Substitute Part Grouping Explanation

Substitution of the T18SP6RQP is based on alignment of critical electrical and mechanical parameters across the T18 series optical sensor family. The substitute parts T18-2VPRL-Q8 and T18-2VPRL-2M are members of the T18-2 series, representing active product variants that maintain compatibility with the original design through the following key parameters:

Electrical Compatibility:

• Supply voltage range: 10V ~ 30V (identical)
• Output configuration: PNP - Dark-ON/Light-ON (identical)
• Operating temperature: -40°C ~ 70°C (identical)

Mechanical & Environmental Compatibility:

• Sensing method: Through-Beam (identical)
• Ingress protection: IEC IP67, IEC IP68, IEC IP69K (exceeds original specification)
• Moisture sensitivity level: 1 (Unlimited) (identical)

Functional Enhancement:

• Sensing distance: 82.02' (25m) versus 787.402" (20m) (extended range)
• Response time: 1.5ms (improved from 3ms option)
• Product status: Active (ensures ongoing availability)

The T18-2VPRL-Q8 and T18-2VPRL-2M differ in connection method and cable configuration, allowing selection based on installation requirements.

Parameter Comparison

Engineering Selection Recommendations

T18-2VPRL-Q8 Selection Criteria: The T18-2VPRL-Q8 is an active product with connector-based connection method, matching the original T18SP6RQP interface type. This variant provides extended sensing distance of 82.02' (25m) compared to the original 787.402" (20m), enhanced ingress protection rating to IEC IP68 and IEC IP69K, and improved response time of 1.5ms. The product holds ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with current environmental standards. Selection of this variant is appropriate for applications requiring connector-based installation with no fixed cable length requirement.

T18-2VPRL-2M Selection Criteria: The T18-2VPRL-2M is an active product with integrated 78.74" (2m) cable, directly matching the cable length specification of the original T18SP6RQP. This variant provides identical sensing distance extension to 82.02' (25m) and response time improvement to 1.5ms, with equivalent ingress protection and regulatory compliance. Selection of this variant is appropriate for applications requiring direct cable connection with fixed 2-meter cable length, eliminating the need for separate connector assembly.

Both substitute parts represent active products from Banner Engineering Corporation, ensuring long-term availability and support compared to the obsolete T18SP6RQP.

Frequently Asked Questions (FAQ)

Q: Can the T18-2VPRL-Q8 and T18-2VPRL-2M be used interchangeably with the T18SP6RQP?

A: Both T18-2 series sensors maintain electrical compatibility through identical supply voltage range (10V ~ 30V), output configuration (PNP - Dark-ON/Light-ON), and operating temperature (-40°C ~ 70°C). The primary difference is connection method: T18-2VPRL-Q8 uses a connector interface, while T18-2VPRL-2M includes an integrated 2-meter cable. Selection depends on the installation's connection requirements.

Q: What is the difference between the light sources in these sensors?

A: The original T18SP6RQP uses infrared light at 950nm, while both T18-2 series substitutes use red LED light sources. Both are through-beam optical sensors with identical sensing methods and compatible electrical specifications. The light source difference does not affect electrical compatibility or output behavior.

Q: Does the increased sensing distance of the T18-2 series affect compatibility?

A: The T18-2VPRL-Q8 and T18-2VPRL-2M provide extended sensing distance of 82.02' (25m) compared to the original 787.402" (20m). This represents an enhancement that does not compromise compatibility. Applications requiring the original 20-meter range will function correctly with the extended-range substitutes.

Q: Are there any compliance differences between the original and substitute parts?

A: The original T18SP6RQP holds RoHS Compliant status, while both T18-2 series substitutes hold ROHS3 Compliant status, representing an updated compliance standard. All three parts maintain REACH Unaffected status. The substitute parts meet or exceed the regulatory requirements of the original.

Q: Which substitute should be selected for a connector-based installation?

A: The T18-2VPRL-Q8 is designed for connector-based connection and does not include a fixed cable length. This variant is appropriate for installations where the sensor connects via a connector interface without a pre-attached cable.

Q: Which substitute should be selected for a direct cable installation?

A: The T18-2VPRL-2M includes an integrated 78.74" (2m) cable, matching the cable length of the original T18SP6RQP. This variant is appropriate for installations requiring direct cable connection without separate connector assembly.

Q: What is the ingress protection rating difference?

A: The original T18SP6RQP specifies NEMA 6P, IEC IP67, and IEC IP69. Both T18-2 series substitutes specify IEC IP67, IEC IP68, and IEC IP69K, providing enhanced protection ratings that exceed the original specification.
