Key Parameters

Substitute Part Grouping Explanation

Substitution of the KT5W-2P1123 is determined by the following critical parameters:

• Output Configuration: PNP output capability is required for direct replacement
• Light Source: RGB LED technology must be maintained
• Connection Method: M12 connector interface for mechanical compatibility
• Ingress Protection: IP67 rating for environmental sealing
• Voltage Supply Range: Compatibility within 10V ~ 30V operating window
• Sensing Distance: Functional range for contrast detection application

The substitute parts 1078066 and 1078097 maintain PNP output with Dark-ON/Light-ON capability and RGB LED light source. Part 1078122 offers Push-Pull output (NPN/PNP selectable), providing broader output configuration flexibility. All three substitutes operate within compatible voltage ranges, maintain IP67 protection, and use M12 connectors. The sensing distance increases to 0.512" (13mm) across all substitutes, representing an enhanced detection range compared to the original 10mm specification.

Parameter Comparison

Engineering Selection Recommendations

Parts 1078066 and 1078097 are direct functional equivalents for PNP-only applications. Both are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. These parts feature improved response time (10µs versus 50µs) and extended operating temperature range (-20°C ~ 60°C). The increased sensing distance (13mm versus 10mm) provides enhanced detection capability. Inventory availability is confirmed at 806 and 782 units respectively.

Part 1078122 offers expanded output flexibility with Push-Pull configuration supporting both NPN and PNP modes. This part is classified within the KTS Prime series and is active with confirmed inventory of 1030 units. The Push-Pull output enables integration into systems requiring either NPN or PNP logic without additional interface components.

All three substitutes maintain RGB LED light source technology, M12 connector interface, and IP67 environmental protection rating. Selection between 1078066/1078097 and 1078122 depends on output configuration requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can 1078066 or 1078097 directly replace KT5W-2P1123 in existing installations?

A: Yes, for applications requiring PNP output. Both parts maintain PNP Dark-ON/Light-ON capability, RGB LED light source, M12 connector interface, and IP67 protection. The increased sensing distance (13mm versus 10mm) and improved response time (10µs versus 50µs) represent performance enhancements. Voltage supply ranges are compatible within the 10.8V ~ 28.8V window.

Q: What is the difference between 1078066 and 1078097?

A: Both parts share identical electrical and mechanical specifications. The distinction lies in packaging: 1078066 is supplied in Box packaging, while 1078097 is also supplied in Box packaging. Both include 196.85" (5m) cable length and adjustable sensing distance. Inventory levels differ slightly (806 versus 782 units).

Q: When should 1078122 be selected instead of 1078066 or 1078097?

A: Select 1078122 when the application requires output flexibility. This part offers Push-Pull configuration with selectable NPN/PNP output, enabling integration into systems designed for either logic type without additional interface circuitry. Part 1078122 is supplied in Bulk packaging and does not include cable length specification.

Q: Are there compatibility concerns with the increased sensing distance?

A: The sensing distance increase from 10mm to 13mm represents an extended detection range. Applications must accommodate this increased range within their mechanical and optical design. The contrast detection principle remains unchanged across all substitute parts.

Q: What compliance certifications apply to the substitute parts?

A: Parts 1078066 and 1078097 are ROHS3 compliant and REACH unaffected. Part 1078122 compliance information is not specified in the provided data. All three parts maintain IP67 ingress protection rating.
