E3S-2LE4 Equivalent & Substitute Parts

Part Overview

The E3S-2LE4 is a through-beam optical sensor manufactured by Omron Automation and Safety with a sensing distance of 78.740" (2m). This NPN sensor features selectable Dark-ON/Light-ON output configuration and operates across 12V to 24V supply voltage. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E3S-2LE4 are identified based on the following core compatibility parameters:

• Through-beam sensing method (required for functional equivalence)
• NPN output configuration with Dark-ON/Light-ON selectability (required for signal compatibility)
• 12V ~ 24V supply voltage compatibility (required for electrical integration)
• Cable connection method (required for installation compatibility)
• Operating temperature range of -25°C ~ 55°C or broader (required for environmental compatibility)

The E3S-AT11 and E3Z-T61 both satisfy these core requirements. Differences in sensing distance, response time, light source wavelength, and ingress protection rating represent variations in performance capability rather than incompatibility. Selection between substitutes depends on application-specific requirements for detection range and environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

Both E3S-AT11 and E3Z-T61 are active products suitable for replacing the obsolete E3S-2LE4 in applications requiring through-beam optical sensing with NPN output and 12V to 24V operation.

The E3S-AT11 provides extended sensing distance (7m versus 2m) with improved response time (500µs versus 3ms) and enhanced ingress protection (IP67 versus IP65). This substitute is appropriate for applications requiring longer detection range or operation in more demanding environmental conditions. The E3S-AT11 is RoHS3 compliant and REACH affected.

The E3Z-T61 offers maximum sensing distance (15m) with the fastest response time (1ms) and highest ingress protection rating (IP67, IP69K). This substitute is suitable for applications requiring extended range detection or operation in harsh environments including high-pressure washdown conditions. The E3Z-T61 is RoHS compliant and REACH unaffected.

Selection between substitutes should prioritize application-specific requirements for detection range, environmental protection, and compliance certifications. Both alternatives maintain electrical and mechanical compatibility with the original E3S-2LE4 specification.

Frequently Asked Questions (FAQ)

Q: Can the E3S-AT11 or E3Z-T61 directly replace the E3S-2LE4 in existing installations?

A: Yes. Both substitutes maintain identical supply voltage (12V ~ 24V), output configuration (NPN with Dark-ON/Light-ON selectability), connection method (cable), and operating temperature range (-25°C ~ 55°C). Mechanical mounting and electrical integration are compatible. The primary difference is increased sensing distance, which does not prevent installation in applications originally designed for 2m range.

Q: What is the difference between the E3S-AT11 and E3Z-T61?

A: The E3Z-T61 provides greater sensing distance (15m versus 7m), faster response time (1ms versus 500µs), and higher ingress protection (IP67, IP69K versus IP67). The E3S-AT11 uses red light (700nm) while the E3Z-T61 uses infrared (870nm). Selection depends on application requirements for detection range and environmental conditions.

Q: Are there packaging differences between these parts?

A: The E3S-2LE4 original packaging is not specified in available data. Both E3S-AT11 and E3Z-T61 are supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: What compliance certifications apply to these substitutes?

A: The E3S-AT11 is RoHS3 compliant and REACH affected. The E3Z-T61 is RoHS compliant and REACH unaffected. Both parts carry ECCN EAR99 classification and HTSUS code 8541.49.8000. Verify compliance requirements against your application and regulatory jurisdiction.

Q: How do the ingress protection ratings affect application suitability?

A: The E3S-2LE4 provides IP65 protection (dust-tight, low-pressure water jets). The E3S-AT11 provides IP67 protection (temporary immersion). The E3Z-T61 provides IP67 and IP69K protection (high-pressure, high-temperature washdown). Select based on environmental exposure: IP65 for dry/light spray environments, IP67 for wet environments, IP69K for high-pressure washdown applications.
