E3S-2LE41 Equivalent & Substitute Parts

Part Overview

The E3S-2LE41 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 equivalent substitute parts necessary for system maintenance, repair, and new design implementations where through-beam sensing at comparable or extended ranges is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E3S-2LE41 is determined by the following core parameters:

• Sensing method must remain through-beam
• Output configuration must support NPN with Dark-ON/Light-ON selectable operation
• Voltage supply range must encompass or be compatible with 12V ~ 24V
• Connection method must be cable-based
• Operating temperature range must maintain -25°C ~ 55°C minimum coverage
• Light source type (infrared or red) is acceptable for through-beam applications

The E3S-AT61 and E3Z-T61 satisfy these substitution criteria while offering extended sensing distances and improved product status (both active). These parts maintain functional compatibility with the original E3S-2LE41 circuit topology and control logic.

Parameter Comparison

Engineering Selection Recommendations

Both E3S-AT61 and E3Z-T61 are active products suitable for replacing the obsolete E3S-2LE41. Selection between these substitutes depends on application-specific sensing distance requirements:

The E3S-AT61 provides a 7-meter sensing distance with improved ingress protection (IP67) and faster response time (500µs). This part is ROHS3 compliant and REACH affected, meeting current environmental regulations.

The E3Z-T61 extends sensing capability to 15 meters with the highest ingress protection rating (IP67, IP69K) and RoHS compliance. This part is REACH unaffected and offers the fastest response time (1ms) among the three options.

Both substitutes maintain identical voltage supply ranges, output configuration flexibility, and operating temperature specifications as the original E3S-2LE41, ensuring direct functional replacement in existing control circuits.

Frequently Asked Questions (FAQ)

Q: Can E3S-AT61 or E3Z-T61 directly replace E3S-2LE41 in existing installations?

A: Yes. Both substitute parts maintain identical voltage supply (12V ~ 24V), NPN output configuration with selectable Dark-ON/Light-ON operation, cable connection method, and operating temperature range (-25°C ~ 55°C). Circuit-level compatibility is preserved.

Q: What is the primary difference between E3S-AT61 and E3Z-T61?

A: Sensing distance and ingress protection differ. E3S-AT61 provides 7-meter range with IP67 protection. E3Z-T61 extends to 15-meter range with IP67 and IP69K protection. Response times also differ: E3S-AT61 at 500µs versus E3Z-T61 at 1ms.

Q: Does light source type affect substitution compatibility?

A: No. The E3S-2LE41 uses infrared, while E3S-AT61 uses red (700nm) and E3Z-T61 uses infrared (870nm). All three light sources are compatible with through-beam sensing applications and do not affect output signal characteristics or control logic.

Q: Are there packaging differences between these parts?

A: E3S-2LE41 packaging is unspecified. Both E3S-AT61 and E3Z-T61 are supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Which substitute offers better environmental compliance?

A: E3S-AT61 is ROHS3 compliant and REACH affected. E3Z-T61 is RoHS compliant and REACH unaffected. Selection depends on your specific regulatory requirements and supply chain constraints.
