Key Parameters

Substitute Part Grouping Explanation

Substitution of the CX-491B-P-C05-Y is determined by strict equivalence across the following critical parameters:

• Sensing method (retroreflective)
• Sensing distance (16.40' / 5m)
• Supply voltage range (12V ~ 24V)
• Output configuration (PNP - Open Collector)
• Response time (1ms)
• Light source (Red LED)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C ~ 55°C)
• Series classification (CX-400)

The CX-491-P qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in cable length and packaging do not affect functional compatibility in applications where the CX-491B-P-C05-Y was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The CX-491-P is the appropriate substitute for the obsolete CX-491B-P-C05-Y. Both components share identical electrical specifications, sensing characteristics, and environmental ratings. The CX-491-P maintains active product status with current manufacturing and inventory availability (800 Pcs in stock versus 686 Pcs for the obsolete variant).

The primary difference is cable length: the CX-491B-P-C05-Y provides 19.5" (50cm) cable, while the CX-491-P provides 196.85" (5m) cable. This difference does not affect electrical compatibility or functional performance. The CX-491-P also carries ROHS3 compliance, representing current regulatory alignment.

Both components are classified under ECCN EAR99 and HTSUS 8541.49.8000, with identical moisture sensitivity levels (MSL 1 - Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the CX-491-P directly replace the CX-491B-P-C05-Y in existing installations?

A: Yes. Both sensors share identical electrical specifications, sensing distance, supply voltage, output configuration, response time, and environmental ratings. Functional compatibility is confirmed across all critical parameters.

Q: What is the significance of the different cable lengths?

A: The CX-491B-P-C05-Y includes 19.5" (50cm) cable, while the CX-491-P includes 196.85" (5m) cable. Cable length does not affect sensor operation or electrical compatibility. Installation requirements should determine whether the longer cable of the CX-491-P is suitable for your application.

Q: Why is the CX-491B-P-C05-Y listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The CX-491-P remains in active production and is the current equivalent offering from Panasonic Industrial Automation Sales.

Q: Are there compliance differences between these parts?

A: Both components are RoHS compliant. The CX-491-P carries ROHS3 certification, representing alignment with current regulatory standards. Both share identical ECCN and HTSUS classifications.

Q: What packaging differences exist between these parts?

A: The CX-491B-P-C05-Y packaging is unspecified in available data. The CX-491-P is supplied in Box packaging. Packaging does not affect electrical or functional compatibility.
