T18SN6LPQ Equivalent & Substitute Parts

Part Overview

The T18SN6LPQ is a retroreflective, polarized optical sensor manufactured by Banner Engineering Corporation, designed for 2-meter sensing distance applications with NPN output configuration. This sensor operates across a 10V to 30V supply voltage range and features dark-ON/light-ON switching capability with a 3ms response time. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T18SN6LPQ is determined by the following critical parameters:

• Sensing method: Retroreflective, polarized technology
• Output configuration: NPN with dark-ON/light-ON capability
• Supply voltage range: 10V ~ 30V compatibility
• Operating temperature range: -40°C ~ 70°C
• Ingress protection rating: NEMA 6P, IP69K minimum
• Connection method: Connector-based interface
• RoHS and regulatory compliance: ROHS3 compliant, EAR99 classification

The T18-2VNLP-Q8 qualifies as a direct substitute based on these parameters. While the substitute part offers extended sensing distance (6m versus 2m) and improved response time (1.5ms versus 3ms), these represent functional enhancements rather than deviations from the core substitution criteria. Both sensors maintain identical supply voltage ranges, operating temperature specifications, ingress protection ratings, and connector-based connection methods.

Parameter Comparison

Engineering Selection Recommendations

The T18-2VNLP-Q8 is the designated substitute for the obsolete T18SN6LPQ. Both components maintain ROHS3 compliance and EAR99 classification, ensuring regulatory alignment across replacement scenarios. The substitute part carries active product status, providing long-term availability and supply chain stability compared to the obsolete main part.

The T18-2VNLP-Q8 operates within identical electrical parameters (10V ~ 30V supply, -40°C ~ 70°C operating range) and maintains equivalent ingress protection ratings. The substitute's extended sensing distance (6m versus 2m) and faster response time (1.5ms versus 3ms) represent performance improvements that do not compromise backward compatibility in applications originally designed for the T18SN6LPQ.

Frequently Asked Questions (FAQ)

Q: Can the T18-2VNLP-Q8 directly replace the T18SN6LPQ in existing installations?

A: Yes. Both sensors share identical supply voltage ranges (10V ~ 30V), operating temperature specifications (-40°C ~ 70°C), ingress protection ratings (NEMA 6P, IP69K), and connector-based interfaces. The substitute's enhanced sensing distance and response time do not introduce compatibility issues.

Q: What is the primary reason for substitution?

A: The T18SN6LPQ is classified as obsolete. The T18-2VNLP-Q8 is an active product from the same manufacturer, ensuring continued availability and support.

Q: Are there differences in output configuration between these sensors?

A: Both sensors provide NPN output with dark-ON/light-ON capability. The T18-2VNLP-Q8 offers selectable output configuration, providing additional operational flexibility beyond the fixed configuration of the T18SN6LPQ.

Q: How do the light source wavelengths compare?

A: The T18SN6LPQ operates at 680nm (red), while the T18-2VNLP-Q8 operates at 624nm (red). Both wavelengths fall within the red spectrum and maintain retroreflective, polarized sensing methodology.

Q: What packaging considerations apply to the T18-2VNLP-Q8?

A: The T18-2VNLP-Q8 is supplied in box packaging. Connector-based interface compatibility remains consistent with the main part.

Q: Are both sensors RoHS compliant?

A: Yes. Both the T18SN6LPQ and T18-2VNLP-Q8 are ROHS3 compliant and classified as EAR99 for export control purposes.
