PM-K64P Optical Sensor Equivalent & Substitute Parts

Part Overview

The PM-K64P is an optical through-beam sensor manufactured by Panasonic Industrial Automation Sales, designed for slot-type mounting applications with selectable dark-ON/light-ON output configuration. This component operates at a 0.197" (5mm) sensing distance and delivers PNP output with a 20µs response time. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications where continued operation is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-K64P is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Sensing method: Through-beam optical detection
• Output type: PNP configuration
• Mounting interface: Chassis mount, module connector slot type
• Response time: 20µs (matching or faster acceptable)
• Operating temperature range: -25°C ~ 55°C minimum
• Regulatory compliance: RoHS and ECCN classification alignment

Allowable Variation Parameters:

• Sensing distance: Substitutes may operate at different wavelength-dependent distances while maintaining through-beam functionality
• Current specifications: Collector current and forward current may vary within system design tolerances
• Voltage ratings: Breakdown voltage specifications may differ if system operating voltage remains within rated limits
• Supply voltage: Substitutes with different supply voltage ranges are acceptable if the application power supply is compatible

The PM-K65-P qualifies as a substitute based on shared through-beam sensing method, PNP output configuration, chassis mount design, matching response time, identical operating temperature range, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The PM-K65-P serves as the primary substitute for the obsolete PM-K64P based on functional equivalence and regulatory alignment. Both components share identical response time specifications (20µs), matching operating temperature ranges (-25°C ~ 55°C), and equivalent moisture sensitivity ratings (MSL 1). Both maintain RoHS compliance and identical ECCN/HTSUS classifications, ensuring regulatory continuity in applications requiring export or compliance documentation.

The PM-K65-P maintains active product status with current manufacturing support, addressing the obsolescence constraint of the PM-K64P. The sensing distance differential (0.236" versus 0.197") reflects the next generation in the PM series and is acceptable for through-beam applications where the optical path geometry can accommodate the increased distance specification. Both components employ unamplified PNP output architecture suitable for direct integration into industrial control systems.

Selection of the PM-K65-P is appropriate for new designs, system upgrades, and replacement scenarios where the application environment and electrical interface specifications align with the documented parameters.

Frequently Asked Questions (FAQ)

Q: Can the PM-K65-P directly replace the PM-K64P in existing installations?

A: Direct mechanical and electrical replacement is possible if the application mounting interface accommodates the module connector slot type and the optical sensing distance of 0.236" (6mm) is compatible with the slot geometry. The increased sensing distance may require mechanical adjustment of component positioning within the slot assembly.

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

A: The PM-K64P operates at 0.197" (5mm) while the PM-K65-P operates at 0.236" (6mm). This difference reflects the optical wavelength and lens design of each generation. For through-beam sensors, the sensing distance is the maximum gap between emitter and receiver. Applications with tighter slot dimensions may require mechanical redesign to accommodate the PM-K65-P.

Q: Are there output configuration differences between these parts?

A: The PM-K64P features selectable dark-ON/light-ON output, while the PM-K65-P provides PNP open collector output. Both deliver PNP logic levels suitable for industrial controllers. The PM-K64P's selectable mode offers operational flexibility not present in the PM-K65-P; application logic must be verified for compatibility with fixed open collector operation.

Q: Do both parts meet current regulatory requirements?

A: Yes. The PM-K64P carries RoHS Compliant status while the PM-K65-P carries ROHS3 Compliant status. Both maintain identical ECCN (EAR99) and HTSUS (8543.70.9860) classifications, ensuring regulatory continuity for export and compliance documentation purposes.

Q: What is the inventory status of these components?

A: The PM-K64P is obsolete with 914 pieces available as new original stock. The PM-K65-P is active with 950 pieces available as new original stock in bulk packaging, ensuring long-term availability for production and replacement applications.

Q: Are the current specifications compatible between these parts?

A: The PM-K64P specifies maximum collector current (Ic) of 15 mA and maximum DC forward current (If) of 50 mA. The PM-K65-P specifies maximum supply current of 15 mA. System design must verify that load impedance and power supply specifications accommodate the PM-K65-P's current characteristics.
