KT5G-2P1111 Equivalent & Substitute Parts

Part Overview

The KT5G-2P1111 is an optical sensor manufactured by SICK, Inc., designed for contrast detection applications with a 10mm sensing distance. This PNP-configured sensor features selectable Dark-ON/Light-ON output modes and operates across a 10V to 30V supply range. The product is currently classified as obsolete, necessitating identification of active alternative components that maintain functional compatibility for existing applications.

Substitute Part Grouping Explanation

Substitution of the KT5G-2P1111 is determined by the following critical parameters: sensing distance, output configuration, supply voltage range, connection method (M12), ingress protection rating (IP67), and operating temperature range. The substitute parts identified maintain M12 connector compatibility and IP67 environmental sealing. However, substitute components feature increased sensing distances (0.512" / 13mm versus 10mm) and modified output configurations. The KT5G-2P1111 specifies PNP output with selectable Dark-ON/Light-ON modes; substitute parts offer either Push-Pull (NPN/PNP) or fixed PNP configurations. Supply voltage ranges and operating temperatures are comparable across all identified alternatives, with substitutes offering improved response times and extended temperature operating ranges.

Engineering Selection Recommendations

All identified substitute parts are classified as active products with current manufacturing status, providing supply chain continuity for applications currently using the obsolete KT5G-2P1111. The KTS-WB41141142 and 1078119 are compliant with ROHS3 and REACH standards where applicable. The KTX-WP91141242 and KTX-WP91142242 are both ROHS3 compliant and REACH unaffected, representing the KTX Prime series with enhanced response times of 10µs compared to the original 50µs specification.

Selection between substitute options depends on output configuration requirements. The 1078119 and KTS-WB41141142 provide Push-Pull output supporting both NPN and PNP modes, offering flexibility for existing circuit designs. The KTX-WP91141242 and KTX-WP91142242 provide fixed PNP output, directly compatible with the original PNP configuration of the KT5G-2P1111.

All substitutes operate within comparable supply voltage ranges and maintain M12 connector compatibility with IP67 environmental protection. The increased sensing distance of 13mm in substitute parts represents a functional change that must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the KT5G-2P1111 be directly replaced with any of these substitute parts?

A: Direct replacement requires evaluation of sensing distance tolerance. The KT5G-2P1111 operates at 10mm sensing distance, while all identified substitutes operate at 13mm. Applications with fixed target distances must confirm that the 3mm increase is acceptable. Output configuration compatibility must also be verified: the KTX-WP91141242 and KTX-WP91142242 maintain PNP output matching the original, while 1078119 and KTS-WB41141142 offer Push-Pull output requiring circuit adaptation.

Q: What are the key differences in output configuration between substitute options?

A: The KT5G-2P1111 provides PNP output with selectable Dark-ON/Light-ON modes. The 1078119 and KTS-WB41141142 provide Push-Pull output supporting both NPN and PNP operation, requiring configuration selection. The KTX-WP91141242 and KTX-WP91142242 provide fixed PNP output without selectable modes, matching the original output type but with reduced configurability.

Q: Are all substitute parts compatible with the original M12 connector?

A: All substitute parts feature M12 connectors maintaining physical compatibility. The original KT5G-2P1111 specifies M12 4-position connectors; substitute parts specify M12 connectors without position specification. Connector pin configuration must be verified during integration.

Q: What is the impact of the improved response time in substitute parts?

A: Substitute parts KTX-WP91141242 and KTX-WP91142242 provide 10µs response time compared to the original 50µs specification. The 1078119 and KTS-WB41141142 provide 20µs response time. Faster response times represent functional improvements suitable for applications requiring higher detection speeds.

Q: Do substitute parts maintain the same operating temperature range?

A: The KT5G-2P1111 operates across -10°C to 55°C. All substitute parts extend this range to -20°C to 60°C, providing broader environmental operating capability.
