T18SP6R Equivalent & Substitute Parts

Part Overview

The T18SP6R is a through-beam optical sensor manufactured by Banner Engineering Corporation, designed for long-range detection applications up to 787.402" (20m). This sensor operates with PNP output configuration supporting both Dark-ON and Light-ON modes, utilizing infrared light source at 950nm wavelength. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the T18SP6R is determined by the following critical parameters that must remain consistent or be compatible with the original application:

Core Compatibility Criteria:

• Sensing method: Through-beam operation
• Output configuration: PNP with Dark-ON/Light-ON capability
• Voltage supply range: 10V ~ 30V
• Connection method: Cable-based interface
• Operating temperature range: -40°C ~ 70°C minimum
• Ingress protection: Minimum IEC IP67 rating
• RoHS and REACH compliance status

Allowable Variations:

• Sensing distance may increase (longer range acceptable)
• Response time may decrease (faster response acceptable)
• Light source type may differ (infrared or red LED acceptable)
• Ingress protection rating may exceed minimum requirement
• Cable length remains at 78.74" (2m)

The T18-2VPRL-2M qualifies as a substitute based on these criteria, despite differences in sensing distance and light source technology.

Parameter Comparison

Engineering Selection Recommendations

The T18-2VPRL-2M serves as the direct substitute for the obsolete T18SP6R based on functional equivalence and regulatory compliance alignment.

Selection Basis:

Both sensors maintain identical voltage supply specifications (10V ~ 30V), output configuration (PNP Dark-ON/Light-ON), and operating temperature range (-40°C ~ 70°C). The T18-2VPRL-2M is currently in active production status, ensuring long-term availability and supply chain continuity.

The substitute provides enhanced specifications in three areas: extended sensing distance (25m versus 20m), improved response time (1.5ms versus 3ms), and superior ingress protection rating (IEC IP68 addition). These enhancements represent performance improvements without introducing compatibility issues in applications designed for the original T18SP6R.

Both components maintain identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution. Cable length and connection methodology remain unchanged at 78.74" (2m) cable interface.

The shift from infrared (950nm) to red LED light source in the T18-2VPRL-2M represents a technology evolution within the Banner T18 series. This change does not compromise functional compatibility in through-beam sensing applications, as both wavelengths operate within standard optical sensor detection parameters.

Frequently Asked Questions (FAQ)

Q: Can the T18-2VPRL-2M directly replace the T18SP6R in existing installations?

A: Yes. Both sensors share identical voltage supply range (10V ~ 30V), PNP output configuration with Dark-ON/Light-ON modes, cable connection method, and operating temperature specifications (-40°C ~ 70°C). Electrical and mechanical interfaces are compatible.

Q: What is the significance of the extended sensing distance in the T18-2VPRL-2M?

A: The T18-2VPRL-2M provides 25m sensing capability compared to the T18SP6R's 20m range. This represents an enhancement that does not restrict compatibility. Applications requiring the original 20m range will function without modification.

Q: Does the light source change from infrared to red LED affect compatibility?

A: No. Both infrared (950nm) and red LED light sources operate within standard through-beam optical sensor detection parameters. The change represents technology evolution within the Banner T18 series and does not impact functional compatibility in through-beam applications.

Q: Why is the T18SP6R classified as obsolete?

A: Product obsolescence reflects Banner Engineering Corporation's product lifecycle management. The T18-2VPRL-2M represents the current-generation equivalent within the T18 series, offering improved specifications while maintaining functional compatibility.

Q: Are there packaging differences between these sensors?

A: The T18SP6R packaging information is not specified in available documentation. The T18-2VPRL-2M is supplied in box packaging. Both sensors utilize identical cable connection methodology and 78.74" (2m) cable length.

Q: Do both sensors meet the same regulatory compliance standards?

A: Yes. Both the T18SP6R and T18-2VPRL-2M are ROHS3 compliant and REACH unaffected. Regulatory compliance alignment supports direct substitution for applications with compliance requirements.

Q: What is the inventory status for these components?

A: The T18SP6R has 857 pieces available as new original stock. The T18-2VPRL-2M has 1053 pieces available as new original stock. Both components are currently in inventory.
