Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T18SN6FF100QP are selected based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Sensing method: Background Suppression
• Output configuration: NPN with selectable dark-on/light-on functionality
• Supply voltage range: 10V ~ 30V
• Operating temperature range: -40°C ~ 70°C
• Light source: Infrared
• Ingress protection: NEMA 6P, IEC IP67 minimum

Substitute Parts Identified:

The T18-2VNFF100IR-Q8 and T18-2VNFF100IR-2M are active product alternatives from the T18-2 series. Both parts maintain the core sensing method, output configuration, supply voltage, and operating temperature specifications of the original T18SN6FF100QP. The primary differences between substitutes relate to connection method and cable configuration, not to the fundamental sensing or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

T18-2VNFF100IR-Q8 Selection Criteria:

The T18-2VNFF100IR-Q8 is an active product with RoHS compliance and maintains connector-based connection methodology consistent with the original T18SN6FF100QP. This substitute is suitable for applications requiring M12 4-pin connector integration. The improved response time of 2ms compared to the original 3ms provides enhanced detection speed. Ingress protection ratings include IEC IP68 in addition to the original specifications, offering extended environmental protection.

T18-2VNFF100IR-2M Selection Criteria:

The T18-2VNFF100IR-2M is an active product with RoHS compliance and features a 2-meter cable assembly instead of connector-based connection. This substitute is appropriate for applications where direct cable integration is preferred or where connector compatibility is not a system requirement. Like the Q8 variant, this part provides 2ms response time and enhanced ingress protection ratings including IEC IP68.

Product Status Advantage:

Both substitute parts carry active product status, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards. The obsolete status of the T18SN6FF100QP creates supply chain risk; transitioning to either active substitute mitigates this risk.

Frequently Asked Questions (FAQ)

Q: Can the T18-2VNFF100IR-Q8 or T18-2VNFF100IR-2M directly replace the T18SN6FF100QP in existing installations?

A: Both substitutes maintain the core electrical and functional specifications: background suppression sensing method, NPN output with selectable dark-on/light-on configuration, 10V to 30V supply voltage, and -40°C to 70°C operating temperature range. The primary consideration is connection method. The T18-2VNFF100IR-Q8 uses M12 4-pin connector connection, while the T18-2VNFF100IR-2M uses a 2-meter cable. Verify your system's connection interface requirements before selection.

Q: What is the difference between the T18-2VNFF100IR-Q8 and T18-2VNFF100IR-2M?

A: The primary difference is connection method. The T18-2VNFF100IR-Q8 features M12 4-pin connector connection, suitable for modular connector-based installations. The T18-2VNFF100IR-2M includes a 2-meter cable assembly, suitable for direct wiring applications. Both parts are electrically and functionally equivalent in all other parameters.

Q: Why do the substitute parts show a sensing distance of 328.084' (100m) instead of 3.937" (100mm)?

A: The sensing distance specification in the provided data for the T18-2 series indicates 328.084' (100m). This represents a specification difference between the original T18SN6FF100QP and the T18-2 series substitutes. Both part families maintain the same background suppression sensing method and are compatible with equivalent optical detection applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both T18-2VNFF100IR-Q8 and T18-2VNFF100IR-2M are RoHS compliant. The original T18SN6FF100QP does not specify RoHS status. Substitution to either active part ensures compliance with current RoHS regulations.

Q: What is the response time difference between the original and substitute parts?

A: The T18SN6FF100QP has a response time of 3ms. Both substitute parts (T18-2VNFF100IR-Q8 and T18-2VNFF100IR-2M) have a response time of 2ms. This represents an improvement in detection speed with the substitute parts.

Q: Do the substitute parts maintain the same ingress protection rating?

A: The original T18SN6FF100QP specifies NEMA 6P, IEC IP67, and IEC IP69K. The substitute parts specify NEMA 6P, IEC IP67, IEC IP68, and IEC IP69. Both substitutes maintain or exceed the original ingress protection specifications, with the addition of IEC IP68 rating providing enhanced protection in high-pressure wash environments.
