PM-Y64 Equivalent & Substitute Parts

Part Overview

The PM-Y64 is an optical sensor module manufactured by Panasonic Industrial Automation Sales, designed for through-beam sensing applications with a 0.197" (5mm) sensing distance. The sensor features NPN output with selectable Dark-ON/Light-ON configuration, operating across -25°C to 55°C. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, redesign, and procurement planning.

Engineering Selection Recommendations

PM-L64 (Parametric Equivalent): This part maintains identical electrical and mechanical specifications to the PM-Y64, including sensing distance, output configuration with selectable Dark-ON/Light-ON modes, response time, and package type. Both parts are obsolete and RoHS compliant. Selection of PM-L64 is appropriate when direct functional replacement is required without design modification.

PM-Y65 (Similar Substitute): This part is currently active and ROHS3 compliant, offering improved product availability compared to the obsolete PM-Y64. The PM-Y65 differs in sensing distance (0.236" vs. 0.197") and output configuration (fixed NPN Open Collector vs. selectable Dark-ON/Light-ON). The PM-Y65 is suitable for applications where the increased sensing distance is acceptable and the fixed output configuration meets system requirements. Supply voltage specification (5V ~ 24V) and current supply (15 mA) are provided for this part.

Frequently Asked Questions (FAQ)

Q: Can PM-L64 be used as a direct replacement for PM-Y64? A: Yes. PM-L64 maintains identical sensing distance (0.197" / 5mm), output configuration (NPN - Dark-ON/Light-ON - Selectable), response time (20µs), operating temperature range (-25°C ~ 55°C), and package type (Module, Connector, Slot Type). Both parts are obsolete and RoHS compliant.

Q: What is the primary difference between PM-Y65 and PM-Y64? A: The PM-Y65 has a sensing distance of 0.236" (6mm) compared to PM-Y64's 0.197" (5mm). Additionally, PM-Y65 features fixed NPN Open Collector output, whereas PM-Y64 offers selectable Dark-ON/Light-ON configuration. PM-Y65 is currently active, improving availability.

Q: Can PM-Y65 replace PM-Y64 in existing designs? A: PM-Y65 can replace PM-Y64 only if the application tolerates the increased sensing distance (6mm vs. 5mm) and the fixed NPN Open Collector output configuration. Circuit design modifications may be required if the selectable Dark-ON/Light-ON feature is critical to system operation.

Q: Are all three parts RoHS compliant? A: PM-Y64 and PM-L64 are RoHS Compliant. PM-Y65 is ROHS3 Compliant. All three parts meet RoHS requirements.

Q: What is the response time for these optical sensors? A: All three parts (PM-Y64, PM-Y65, and PM-L64) have a response time of 20µs.

Q: What are the operating temperature ranges? A: PM-Y64 and PM-L64 operate across -25°C ~ 55°C. PM-Y65 operates across -25°C ~ 55°C (TA).
