PM-T54P Equivalent & Substitute Parts

Part Overview

The PM-T54P is an optical sensor manufactured by Panasonic Industrial Automation Sales, designed as a through-beam slot-type module with selectable dark-ON/light-ON output configuration. This component operates with PNP output and is classified as an unamplified optical sensor for industrial automation applications. The PM-T54P is currently listed as obsolete, making identification of compatible substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the PM-T54P are determined by the following critical parameters:

• Sensing Method: Through-beam optical detection
• Output Configuration: PNP transistor output
• Mounting Type: Chassis mount with wire leads
• Package Type: Slot-type module form factor
• Response Time: 20µs performance specification
• Operating Temperature Range: -25°C ~ 55°C
• Regulatory Compliance: RoHS and ECCN classification

The PM-T45-P qualifies as a substitute based on matching sensing method (through-beam), output type (PNP), mounting configuration (chassis mount), package style (module with wire leads), response time capability (20µs available), operating temperature range (-25°C ~ 55°C), and regulatory compliance (RoHS3, EAR99). The primary difference is the sensing distance specification: PM-T45-P operates at 0.236" (6mm) compared to the PM-T54P at 0.197" (5mm).

Parameter Comparison

Engineering Selection Recommendations

The PM-T45-P is an active product with current manufacturing status, whereas the PM-T54P is obsolete. Both components maintain identical regulatory compliance classifications (EAR99, HTSUS 8543.70.9860) and equivalent moisture sensitivity levels (MSL 1). The PM-T45-P carries ROHS3 compliance, representing a more current environmental standard than the RoHS compliance of the PM-T54P.

The primary technical distinction is the sensing distance: the PM-T45-P operates at 0.236" (6mm) versus the PM-T54P at 0.197" (5mm). This 1mm difference in sensing distance must be evaluated against specific application slot width requirements. Both components share identical response time capability at 20µs and matching operating temperature ranges (-25°C ~ 55°C).

The PM-T45-P output configuration is specified as PNP - Open Collector, whereas the PM-T54P offers selectable dark-ON/light-ON functionality. Application logic requirements must be assessed to determine if the fixed open collector output of the PM-T45-P is compatible with existing system design.

Frequently Asked Questions (FAQ)

Q: Can the PM-T45-P directly replace the PM-T54P in existing installations?

A: Direct replacement requires verification of three factors: (1) slot width compatibility with the 6mm sensing distance of the PM-T45-P versus the 5mm specification of the PM-T54P, (2) compatibility of the fixed PNP open collector output with system logic requirements, and (3) confirmation that the 5V ~ 24V supply voltage range of the PM-T45-P matches the system power architecture.

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

A: The sensing distance defines the maximum gap width between the emitter and receiver in a through-beam configuration. The PM-T54P operates at 0.197" (5mm) while the PM-T45-P operates at 0.236" (6mm). This difference affects the physical slot width that can be accommodated. Applications with slot widths exceeding 5mm require the PM-T45-P; applications with narrower slots may not function with the PM-T45-P.

Q: Are there differences in output behavior between these sensors?

A: The PM-T54P provides selectable dark-ON/light-ON output configuration, allowing field selection of the logic state. The PM-T45-P specifies PNP open collector output without mention of selectable logic states. System design must accommodate this fixed output behavior.

Q: Do both parts meet current environmental compliance standards?

A: Both components are classified under identical ECCN (EAR99) and HTSUS (8543.70.9860) codes. The PM-T45-P carries ROHS3 compliance, representing current environmental standards, while the PM-T54P carries RoHS compliance. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the inventory status for these components?

A: The PM-T54P is listed as obsolete with 1060 pieces in stock. The PM-T45-P is an active product with 1447 pieces in stock, providing ongoing availability for new procurement.
