Equivalent & Substitute Parts for PM-K64

Part Overview

The PM-K64 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, repair, and redesign applications where continued availability is required.

Substitute Part Grouping Explanation

Substitute parts for the PM-K64 are identified based on strict parametric alignment within the optical sensor category. The primary substitution criteria are:

Parametric Equivalents maintain identical or functionally equivalent specifications across all critical electrical and mechanical parameters: sensing distance, sensing method, output configuration, response time, operating temperature range, mounting type, and package form factor. These parts are direct functional replacements.

Similar Manufacturer Parts share the same sensing method and manufacturer but may differ in sensing distance or output configuration specifics. These parts require application-level verification of compatibility based on the specific system requirements.

The following parameters determine substitution validity:

• Sensing distance tolerance
• Through-beam sensing method consistency
• NPN output configuration compatibility
• Response time performance
• Operating temperature range coverage
• Chassis mount compatibility
• Module connector slot type packaging

Engineering Selection Recommendations

PM-L64 (Parametric Equivalent): This part provides complete parametric equivalence to the PM-K64 across all specified electrical and mechanical parameters. Both parts maintain identical sensing distance (0.197" / 5mm), selectable Dark-ON/Light-ON output configuration, response time (20µs), operating temperature range (-25°C ~ 55°C), and package form factor (Module, Connector, Slot Type). The PM-L64 is suitable for direct replacement in applications where the PM-K64 was originally specified. Both parts carry RoHS compliance certification and identical moisture sensitivity ratings.

PM-K65 (Similar Manufacturer Part): This part shares the same manufacturer and through-beam sensing method but differs in sensing distance (0.236" / 6mm versus 0.197" / 5mm) and output configuration (NPN - Open Collector versus NPN - Dark-ON/Light-ON - Selectable). The PM-K65 is an active product with ROHS3 compliance, providing improved availability compared to the obsolete PM-K64. Selection of the PM-K65 requires confirmation that the increased sensing distance and fixed output configuration are compatible with the target application's optical path and signal processing requirements.

Frequently Asked Questions (FAQ)

Q: Can PM-L64 be used as a direct replacement for PM-K64? A: Yes. The PM-L64 maintains identical specifications across sensing distance, output configuration, response time, operating temperature, and package type. Both are through-beam NPN sensors with selectable Dark-ON/Light-ON output and 0.197" (5mm) sensing distance.

Q: What is the primary difference between PM-K64 and PM-K65? A: The PM-K65 has a larger sensing distance of 0.236" (6mm) compared to the PM-K64's 0.197" (5mm), and uses fixed NPN - Open Collector output instead of selectable Dark-ON/Light-ON configuration. The PM-K65 is an active product, whereas PM-K64 is obsolete.

Q: Can PM-K65 replace PM-K64 in existing systems? A: Substitution requires verification that the increased sensing distance (6mm versus 5mm) and fixed output configuration (Open Collector) are compatible with the system's optical path geometry and signal processing circuit. The sensing distance difference may affect detection reliability depending on the application's object positioning tolerances.

Q: Are all three parts RoHS compliant? A: Yes. PM-K64 and PM-L64 carry RoHS Compliant certification. PM-K65 carries ROHS3 Compliant certification, which represents an updated compliance standard.

Q: What is the package compatibility between these parts? A: PM-K64 and PM-L64 use identical Module, Connector, Slot Type packaging. PM-K65 uses Module, Connector packaging without the slot type specification, which may affect mechanical mounting compatibility depending on the system's connector interface design.

Q: What is the current consumption difference between these sensors? A: All three parts specify identical maximum collector current (Ic) of 15 mA. PM-K64 and PM-L64 specify maximum DC forward current (If) of 50 mA. PM-K65 specifies supply current of 15 mA with supply voltage range of 5V ~ 24V.
