Key Parameters

Substitute Part Grouping Explanation

Substitution of the E3F2-D1B4-P1 is evaluated based on the following critical parameters that define functional equivalence:

• Sensing method: Reflective optical sensing capability
• Output configuration: PNP with Dark-ON/Light-ON selectable operation
• Supply voltage range: 10V ~ 30V compatibility
• Ingress protection: IEC IP67 and IP69K ratings
• Connection method: Connector-based interface
• Operating temperature range: -25°C ~ 55°C
• Sensing distance: Proximity to 1-meter specification

The E3FA-DP23 meets these core substitution criteria. While the sensing distance is reduced to 700mm (27.559"), the sensor maintains functional equivalence through identical supply voltage range, PNP output configuration with selectable Dark-ON/Light-ON operation, connector-based connection, and matching ingress protection ratings. The E3FA-DP23 is an active product with current manufacturing status, ensuring long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

The E3FA-DP23 is the designated substitute for the obsolete E3F2-D1B4-P1. Selection of this substitute is supported by the following engineering factors:

Product Status: The E3FA-DP23 maintains active product status with current manufacturing support, ensuring availability for immediate procurement and future replacement needs. The E3F2-D1B4-P1 is obsolete and subject to inventory depletion.

Compliance and Certifications: The E3FA-DP23 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both sensors share identical ingress protection ratings (IEC IP67, IP69K) and operating temperature specifications (-25°C ~ 55°C).

Electrical Compatibility: Both sensors operate within the 10V ~ 30V supply voltage range and feature PNP output configuration with selectable Dark-ON/Light-ON operation, ensuring direct integration into existing control circuits without modification.

Performance Characteristics: The E3FA-DP23 provides faster response time (500µs versus 1ms) and maintains connector-based connection methodology. The primary design difference is the reduced sensing distance (700mm versus 1m) and light source technology (Red LED versus Infrared 880nm). These differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-DP23 directly replace the E3F2-D1B4-P1 in all applications?

A: The E3FA-DP23 is functionally equivalent for applications requiring reflective optical sensing with PNP output and selectable Dark-ON/Light-ON operation within the 10V ~ 30V supply range. The reduced sensing distance (700mm versus 1m) and different light source (Red LED versus Infrared 880nm) must be evaluated against specific application requirements. Physical mounting and connector compatibility must be verified.

Q: What is the primary difference between these two sensors?

A: The main differences are sensing distance (E3F2-D1B4-P1: 1m; E3FA-DP23: 700mm), light source technology (Infrared 880nm versus Red LED), and response time (1ms versus 500µs). Both sensors maintain identical supply voltage range, output configuration, ingress protection ratings, and operating temperature specifications.

Q: Why is the E3F2-D1B4-P1 classified as obsolete?

A: The E3F2-D1B4-P1 is listed as obsolete by the manufacturer. The E3FA-DP23 represents the current active product line for equivalent reflective optical sensing applications.

Q: Are there packaging differences between these sensors?

A: The E3F2-D1B4-P1 packaging information is not specified. The E3FA-DP23 is supplied in bulk packaging. Connector type and physical dimensions should be verified for mechanical compatibility in the target application.

Q: Does the light source difference affect sensor performance?

A: Light source technology (Infrared 880nm versus Red LED) affects reflectivity characteristics and environmental performance. Red LED sensors may exhibit different performance with certain reflective materials or in high ambient light conditions. Application-specific testing is necessary to confirm suitability.

Q: What is the MSL rating for these sensors?

A: Both sensors carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.
