CY-17B Retroreflective Optical Sensor - Equivalent & Substitute Parts

Part Overview

The CY-17B is a retroreflective optical sensor manufactured by Panasonic Industrial Automation Sales, designed for detection applications requiring a fixed sensing distance of 118.1" (3m). This sensor operates on 24~240 VAC supply voltage with dark-on output configuration and infrared light source. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CY-17B is determined by the following critical parameters:

Primary Substitution Criteria:

• Sensing method must be retroreflective
• Sensing distance capability must encompass or exceed 118.1" (3m)
• Output configuration must support dark-on operation
• Ingress protection rating must meet or exceed IP67
• Operating temperature range must encompass -25°C ~ 55°C
• Connection method must be cable-based
• RoHS compliance status must be maintained

Secondary Compatibility Factors:

• Supply voltage compatibility with existing system infrastructure
• Response time performance relative to application requirements
• Light source type (infrared or red LED acceptable for retroreflective sensing)

The E3RB-RN11 2M qualifies as a substitute based on retroreflective sensing capability, adjustable sensing distance range (3.937" ~ 118.11"), selectable dark-on output configuration, IP67/IP69K ingress protection, matching operating temperature range, cable connection, and RoHS compliance. However, supply voltage differs significantly, requiring circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The E3RB-RN11 2M from Omron Automation and Safety is functionally equivalent to the obsolete CY-17B for retroreflective sensing applications within the 3-meter distance range. Both components maintain RoHS compliance and operate across the identical temperature envelope.

Critical Consideration: The E3RB-RN11 2M operates on 10V~30V DC supply, whereas the CY-17B requires 24~240 VAC. This voltage incompatibility necessitates power supply circuit redesign or selection of an alternative substitute if AC operation is mandatory in the existing system architecture.

The E3RB-RN11 2M offers superior response time (500µs versus 20ms) and enhanced ingress protection (IP69K capability), providing performance advantages for applications requiring faster detection cycles or operation in high-pressure wash environments.

Frequently Asked Questions (FAQ)

Q: Can the E3RB-RN11 2M directly replace the CY-17B in an existing 24 VAC system?

A: No. The E3RB-RN11 2M requires 10V~30V DC power supply. Direct substitution requires power supply circuit modification or selection of an alternative AC-compatible retroreflective sensor.

Q: What does "selectable" output configuration mean for the E3RB-RN11 2M?

A: The E3RB-RN11 2M supports both dark-on and light-on output modes through user selection, providing operational flexibility. The CY-17B is fixed at dark-on configuration.

Q: Are the sensing distances truly equivalent?

A: The E3RB-RN11 2M provides an adjustable sensing range of 3.937" to 118.11" (100mm to 3m), which encompasses the CY-17B fixed distance of 118.1" (3m). The E3RB-RN11 2M can be adjusted to match the CY-17B operating distance through single-turn adjustment.

Q: Does the difference in light source (infrared vs. red LED) affect retroreflective sensing performance?

A: Both infrared and red LED light sources are suitable for retroreflective sensing applications. The choice between them depends on specific environmental conditions and reflector material compatibility, which are not specified in the provided parameters.

Q: What is the significance of IP69K rating on the E3RB-RN11 2M compared to IP67 on the CY-17B?

A: IP69K provides enhanced protection against high-pressure water jets and steam cleaning, exceeding the IP67 dust and water immersion protection of the CY-17B. This makes the E3RB-RN11 2M suitable for more demanding environmental conditions.

Q: Are both components RoHS compliant?

A: Yes. Both the CY-17B and E3RB-RN11 2M are RoHS compliant, ensuring regulatory compliance for applications subject to RoHS requirements.
