CY-29 Equivalent & Substitute Parts

Part Overview

The CY-29 is a retroreflective optical sensor manufactured by Panasonic Industrial Automation Sales, designed for 5.9" (15cm) sensing distance applications with NPN open collector output. This sensor operates across a 10V to 30V supply range and features a red LED light source with IP67 ingress protection. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and new design implementations where retroreflective sensing functionality is required.

Key Parameters

Substitute Part Grouping Explanation

The E3FA-RN11 2M from Omron Automation and Safety qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Voltage supply range: Both operate at 10V ~ 30V
• Output configuration: Both feature NPN output with open collector capability
• Light source: Both utilize red LED technology
• Connection method: Both use cable connections
• Ingress protection: Both meet or exceed IP67 rating
• Cable length: Both provide 78.74" (2m) cable
• Operating temperature range: Both function across -25°C ~ 55°C
• RoHS compliance: Both are RoHS compliant

Key Difference: The E3FA-RN11 2M employs reflective sensing methodology with a selectable dark-ON/light-ON output configuration and supports an extended sensing distance range of 3.937" ~ 157.48" (100mm ~ 4m), compared to the CY-29's fixed 5.9" (15cm) retroreflective distance. The E3FA-RN11 2M response time of 500µs is faster than the CY-29's 2ms specification.

Parameter Comparison

Engineering Selection Recommendations

The E3FA-RN11 2M is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for applications previously served by the obsolete CY-29. Both sensors maintain identical supply voltage specifications and operating temperature ranges, ensuring compatibility with existing power distribution and environmental requirements.

The E3FA-RN11 2M's selectable dark-ON/light-ON output configuration provides operational flexibility not present in the CY-29's fixed open collector output. The extended sensing distance capability of the E3FA-RN11 2M accommodates applications requiring variable detection ranges within the 100mm to 4m spectrum, while maintaining performance at the CY-29's original 15cm specification.

The E3FA-RN11 2M achieves IP69K ingress protection, exceeding the CY-29's IP67 rating, providing enhanced environmental sealing for applications in high-pressure wash or contaminated environments.

Frequently Asked Questions (FAQ)

Q: Can the E3FA-RN11 2M directly replace the CY-29 in existing installations?

A: The E3FA-RN11 2M is electrically compatible with the CY-29 across supply voltage (10V ~ 30V), output type (NPN open collector), and operating temperature range (-25°C ~ 55°C). Physical mounting and connector compatibility must be verified against the specific installation requirements.

Q: What is the primary functional difference between these sensors?

A: The CY-29 uses retroreflective sensing, requiring a reflector positioned at the target distance. The E3FA-RN11 2M uses reflective sensing, detecting objects directly without requiring a separate reflector. Both achieve detection at 15cm, but the E3FA-RN11 2M supports variable distances from 100mm to 4m.

Q: Does the E3FA-RN11 2M's faster response time (500µs vs. 2ms) affect compatibility?

A: The faster response time of the E3FA-RN11 2M is a performance enhancement that does not create compatibility issues. Applications designed for the CY-29's 2ms response will function correctly with the E3FA-RN11 2M's 500µs response.

Q: Are both sensors RoHS compliant?

A: Yes. The CY-29 is RoHS Compliant, and the E3FA-RN11 2M is ROHS3 Compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What packaging is provided with the E3FA-RN11 2M?

A: The E3FA-RN11 2M is supplied in Box packaging, suitable for standard component storage and distribution.
