Key Parameters

Substitute Part Grouping Explanation

The E3FA-LN11 2M qualifies as a functional substitute for the E3F2-LS10C4 based on the following critical parameters:

Matching Parameters:

• Sensing distance: 3.937" (100mm)
• Voltage supply range: 10V ~ 30V
• Output configuration: NPN - Dark-ON/Light-ON - Selectable
• Light source: Red LED
• Ingress protection: IEC IP67, IP69K
• Operating temperature range: -25°C ~ 55°C
• Manufacturer: Omron Automation and Safety

Substitution Logic: The E3FA-LN11 2M maintains electrical and mechanical compatibility through identical sensing distance, voltage specifications, and output characteristics. Both sensors employ reflective optical detection with selectable output modes suitable for equivalent application requirements. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The E3FA-LN11 2M is the designated substitute for the obsolete E3F2-LS10C4. Selection of this alternative is supported by:

• Product Status: The substitute maintains active production status, ensuring availability and ongoing manufacturer support, whereas the main part is obsolete.
• Electrical Compatibility: Both sensors operate within identical voltage supply ranges (10V ~ 30V) and provide equivalent NPN output configurations with selectable Dark-ON/Light-ON modes.
• Sensing Performance: Both parts maintain the same 100mm sensing distance and operate across the same temperature range (-25°C ~ 55°C).
• Regulatory Compliance: Both sensors carry identical ingress protection ratings (IEC IP67, IP69K) and ECCN classification (EAR99), ensuring compliance with existing system certifications.
• Response Time Improvement: The substitute offers a faster response time (500µs versus 1ms), providing enhanced performance in time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-LN11 2M directly replace the E3F2-LS10C4 in existing installations?

A: Yes. Both sensors share identical sensing distance (100mm), voltage supply range (10V ~ 30V), output configuration (NPN with selectable Dark-ON/Light-ON), and environmental ratings (IP67, IP69K). The primary difference is connection method: the E3F2-LS10C4 uses wire connection while the E3FA-LN11 2M uses a 2-meter cable. System integration may require connector adaptation.

Q: What is the difference between "Reflective, Background Suppression" and "Reflective" sensing methods?

A: Both employ reflective optical detection. Background suppression specifically filters ambient light interference, while standard reflective sensing detects reflected light from target objects. The E3FA-LN11 2M's reflective method remains compatible with applications designed for the E3F2-LS10C4.

Q: Does the faster response time (500µs vs. 1ms) affect compatibility?

A: No. The substitute's faster response time represents an improvement and does not create incompatibility. Applications designed for 1ms response will function correctly with 500µs response.

Q: Are there packaging or inventory considerations?

A: The E3F2-LS10C4 is obsolete with 783 units in stock. The E3FA-LN11 2M is active production with 914 units available. For new designs or long-term supply requirements, the active substitute is recommended.

Q: What adjustment differences exist between these sensors?

A: The E3F2-LS10C4 features fixed adjustment, while the E3FA-LN11 2M includes single-turn adjustment capability. This provides greater flexibility in the substitute for field calibration and sensitivity tuning.
