Key Parameters

Substitute Part Grouping Explanation

The PM-Y45-P is identified as a substitute for the PM-Y44P based on the following substitution criteria:

Common Parameters (Substitution Basis):

• Sensing Method: Through-Beam (both sensors use identical detection principle)
• Output Configuration: PNP - Open Collector (compatible with PNP applications)
• Mounting Type: Chassis Mount (identical mechanical interface)
• Package / Case: Module, Wire Leads (same form factor category)
• Response Time: 20µs (identical response characteristic available)
• RoHS Status: Compliant (both meet environmental standards)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical reliability rating)
• ECCN and HTSUS Classification: Identical regulatory codes

Allowable Variation:

• Sensing Distance: PM-Y45-P operates at 0.236" (6mm) versus PM-Y44P at 0.197" (5mm). This represents a 0.039" (1mm) increase in sensing range, which is acceptable for through-beam slot-type sensors where the slot geometry can accommodate the extended detection distance.
• Voltage - Supply: PM-Y45-P operates at 5V ~ 24V, providing broader supply voltage compatibility than the PM-Y44P specification.
• Current - Supply: PM-Y45-P specifies 15 mA supply current, aligning with the PM-Y44P collector current maximum.

Parameter Comparison

Engineering Selection Recommendations

The PM-Y45-P is the designated substitute for the obsolete PM-Y44P based on functional equivalence and regulatory compliance. The PM-Y45-P is currently in active production status, ensuring availability for replacement and new applications.

Both sensors meet RoHS compliance requirements. The PM-Y45-P achieves ROHS3 compliance, representing current environmental standards. Both components maintain identical moisture sensitivity ratings (MSL 1 - Unlimited), confirming equivalent reliability characteristics for industrial deployment.

The primary technical difference is the sensing distance increase from 0.197" (5mm) to 0.236" (6mm). This variation is within acceptable parameters for through-beam slot-type optical sensors, as the slot geometry typically accommodates this range without functional degradation. The PM-Y45-P's broader supply voltage range (5V ~ 24V) provides enhanced flexibility compared to the PM-Y44P specification.

Selection of the PM-Y45-P is appropriate for direct replacement applications where the PM-Y44P is specified, provided the mechanical slot dimensions and electrical supply parameters are compatible with the system design.

Frequently Asked Questions (FAQ)

Q: Can the PM-Y45-P directly replace the PM-Y44P in existing installations?

A: Yes, the PM-Y45-P is functionally equivalent for through-beam slot-type optical sensing applications. Both sensors use identical sensing methodology, output configuration (PNP), mounting type (Chassis Mount), and response time (20µs). The 0.039" (1mm) increase in sensing distance is accommodated by standard slot geometries used in industrial automation equipment.

Q: What is the significance of the sensing distance difference between these sensors?

A: The PM-Y44P operates at 0.197" (5mm) sensing distance, while the PM-Y45-P operates at 0.236" (6mm). This represents a 1mm increase in detection range. For through-beam slot-type sensors, this variation falls within the tolerance of typical slot dimensions and does not compromise functional performance.

Q: Are there output configuration differences between these sensors?

A: The PM-Y44P features selectable dark-ON/light-ON output configuration, while the PM-Y45-P uses PNP open collector output. Both are PNP-based configurations suitable for industrial control circuits. The PM-Y45-P's open collector output is a standard industrial interface compatible with typical automation control systems.

Q: What is the product status difference, and why does it matter?

A: The PM-Y44P is classified as obsolete, indicating discontinued production. The PM-Y45-P is in active production status, ensuring ongoing availability for procurement, replacement, and new system designs. This status difference makes the PM-Y45-P the recommended choice for current applications.

Q: Are the RoHS compliance ratings equivalent?

A: Both sensors meet RoHS compliance standards. The PM-Y44P is RoHS Compliant, while the PM-Y45-P achieves ROHS3 Compliant status, representing current environmental regulatory requirements. Both components are suitable for applications requiring RoHS-compliant components.

Q: What are the supply voltage specifications for each sensor?

A: The PM-Y44P specifies a maximum collector-emitter breakdown voltage of 30V. The PM-Y45-P operates at a supply voltage range of 5V ~ 24V. The PM-Y45-P's defined supply voltage range provides clearer operational parameters for system design and integration.
