CX-443-P-Z Equivalent & Substitute Parts

Part Overview

The CX-443-P-Z is a reflective optical sensor manufactured by Panasonic Industrial Automation Sales, designed for proximity detection applications with a sensing distance of 0.079" to 1.969" (2mm to 50mm). This component features PNP open-collector output, operates across 12V to 24V supply voltage, and is housed in an M8 4-position connector configuration with IP67 ingress protection rating.

The CX-443-P-Z is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new design implementations where this sensing distance range is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CX-443-P-Z is determined by the following critical parameters:

• Sensing Method: Must be reflective to maintain functional equivalence
• Output Configuration: Must be PNP - Open Collector to ensure circuit compatibility
• Voltage - Supply: Must support 12V ~ 24V operating range
• Connection Method: Must use M8 4-position connector for mechanical and electrical compatibility
• Light Source: Must be Red LED to maintain optical characteristics
• Ingress Protection: Must maintain IP67 rating for environmental sealing
• Response Time: Must be 1ms or faster to preserve system timing requirements
• Operating Temperature: Must support -25°C ~ 55°C range

The CX-444-P-Z qualifies as a substitute part because it maintains all critical parameters while extending the sensing distance range to 0.591" ~ 3.937" (15mm ~ 100mm). This extended range does not compromise compatibility in applications where the original 2mm ~ 50mm range is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The CX-444-P-Z is the designated substitute for the obsolete CX-443-P-Z. Both components share identical electrical and mechanical specifications across all critical parameters: reflective sensing method, PNP open-collector output, 12V ~ 24V supply voltage, M8 4-position connector, IP67 protection, 1ms response time, and -25°C ~ 55°C operating temperature range.

The CX-444-P-Z maintains active product status, ensuring ongoing availability and supply chain continuity. The component carries ROHS3 compliance, meeting current regulatory requirements. The extended sensing distance range of the CX-444-P-Z (15mm ~ 100mm versus 2mm ~ 50mm) provides additional operational flexibility without introducing incompatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the CX-444-P-Z directly replace the CX-443-P-Z in existing installations?

A: Yes. Both components share identical electrical output configuration (PNP - Open Collector), supply voltage range (12V ~ 24V), connector type (M8 4-position), and environmental ratings (IP67). The extended sensing distance range of the CX-444-P-Z does not create incompatibility.

Q: What is the primary difference between these two models?

A: The sensing distance range differs. The CX-443-P-Z operates from 2mm to 50mm, while the CX-444-P-Z operates from 15mm to 100mm. All other functional and mechanical parameters are identical.

Q: Why is the CX-443-P-Z classified as obsolete?

A: The CX-443-P-Z has been discontinued by the manufacturer. The CX-444-P-Z is the active replacement model within the CX-400 series.

Q: Are there packaging differences between these models?

A: The CX-444-P-Z is supplied in Box packaging. Packaging specifications for the CX-443-P-Z were not provided in the technical data.

Q: Do both models meet current compliance standards?

A: The CX-443-P-Z is RoHS Compliant. The CX-444-P-Z is ROHS3 Compliant, meeting current regulatory requirements.
