Key Parameters

Substitute Part Grouping Explanation

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

• Sensing method: Retroreflective
• Sensing distance: 16.40' (5m)
• Voltage supply range: 12V ~ 24V
• Output configuration: NPN - Open Collector
• Light source: Red LED
• Connection method: Connector, M8, 4POS
• Ingress protection: IP67
• Operating temperature range: -25°C ~ 55°C

The CX-491-Z is identified as a direct substitute. Both parts belong to the CX-400 series and maintain identical electrical and mechanical specifications. The primary distinction is product status: CX-491-Z-Y is obsolete while CX-491-Z is active.

Parameter Comparison

Engineering Selection Recommendations

The CX-491-Z is the direct equivalent for the obsolete CX-491-Z-Y. Both parts maintain identical electrical performance and mechanical compatibility. The CX-491-Z is currently in active production status with 946 units in stock, ensuring availability for replacement and new applications.

The CX-491-Z carries ROHS3 compliance, representing an enhanced regulatory status compared to the RoHS compliance of the CX-491-Z-Y. This upgrade reflects current environmental and safety standards without altering the functional specifications of the sensor.

For applications currently using CX-491-Z-Y, direct substitution with CX-491-Z is appropriate. No circuit modifications, firmware updates, or mechanical redesign is required.

Frequently Asked Questions (FAQ)

Q: Can CX-491-Z replace CX-491-Z-Y in existing installations?
