Matching Parameters:

• Voltage supply range: 10V ~ 30V (identical)
• Output configuration: NPN - Dark-ON/Light-ON (identical)
• Connection method: Cable (identical)
• Cable length: 78.74" (2m) (identical)
• Operating temperature range: -40°C ~ 70°C (identical)
• Sensing method: Through-Beam (identical)
• RoHS and REACH compliance: ROHS3 Compliant, REACH Unaffected (identical)

Differing Parameters:

• Sensing distance: 82.02' (25m) vs. 787.402" (20m) — substitute provides extended range
• Response time: 1.5ms vs. 3ms — substitute offers faster response
• Light source: Red LED vs. Infrared (950nm) — different optical technology
• Ingress protection: IEC IP67, IEC IP68, IEC IP69K vs. NEMA 6P, IEC IP67, IEC IP69K — substitute includes IP68 rating
• Series designation: T18-2 vs. T18 — next-generation series

The T18-2VNRL-2M maintains electrical and mechanical compatibility while offering performance enhancements in sensing distance and response time.

Parameter Comparison

Engineering Selection Recommendations

The T18-2VNRL-2M is the designated substitute for the obsolete T18SN6R. Both components maintain identical voltage supply specifications (10V ~ 30V), output configuration (NPN - Dark-ON/Light-ON), and operating temperature range (-40°C ~ 70°C), ensuring direct electrical compatibility in existing circuit designs.

The substitute part carries Active product status with full ROHS3 compliance and REACH Unaffected designation, providing long-term availability and regulatory alignment. The T18-2VNRL-2M offers performance improvements including extended sensing distance (25m vs. 20m) and reduced response time (1.5ms vs. 3ms), making it suitable for applications requiring enhanced detection capability.

Both components utilize cable-based connections with identical 2-meter cable lengths, supporting straightforward mechanical integration. The substitute's ingress protection ratings (IEC IP67, IEC IP68, IEC IP69K) exceed the original specification, providing superior environmental sealing for demanding industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the T18-2VNRL-2M directly replace the T18SN6R in existing installations?

A: Yes. Both sensors share identical voltage supply range (10V ~ 30V), NPN output configuration with dark-ON/light-ON capability, cable connection method, and operating temperature specifications (-40°C ~ 70°C). Electrical and mechanical compatibility is maintained.

Q: What are the key differences between these two sensors?

A: The T18-2VNRL-2M provides extended sensing distance (25m vs. 20m), faster response time (1.5ms vs. 3ms), and uses Red LED light source instead of infrared (950nm). The substitute also includes IEC IP68 ingress protection rating in addition to IP67 and IP69K ratings.

Q: Why is the T18SN6R listed as obsolete?

A: The T18SN6R has reached end-of-life status. The T18-2VNRL-2M represents the current-generation equivalent within Banner Engineering Corporation's T18 sensor product line.

Q: Are there any compliance differences between the two parts?

A: No. Both components are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for industrial applications.

Q: Does the different light source (Red LED vs. Infrared) affect compatibility?

A: The light source difference does not affect electrical compatibility. However, optical performance characteristics may vary depending on the specific application environment and target material reflectivity. Both sensors maintain the same NPN output configuration and switching logic.

Q: Is the 2-meter cable length identical on both sensors?

A: Yes. Both the T18SN6R and T18-2VNRL-2M feature 78.74" (2m) cable lengths, supporting identical installation configurations.
