PM-T64 Equivalent & Substitute Parts

Part Overview

The PM-T64 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM-T64 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Sensing method (Through-Beam)
• Output configuration type (NPN)
• Mounting type (Chassis Mount)
• Package form factor (Module, Connector)
• Operating temperature range (-25°C ~ 55°C)
• Response time (20µs)

Sensing Distance Tolerance: The PM-T64 operates at 0.197" (5mm). The PM-T65 operates at 0.236" (6mm), representing a 1mm increase in sensing distance. This difference is acceptable for applications where the increased detection range does not conflict with system geometry or sensing requirements.

Output Configuration: The PM-T64 features selectable Dark-ON/Light-ON output. The PM-T65 provides NPN Open Collector output without selectable polarity. This represents a functional difference requiring circuit-level evaluation.

Parametric Equivalent: The PM-L64 maintains identical electrical and mechanical specifications to the PM-T64, including sensing distance, output configuration, current ratings, and voltage breakdown characteristics, making it a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

PM-L64 (Parametric Equivalent): The PM-L64 is the direct parametric equivalent to the PM-T64, matching all electrical specifications, sensing distance, output configuration, and operating parameters. Both parts are obsolete and RoHS compliant. Selection of PM-L64 requires no circuit modification and maintains identical system performance.

PM-T65 (Similar Substitute): The PM-T65 is an active product offering improved availability compared to the obsolete PM-T64. It maintains through-beam sensing methodology, NPN output, identical response time, and operating temperature range. The PM-T65 differs in sensing distance (6mm vs. 5mm) and output configuration (Open Collector vs. selectable Dark-ON/Light-ON). The PM-T65 achieves ROHS3 compliance, representing a more current regulatory status. Selection of PM-T65 requires evaluation of sensing distance tolerance and output circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can PM-T65 directly replace PM-T64 without circuit modification?

A: The PM-T65 differs in output configuration (Open Collector vs. selectable Dark-ON/Light-ON) and sensing distance (6mm vs. 5mm). Circuit-level evaluation is required to confirm compatibility with existing signal conditioning and detection logic.

Q: What is the difference between PM-L64 and PM-T64?

A: PM-L64 and PM-T64 are parametric equivalents with identical electrical specifications, sensing distance, output configuration, and operating parameters. Both are obsolete products from Panasonic Industrial Automation Sales.

Q: Does sensing distance difference between PM-T64 (5mm) and PM-T65 (6mm) affect system performance?

A: The 1mm increase in sensing distance may affect detection range and spatial resolution. System geometry and application requirements must be evaluated to determine if this difference is acceptable.

Q: Are all substitute parts RoHS compliant?

A: PM-T64 and PM-L64 are RoHS Compliant. PM-T65 is ROHS3 Compliant. Both compliance levels are acceptable for current procurement and regulatory requirements.

Q: What is the package difference between PM-T64 and PM-T65?

A: PM-T64 uses Module, Connector, Slot Type packaging. PM-T65 uses Module, Connector packaging. Mechanical fit and mounting compatibility must be verified for the specific application.

Q: Which substitute part has the best availability?

A: PM-T65 is the only active product among the three options, providing superior long-term availability and procurement reliability.
