E3FZ-LS89H Equivalent & Substitute Parts

Part Overview

The E3FZ-LS89H is a reflective, diffuse optical sensor manufactured by Omron Automation and Safety, designed for 200mm (7.874") sensing distance applications with PNP output configuration. This sensor features selectable Dark-ON/Light-ON operation and operates across a 10V to 30V supply voltage range. The product is currently classified as obsolete, making identification of compatible substitute components essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the E3FZ-LS89H is determined by the following critical parameters:

• Sensing Distance: 7.874" (200mm) — must match exactly
• Output Configuration: PNP with Dark-ON/Light-ON selectable operation
• Supply Voltage Range: 10V ~ 30V
• Sensing Method: Reflective operation capability
• Light Source: Red wavelength (660nm or Red LED)
• Connection Method: Connector-based interface
• Ingress Protection: IEC IP67, IP69K rating
• Operating Temperature Range: -25°C ~ 55°C

The E3FA-LP22 satisfies all these substitution criteria, providing functional and electrical equivalence despite differences in response time and product status classification.

Engineering Selection Recommendations

The E3FA-LP22 is the qualified substitute for the obsolete E3FZ-LS89H based on the following engineering criteria:

Product Status & Availability: The E3FZ-LS89H is classified as obsolete, while the E3FA-LP22 maintains active product status with confirmed inventory availability (908 Pcs New Original In Stock). This ensures long-term supply chain viability and continued manufacturer support.

Regulatory Compliance: The E3FA-LP22 carries ROHS3 compliance certification and REACH Affected status, meeting current environmental and regulatory requirements. The E3FZ-LS89H shows vendor-undefined REACH status, indicating potential compliance gaps for new designs or system updates.

Functional Equivalence: Both sensors operate identically across all critical electrical and mechanical parameters: 200mm sensing distance, PNP output with selectable Dark-ON/Light-ON operation, 10V–30V supply voltage, connector-based interface, and IEC IP67/IP69K ingress protection. Operating temperature ranges are identical (-25°C to 55°C).

Performance Differential: The E3FA-LP22 provides superior response time (500µs versus 1ms), representing a 2× improvement in switching speed. This enhancement does not compromise backward compatibility and may improve system responsiveness in time-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-LP22 directly replace the E3FZ-LS89H in existing installations?

A: Yes. Both sensors share identical sensing distance (200mm), output configuration (PNP with selectable Dark-ON/Light-ON), supply voltage range (10V–30V), connection method (connector), and environmental ratings (IP67/IP69K). Mechanical and electrical interfaces are compatible.

Q: What is the significance of the response time difference (1ms vs. 500µs)?

A: The E3FA-LP22 responds twice as fast as the E3FZ-LS89H. For most industrial applications, this improvement is transparent and does not require
