Key Parameters

Substitute Part Grouping Explanation

Substitution of the E3FZ-D87 is based on the following critical parameters that define functional equivalence:

• Sensing Method: Reflective optical sensing capability
• Output Configuration: PNP output with Dark-ON/Light-ON selectable modes
• Supply Voltage Range: 10V ~ 30V compatibility
• Connection Method: Connector-based interface
• Ingress Protection: IEC IP67, IP69K ratings
• Operating Temperature Range: -25°C ~ 55°C

The E3FA-DP23 qualifies as a substitute based on matching these core parameters. While the sensing distance differs (700mm versus 1mm), both sensors operate within the same electrical and environmental specifications, allowing for application-dependent selection based on required detection range.

Parameter Comparison

Engineering Selection Recommendations

The E3FA-DP23 is available as an active product with current manufacturing status, whereas the E3FZ-D87 is obsolete. Selection between these components depends on application-specific sensing distance requirements:

• For 1mm sensing distance applications: The E3FZ-D87 specifications define the required detection range. Substitution with E3FA-DP23 is not recommended for applications requiring short-range detection due to its 700mm sensing distance.

• For applications tolerant of extended sensing distance: The E3FA-DP23 provides an active, supported alternative with identical electrical characteristics, improved response time (500µs versus 1ms), and equivalent environmental protection ratings.

Both components maintain ROHS3 compliance status and carry identical supply voltage, output configuration, and ingress protection specifications. The E3FA-DP23 features a Red LED light source compared to the infrared (860nm) source of the E3FZ-D87, which may affect performance in applications with specific optical filtering or ambient light conditions.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-DP23 directly replace the E3FZ-D87 in existing designs?

A: Direct replacement depends on sensing distance requirements. Both sensors share identical supply voltage (10V ~ 30V), PNP output configuration with selectable Dark-ON/Light-ON modes, connector-based interface, and environmental protection ratings (IEC IP67, IP69K). The primary difference is sensing distance: E3FZ-D87 operates at 1mm while E3FA-DP23 operates at 700mm. Substitution is valid only if the application can accommodate the extended detection range.

Q: What are the key electrical compatibility factors?

A: Both the E3FZ-D87 and E3FA-DP23 operate within 10V ~ 30V supply voltage range and feature PNP output with selectable Dark-ON/Light-ON output modes. Connector-based connection methods are identical, ensuring mechanical and electrical interface compatibility at the circuit level.

Q: How do the light sources differ between these sensors?

A: The E3FZ-D87 uses infrared light at 860nm wavelength, while the E3FA-DP23 uses a Red LED light source. This difference may affect performance in applications with specific optical filtering, reflective surface characteristics, or ambient light environments. Applications sensitive to light wavelength should evaluate both options under actual operating conditions.

Q: What is the significance of the product status difference?

A: The E3FZ-D87 is classified as obsolete, indicating discontinued manufacturing and limited availability. The E3FA-DP23 maintains active product status with current manufacturing support, ensuring long-term availability and technical support from Omron Automation and Safety.

Q: Are there environmental operating differences?

A: Both sensors operate across the identical temperature range of -25°C to 55°C and maintain equivalent ingress protection ratings (IEC IP67, IP69K). Environmental performance specifications are fully compatible between the two components.

Q: How do response times compare?

A: The E3FZ-D87 has a response time of 1ms, while the E3FA-DP23 provides faster response at 500µs. For applications requiring rapid detection cycles, the E3FA-DP23 offers improved performance. For standard industrial applications, both response times are typically acceptable.
