Key Parameters

Substitute Part Grouping Explanation

The T18-2VNRL-Q8 qualifies as a substitute for the T18SN6RQ based on the following critical parameters:

Matching Parameters:

• Sensing method: Both employ through-beam optical sensing technology
• Voltage supply range: Both operate within 10V ~ 30V
• Output configuration: Both provide NPN output with dark-ON/light-ON capability
• Connection method: Both use connector-based interfaces
• Ingress protection: Both meet NEMA 6P and IEC IP67 standards
• Operating temperature range: Both function across -40°C ~ 70°C
• Manufacturer: Both manufactured by Banner Engineering Corporation
• RoHS compliance: Both meet RoHS standards

Differentiation: The T18-2VNRL-Q8 represents an evolution within the Banner T18 sensor family, offering improved sensing distance (25m vs. 20m), faster response time (1ms/1.5ms vs. 3ms), and red LED light source instead of infrared. The substitute part is active in production, addressing the obsolescence of the original T18SN6RQ.

Engineering Selection Recommendations

The T18-2VNRL-Q8 is the designated substitute for the obsolete T18SN6RQ. Selection is supported by:

• Product Status Alignment: The substitute is active in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain RoHS compliance and REACH unaffected status, meeting current environmental and regulatory requirements
• Functional Equivalence: Identical voltage supply range, output configuration, and operating temperature specifications ensure direct functional compatibility in existing system designs
• Enhanced Performance: The substitute provides extended sensing distance (25m vs. 20m) and improved response time (1ms vs. 3ms), delivering performance advantages over the original part

Frequently Asked Questions (FAQ)

Q: Can the T18-2VNRL-Q8 directly replace the T18SN6RQ in existing installations?

A: Yes. Both sensors share identical voltage supply range (10V ~ 30V), NPN output configuration with dark-ON/light-ON capability, and operating temperature specifications (-40°C ~ 70°C). Connector-based interfaces on both parts support direct substitution. Verify connector compatibility with your specific installation before deployment.

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

A: The T18-2VNRL-Q8 is a newer generation sensor offering 25-meter sensing distance compared to the T18SN6RQ's 20-meter range, faster response time (1ms vs. 3ms), and red LED light source instead of infrared (950nm). The T18SN6RQ is obsolete; the T18-2VNRL-Q8 is actively manufactured.

Q: Are there packaging differences between these parts?

A: The T18SN6RQ packaging information is not specified in available documentation. The T18-2VNRL-Q8 is supplied in bulk packaging with M12 4-pin connector configuration.

Q: Do both sensors meet the same ingress protection standards?

A: Both meet NEMA 6P and IEC IP67 standards. The T18-2VNRL-Q8 additionally meets IEC IP68 and IEC IP69, providing enhanced protection in demanding environments.

Q: What compliance certifications apply to both sensors?

A: Both sensors are RoHS compliant and REACH unaffected. The T18SN6RQ carries ROHS3 compliance; the T18-2VNRL-Q8 carries RoHS compliance. Both are classified under ECCN EAR99.
