitute without system redesign. Applications operating within 700mm detection range are unaffected.

Q: How do the light source differences affect substitution?

A: The main part uses Infrared (880nm) while the substitute uses Red LED. Both are reflective sensing technologies suitable for industrial object detection. Red LED sources provide visible indication of sensor operation and may offer different reflectivity characteristics with specific target materials. Application-specific testing is necessary only if target material reflectivity is critical to system performance.

Q: What is the impact of the response time improvement?

A: The E3FA-DN13 2M provides 500µs response time compared to 1ms for the original part. This represents a 2x improvement in detection speed, which benefits high-speed conveyor systems and rapid object detection applications. Systems designed for 1ms response time will function correctly with the faster substitute.

Q: Are there packaging or inventory considerations for this substitution?

A: The E3FA-DN13 2M is supplied in box packaging and is currently in active production with 864 units in stock. The E3F2-D1C4 2M is obsolete. For new designs or system replacements, the active substitute part ensures long-term availability and supply chain continuity.
