E3F2-LS10B4 Equivalent & Substitute Parts

Part Overview

The Omron E3F2-LS10B4 is a reflective, background suppression optical sensor with a 100mm (3.937") sensing distance and selectable dark-ON/light-ON output configuration. This PNP sensor operates across a 10V to 30V supply range with a 1ms response time and is housed in an axial wire connection format. The product is classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the E3F2-LS10B4 is determined by alignment across the following critical parameters:

• Sensing Distance: 100mm (3.937") — must match exactly
• Output Configuration: PNP with selectable dark-ON/light-ON operation
• Supply Voltage Range: 10V ~ 30V compatibility
• Sensing Method: Reflective optical detection
• Ingress Protection: IEC IP67, IP69K rating
• Operating Temperature Range: -25°C ~ 55°C
• Light Source: Red wavelength (660nm or Red LED)

The E3FA-DP11 2M meets all critical substitution criteria. While it transitions from axial wire connection to a 2-meter cable format and improves response time from 1ms to 500µs, these represent functional enhancements rather than compatibility barriers. The substitute maintains identical sensing distance, voltage supply range, output configuration, ingress protection, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The E3FA-DP11 2M is the direct functional equivalent for E3F2-LS10B4 replacement. The substitute is an active product with current manufacturing support, whereas the original is obsolete. The E3FA-DP11 2M carries ROHS3 compliance certification, meeting modern environmental and regulatory standards.

The transition from discrete wire connection to a pre-assembled 2-meter cable requires mechanical integration review in the target application. The improved response time (500µs versus 1ms) represents a performance enhancement with no negative compatibility implications. Both sensors maintain identical sensing distance, voltage supply specifications, output logic selectability, and environmental protection ratings.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-DP11 2M directly replace the E3F2-LS10B4 in existing installations?

A: Yes, provided the 2-meter cable length accommodates the physical installation. Both sensors share identical sensing distance (100mm), supply voltage range (10V–30V), output configuration (PNP selectable), and environmental ratings (IP67/IP69K). The cable-based connection of the substitute requires mechanical routing consideration absent in the original wire format.

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

A: Both are reflective optical sensors. Background suppression is a specific reflective sensing variant that filters ambient light interference. The E3FA-DP11 2M uses standard reflective sensing. Compatibility is maintained because both operate at the same 100mm sensing distance with identical output logic.

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

A: No. The 500µs response time of the E3FA-DP11 2M is faster than the original 1ms specification, representing an improvement. Applications designed for 1ms response will function correctly with the faster substitute.

Q: Is the 2-meter cable length fixed on the E3FA-DP11 2M?

A: Yes. The E3FA-DP11 2M includes a permanently attached 2-meter cable. If a different cable length is required, alternative E3FA series configurations with different cable lengths may be available through the manufacturer.

Q: What compliance certifications apply to the substitute?

A: The E3FA-DP11 2M is ROHS3 compliant and REACH unaffected. Both sensors carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.
