E3S-5LE41 Equivalent & Substitute Parts

Part Overview

The E3S-5LE41 is a through-beam optical sensor manufactured by Omron Automation and Safety, designed for industrial automation applications requiring long-distance object detection. This sensor operates with a 5-meter sensing distance and features selectable dark-ON/light-ON output logic with NPN configuration. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and new installations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E3S-5LE41 are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Sensing method: Through-beam configuration
• Voltage supply range: 12V ~ 24V operation
• Output logic: NPN configuration with selectable dark-ON/light-ON capability
• Light source: Infrared spectrum
• Connection method: Cable-based interface
• Operating temperature range: -25°C ~ 55°C
• Ingress protection: IP67 minimum rating

The E3S-5LE41 has two identified substitute parts: E3S-CT61 and E3Z-T61. Both maintain the core through-beam sensing architecture and voltage/temperature specifications. Differences exist in sensing distance, response time, and output configuration flexibility, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

E3S-CT61 Selection Criteria: The E3S-CT61 is an active product offering extended sensing distance (30m) compared to the E3S-5LE41 (5m). This substitute provides improved response time (1ms vs. 3ms) and dual output configuration support (NPN/PNP). The E3S-CT61 includes adjustable potentiometer control and carries REACH compliance status. Select this substitute when applications require longer detection ranges or when PNP output capability is beneficial for system integration.

E3Z-T61 Selection Criteria: The E3Z-T61 is an active product with intermediate sensing distance (15m) and faster response time (1ms). This substitute maintains NPN-only output configuration matching the E3S-5LE41 architecture. The E3Z-T61 provides enhanced ingress protection (IP69K) and carries RoHS compliance. Select this substitute for applications requiring moderate sensing distance with improved environmental protection ratings.

Both substitute parts maintain the 12V ~ 24V supply voltage and -25°C ~ 55°C operating temperature range of the original E3S-5LE41, ensuring compatibility with existing power infrastructure and thermal environments.

Frequently Asked Questions (FAQ)

Q: Can the E3S-CT61 directly replace the E3S-5LE41 in existing installations?

A: The E3S-CT61 maintains compatibility with the core electrical parameters (12V ~ 24V supply, -25°C ~ 55°C operation, cable connection). However, the extended sensing distance (30m vs. 5m) and faster response time (1ms vs. 3ms) may affect system behavior. Verify that your application can accommodate the increased detection range and faster response characteristics before substitution.

Q: What is the difference between E3S-CT61 and E3Z-T61 for my application?

A: The primary differences are sensing distance and output configuration. The E3S-CT61 offers 30m range with NPN/PNP flexibility, while the E3Z-T61 provides 15m range with NPN-only output. The E3Z-T61 includes enhanced ingress protection (IP69K). Select based on your required sensing distance and whether PNP output capability is needed.

Q: Are the substitute parts compatible with the same mounting and connector interfaces?

A: All three sensors use cable-based connections. Verify physical mounting dimensions and connector specifications with your system design before implementation, as mechanical compatibility is not detailed in the provided parameters.

Q: What compliance certifications should I consider when selecting a substitute?

A: The E3S-CT61 carries REACH compliance status, while the E3Z-T61 is REACH unaffected. Both active substitutes maintain the same ECCN (EAR99) and HTSUS classification as the original E3S-5LE41. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Why is the E3S-5LE41 listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The identified substitute parts (E3S-CT61 and E3Z-T61) are active products that provide equivalent through-beam sensing functionality with enhanced specifications.
