Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the EE-SX911P-R 1M is determined by the following critical parameters:

• Sensing Method: Through-beam detection capability
• Sensing Distance: 0.197" (5mm) detection range
• Output Configuration: PNP logic level output
• Package Type: Module format with wire leads and slot-type mechanical interface
• Mounting Type: Chassis mount compatibility
• Operating Temperature Range: -25°C to 55°C operational envelope
• Sensor Type: Amplified optical sensor

The substitute part EE-SX951P-R 1M maintains all critical parameters required for functional equivalence. While the output configuration differs in selectable dark-ON/light-ON functionality compared to the fixed open-collector output of the original part, the electrical interface remains PNP-compatible, and the mechanical and environmental specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The EE-SX951P-R 1M is the direct substitute for the obsolete EE-SX911P-R 1M. Selection of this substitute is supported by the following factors:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity.
• Functional Equivalence: Both sensors share identical sensing distance, through-beam detection method, and mechanical form factor.
• Electrical Compatibility: Both parts feature PNP output configuration suitable for integration into existing control circuits.
• Compliance: The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Environmental Specifications: Identical operating temperature range ensures compatibility with existing thermal design parameters.

The selectable dark-ON/light-ON output configuration of the substitute part provides enhanced flexibility compared to the fixed open-collector output of the original part, without compromising backward compatibility in standard through-beam detection applications.

Frequently Asked Questions (FAQ)

Q: Can the EE-SX951P-R 1M directly replace the EE-SX911P-R 1M in existing installations?

A: Yes. Both sensors share identical sensing distance (0.197" / 5mm), through-beam detection method, PNP output logic, chassis mount configuration, and module package type with wire leads. The mechanical and electrical interfaces are compatible.

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

A: The EE-SX911P-R 1M features fixed open-collector PNP output, while the EE-SX951P-R 1M provides selectable dark-ON/light-ON output configuration. Both maintain PNP logic compatibility.

Q: Why is the EE-SX911P-R 1M listed as obsolete?

A: The original part has been discontinued by the manufacturer. The EE-SX951P-R 1M represents the current active product line for equivalent through-beam slot-type optical sensing at 5mm detection distance.

Q: Are there any electrical parameter differences that affect circuit design?

A: The substitute part specifies maximum collector current (15 mA) and collector-emitter breakdown voltage (24 V). These parameters should be verified against the original circuit design to ensure compatibility with existing load resistances and supply voltages.

Q: Is the substitute part compliant with current environmental regulations?

A: Yes. The EE-SX951P-R 1M is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Are the wire lead configurations identical between both parts?

A: Both sensors are packaged as modules with wire leads in slot-type configuration. Verification of specific lead assignments and connector compatibility with existing harnesses is recommended during integration.
