Substitute Part Grouping Explanation
Substitution eligibility for the CX-491-P-Y is determined by strict alignment across the following critical parameters:
Mandatory Matching Parameters:
- Sensing Method: Retroreflective
- Output Configuration: PNP - Open Collector
- Light Source: Red LED
- Voltage - Supply: 12V ~ 24V
- Response Time: 1ms
- Ingress Protection: IP67
- Operating Temperature: -25°C ~ 55°C
- Connection Method: Cable
- Cable Length: 196.85" (5m)
Allowable Variation:
- Sensing Distance: The CX-491-P-Y operates at 3m (118.110"). The substitute CX-491-P operates at 5m (16.40'), representing an extended detection range within the same sensor family. Extended range capability maintains backward compatibility for applications requiring shorter detection distances.
The CX-491-P qualifies as a direct substitute based on identical electrical characteristics, mechanical interface, environmental ratings, and response performance, with the distinction of increased sensing distance capability.

Engineering Selection Recommendations
The CX-491-P serves as the active production equivalent for the obsolete CX-491-P-Y. Both sensors share identical electrical specifications, mechanical interfaces, and environmental performance characteristics. The primary distinction is the extended sensing distance of the CX-491-P (5m versus 3m), which provides increased detection range capability without compromising any other functional parameter.
From a compliance perspective, the CX-491-P meets ROHS3 requirements, representing current regulatory standards, whereas the CX-491-P-Y meets RoHS Compliant specifications. The CX-491-P is currently in active production status with confirmed inventory availability (800 pcs), ensuring supply chain continuity for replacement and new system deployments.
For applications currently using the CX-491-P-Y, direct substitution with the CX-491-P is supported across all electrical, mechanical, and environmental operating conditions. The extended sensing distance of the CX-491-P does not introduce incompatibility; it expands the operational envelope of the sensor.
Frequently Asked Questions (FAQ)
Q: Can the CX-491-P directly replace the CX-491-P-Y in existing installations?
A: Yes. The CX-491-P is electrically and mechanically compatible with the CX-491-P-Y. Both sensors feature identical 12V-24V supply voltage, PNP open-collector output, 1ms response time, IP67 protection, and cable interface specifications. The extended 5m sensing distance of the CX-491-P does not create incompatibility with existing wiring or control logic.
Q: What is the primary difference between these two sensors?
A: The CX-491-P extends the sensing distance to 5m (16.40'), compared to the 3m (118.110") range of the CX-491-P-Y. All other electrical, mechanical, and environmental parameters remain identical. The CX-491-P is the active production model.
Q: Are there any compliance differences between the CX-491-P-Y and CX-491-P?
A: The CX-491-P-Y carries RoHS Compliant certification, while the CX-491-P carries ROHS3 Compliant certification. Both meet current regulatory requirements. The CX-491-P represents the current standard for new deployments.
Q: What is the cable length for both sensors?
A: Both the CX-491-P-Y and CX-491-P feature a 196.85" (5m) cable length with cable connection method.
Q: Is the CX-491-P-Y still available for purchase?
A: The CX-491-P-Y is classified as obsolete. The CX-491-P is the active production substitute with current inventory availability. For new system designs or replacements, the CX-491-P is the recommended selection.
Q: Do both sensors operate across the same temperature range?
A: Yes. Both the CX-491-P-Y and CX-491-P operate across -25°C to 55°C, ensuring compatibility across identical environmental conditions.
