CX-443-Z Equivalent & Substitute Parts

Part Overview

The CX-443-Z is a reflective optical sensor manufactured by Panasonic Industrial Automation Sales, designed for proximity detection applications requiring sensing distances between 0.079" and 1.969" (2mm to 50mm). This sensor features NPN open collector output, operates across 12V to 24V supply voltage, and meets IP67 ingress protection requirements for industrial environments.

The CX-443-Z is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support ongoing maintenance and replacement requirements for existing installations.

Key Parameters

Substitute Part Grouping Explanation

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

• Sensing Method: Must be reflective to maintain functional equivalence
• Output Configuration: Must be NPN - Open Collector for circuit compatibility
• Voltage Supply Range: Must support 12V ~ 24V operation
• Connection Method: Must use M8 4-position connector for mechanical compatibility
• Ingress Protection: Must maintain IP67 rating for environmental sealing
• Light Source: Must use Red LED for optical wavelength consistency
• Response Time: Must match or exceed 1ms performance specification
• Operating Temperature Range: Must support -25°C ~ 55°C minimum

The CX-444-Z qualifies as a substitute part. While its sensing distance range extends to 3.937" (100mm) compared to the CX-443-Z maximum of 1.969" (50mm), all critical electrical, mechanical, and environmental parameters remain identical. The extended sensing distance of the CX-444-Z does not compromise compatibility in applications requiring shorter detection ranges, as the sensor will function within the CX-443-Z's specified distance parameters.

Parameter Comparison

Engineering Selection Recommendations

The CX-444-Z is the qualified substitute for the obsolete CX-443-Z. Both components maintain identical electrical specifications, mechanical interfaces, and environmental ratings. The CX-444-Z is currently in active production status with confirmed inventory availability, ensuring supply chain reliability for replacement and new installations.

The extended sensing distance range of the CX-444-Z (15mm ~ 100mm versus 2mm ~ 50mm) does not introduce incompatibility. Applications utilizing the CX-443-Z within its original 2mm to 50mm detection window will operate identically with the CX-444-Z, as the substitute sensor functions across the full range of the original part's specifications.

Both components carry RoHS compliance certification and identical ECCN and HTSUS classifications, supporting regulatory and procurement requirements without modification.

Frequently Asked Questions (FAQ)

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

A: Yes. The CX-444-Z maintains identical electrical output configuration (NPN - Open Collector), supply voltage range (12V ~ 24V), connector type (M8 4-position), and environmental protection (IP67). Direct mechanical and electrical substitution is supported.

Q: What is the significance of the extended sensing distance in the CX-444-Z?

A: The CX-444-Z sensing range extends from 15mm to 100mm, compared to the CX-443-Z range of 2mm to 50mm. This extended capability does not affect compatibility. Applications requiring detection within the original 2mm to 50mm window will function identically with the substitute part.

Q: Are there packaging differences between the CX-443-Z and CX-444-Z?

A: The CX-443-Z packaging specification is not provided in the technical data. The CX-444-Z is supplied in box packaging. Confirm packaging requirements with your procurement or logistics department if specific packaging standards apply to your application.

Q: Do both sensors use the same optical wavelength?

A: Yes. Both the CX-443-Z and CX-444-Z utilize Red LED light sources, ensuring consistent optical performance and reflective target compatibility.

Q: What is the operational temperature range for both sensors?

A: Both sensors operate across -25°C to 55°C, supporting industrial environments with identical thermal performance specifications.
