CY-11A Equivalent & Substitute Parts

Part Overview

The CY-11A is a through-beam optical sensor manufactured by Panasonic Industrial Automation Sales, designed for long-range detection applications with a sensing distance of 472.4" (12m). This sensor operates across a wide voltage range (24V ~ 240V) and features light-on output configuration with infrared light source and IP67 ingress protection. The CY-11A is classified as obsolete, making identification of compatible substitute parts essential for system maintenance and new installations where this model is no longer available.

Key Parameters

Substitute Part Grouping Explanation

The NX5-M30A qualifies as a substitute for the CY-11A based on the following critical parameters:

Functional Compatibility Parameters:

• Sensing Method: Both employ through-beam detection
• Output Configuration: Both feature light-on output
• Light Source: Both use infrared
• Connection Method: Both use cable connection

Electrical Compatibility Parameters:

• Voltage Supply: NX5-M30A supports 12V ~ 240V and 24V ~ 240V, which encompasses the CY-11A requirement of 24V ~ 240V
• Response Time: NX5-M30A at 10ms is faster than CY-11A at 20ms, providing equal or superior performance

Environmental & Mechanical Compatibility:

• Ingress Protection: NX5-M30A provides IP66, which is comparable to CY-11A IP67 for most industrial applications
• Operating Temperature: NX5-M30A range of -20°C ~ 55°C overlaps with CY-11A range of -25°C ~ 55°C
• RoHS Compliance: NX5-M30A is ROHS3 compliant, meeting modern regulatory requirements

Sensing Distance Consideration: The NX5-M30A offers 1181.1" (30m) sensing distance, exceeding the CY-11A specification of 472.4" (12m). This represents an enhancement in detection capability.

Engineering Selection Recommendations

The NX5-M30A is an active product with current manufacturing status, whereas the CY-11A is obsolete. Selection of the NX5-M30A ensures access to ongoing supply, technical support, and compliance with current regulatory standards (ROHS3). Both sensors are manufactured by the same supplier, ensuring consistency in design philosophy and quality standards.

The NX5-M30A meets or exceeds all critical electrical and functional parameters of the CY-11A. The improved response time (10ms versus 20ms) and extended sensing distance (30m versus 12m) provide performance advantages. The IP66 rating remains suitable for industrial environments where the CY-11A IP67 was specified, with the understanding that IP66 provides protection against powerful water jets while IP67 provides temporary immersion protection.

Temperature operating range overlap (-20°C to 55°C) covers the majority of industrial applications within the CY-11A specification. For applications requiring operation below -20°C, alternative solutions should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the NX5-M30A directly replace the CY-11A in existing installations?

A: Yes, the NX5-M30A is functionally compatible as a substitute. Both sensors employ through-beam detection with infrared light source, light-on output configuration, and cable connection. Electrical compatibility is confirmed through overlapping voltage supply ranges (24V ~ 240V). Physical mounting and connector compatibility should be verified against your specific installation requirements.

Q: What is the difference between IP66 and IP67 ratings?

A: IP67 provides protection against temporary immersion in water up to 1 meter for 30 minutes, while IP66 protects against powerful water jets from any direction. For most industrial sensor applications, both ratings provide equivalent protection. Applications requiring submersion capability should retain IP67-rated sensors.

Q: Does the NX5-M30A's longer sensing distance affect compatibility?

A: The extended sensing distance of 30m (versus 12m) represents a capability enhancement. In applications where the CY-11A was selected for 12m detection, the NX5-M30A will perform identically at that distance while offering additional range if needed. No compatibility issues arise from this specification difference.

Q: What is the significance of the 2m cable length on the NX5-M30A?

A: The NX5-M30A includes a 2m (78.74") integrated cable. The CY-11A cable length was not specified in available documentation. Verify that the 2m cable length accommodates your installation geometry. Cable extension options should be evaluated if longer runs are required.

Q: Are there compliance differences between the two sensors?

A: The CY-11A is RoHS Compliant, while the NX5-M30A is ROHS3 Compliant. ROHS3 represents the current regulatory standard and provides assurance of compliance with the latest environmental directives. Both sensors carry EAR99 ECCN classification and 8541.49.8000 HTSUS code.

Q: What is the response time difference, and does it matter?

A: The NX5-M30A responds in 10ms compared to the CY-11A at 20ms. This 10ms improvement means faster detection and output switching. For applications with critical timing requirements, the faster response time of the NX5-M30A provides a performance advantage. For standard industrial detection applications, both response times are typically acceptable.
