Key Parameters

Substitute Part Grouping Explanation

The PM-R45-P is identified as a substitute for the PM-R44P based on the following critical parameters that determine functional compatibility:

Shared Core Characteristics:

• Sensing Method: Through-Beam optical detection
• Output Configuration: PNP output topology
• Mounting Type: Chassis Mount
• Package Type: Module with Wire Leads
• Response Time: 20µs (matching primary specification)
• Operating Temperature Range: -25°C ~ 55°C
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8543.70.9860

Allowable Parameter Variance:

• Sensing Distance: PM-R44P operates at 0.197" (5mm), while PM-R45-P operates at 0.236" (6mm). This represents a 1mm increase in sensing distance, which is within acceptable tolerance for slot-type through-beam applications where the gap width can accommodate this variation.
• Output Configuration Detail: PM-R44P features selectable Dark-ON/Light-ON functionality, while PM-R45-P provides PNP Open Collector output. Both configurations are PNP-based and suitable for industrial control circuits.
• Supply Voltage: PM-R45-P specifies 5V ~ 24V supply range, providing broader voltage compatibility than the PM-R44P specification.

Parameter Comparison

Engineering Selection Recommendations

The PM-R45-P is an active product with current manufacturing status, whereas the PM-R44P is obsolete. Both components maintain identical RoHS compliance frameworks (RoHS Compliant and ROHS3 Compliant respectively) and share the same export classification (EAR99) and tariff code (8543.70.9860).

The PM-R45-P is the designated substitute for new designs and replacement applications. The 1mm increase in sensing distance (from 5mm to 6mm) is accommodated within standard slot-type sensor mounting tolerances. Both sensors maintain identical response time specifications at 20µs and operate across the same temperature range.

The PM-R45-P provides broader supply voltage flexibility (5V ~ 24V) compared to the PM-R44P, enhancing system integration flexibility. Both components are unamplified through-beam optical sensors with PNP output topology, ensuring functional compatibility in existing control circuits.

Frequently Asked Questions (FAQ)

Q: Can PM-R45-P directly replace PM-R44P in existing assemblies?

A: The PM-R45-P is functionally compatible as a substitute. Both sensors share identical sensing method (through-beam), output topology (PNP), response time (20µs), operating temperature range (-25°C ~ 55°C), and mounting configuration (chassis mount). The sensing distance difference of 1mm (5mm vs. 6mm) is within acceptable tolerance for slot-type applications where the gap width can accommodate this variation.

Q: What is the significance of the sensing distance difference?

A: The PM-R44P operates at 0.197" (5mm) sensing distance, while the PM-R45-P operates at 0.236" (6mm). This 1mm difference represents the maximum detection range for each sensor. In slot-type through-beam configurations, the physical gap width determines which sensor is appropriate. If the existing slot width is 5mm or less, the PM-R44P specification is required. If the slot width is 6mm or greater, the PM-R45-P is suitable.

Q: Are there output configuration differences between these sensors?

A: The PM-R44P features selectable Dark-ON/Light-ON output, while the PM-R45-P provides PNP Open Collector output. Both are PNP-based configurations suitable for industrial control circuits. The PM-R45-P output topology is standard for through-beam optical sensors and is compatible with typical industrial control inputs.

Q: What is the product status significance?

A: The PM-R44P is classified as obsolete, indicating discontinued manufacturing. The PM-R45-P is an active product with current production. For new designs, maintenance applications, and long-term system support, the PM-R45-P is the appropriate selection.

Q: Are compliance certifications equivalent?

A: Both sensors maintain RoHS compliance (PM-R44P: RoHS Compliant; PM-R45-P: ROHS3 Compliant), share identical ECCN classification (EAR99), and identical HTSUS tariff code (8543.70.9860). Both components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What supply voltage specifications apply?

A: The PM-R45-P specifies a supply voltage range of 5V ~ 24V, providing broader compatibility than the PM-R44P. This expanded range enhances integration flexibility in systems with varying power supply configurations.
