PM-L64P Equivalent & Substitute Parts

Part Overview

The PM-L64P is an optical sensor manufactured by Panasonic Industrial Automation Sales, designed as a through-beam slot-type module with PNP output configuration and selectable Dark-ON/Light-ON functionality. This component operates at a 0.197" (5mm) sensing distance and is classified as an unamplified optical sensor suitable for chassis mount applications.

The PM-L64P is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for maintenance, repair, and new installations where this sensing distance and output configuration are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-L64P is determined by the following critical parameters:

• Sensing Method: Through-beam optical sensing
• Output Configuration: PNP output type
• Mounting Type: Chassis mount with module/connector interface
• Response Time: 20µs maximum
• Operating Temperature Range: -25°C ~ 55°C
• Package Type: Module, connector, slot-type form factor

The PM-L65-P qualifies as a substitute based on matching sensing method (through-beam), output configuration (PNP), mounting type (chassis mount), response time (20µs), operating temperature range (-25°C ~ 55°C), and package type (module, connector). The primary difference is the sensing distance: PM-L65-P operates at 0.236" (6mm) compared to the PM-L64P at 0.197" (5mm). This difference is within the tolerance range for through-beam slot-type optical sensors and does not prevent functional substitution in applications where the slightly increased sensing distance is acceptable.

Engineering Selection Recommendations

The PM-L65-P is the designated substitute for the obsolete PM-L64P. Selection of the PM-L65-P is supported by the following factors:

• Product Status: PM-L65-P is active and currently in production, ensuring long-term availability and supply chain continuity.
• Compliance: PM-L65-P meets ROHS3 compliance, exceeding the RoHS compliance of the original PM-L64P.
• Functional Equivalence: Both sensors share identical response time (20µs), operating temperature range (-25°C ~ 55°C), sensing method (through-beam), output type (PNP), and mounting configuration (chassis mount).
• Sensing Distance Variance: The 0.039" (1mm) increase in sensing distance from 0.197" (5mm) to 0.236" (6mm) is a minor mechanical difference that does not affect electrical compatibility or signal characteristics in typical through-beam slot-type applications.

Frequently Asked Questions (FAQ)

Q: Can the PM-L65-P directly replace the PM-L64P in existing installations?

A: The PM-L65-P is electrically and functionally compatible with the PM-L64P. Both sensors provide PNP output, identical response time, and matching operating temperature ranges. The primary consideration is the sensing distance increase from 5mm to 6mm. Verify that the mechanical slot width and component spacing in your application accommodate the slightly larger sensing distance before installation.

Q: What is the difference between "Dark-ON/Light-ON - Selectable" and "Open Collector" output configurations?

A: The PM-L64P offers selectable output logic, allowing configuration for either dark-ON (output active when beam is blocked) or light-ON (output active when beam is unobstructed) operation. The PM-L65-P provides PNP open collector output without selectable logic. Confirm that your application's control logic is compatible with the fixed output behavior of the PM-L65-P.

Q: Are there any supply voltage differences between these sensors?

A: The PM-L64P does not specify supply voltage in the provided data. The PM-L65-P operates on 5V ~ 24V supply. Verify that your system's power supply falls within the 5V ~ 24V range when implementing the PM-L65-P.

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

A: The sensing distance determines the maximum gap between the sensor and the object being detected. The PM-L64P operates at 0.197" (5mm), while the PM-L65-P operates at 0.236" (6mm). This 1mm difference is typical among through-beam slot-type sensors in the same product family and does not affect electrical performance. Ensure your mechanical design accommodates this distance variance.

Q: Are both sensors RoHS compliant?

A: Yes. The PM-L64P is RoHS compliant. The PM-L65-P exceeds this requirement with ROHS3 compliance, indicating enhanced environmental and material standards.
