PM-R64 Equivalent & Substitute Parts
Part Overview
The PM-R64 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.

Substitute Part Grouping Explanation
Substitute parts for the PM-R64 are identified based on the following critical parameters that determine functional compatibility:
Parametric Equivalents maintain identical electrical and mechanical specifications across all key parameters: sensing distance (0.197" / 5mm), sensing method (through-beam), output configuration (NPN with selectable Dark-ON/Light-ON), response time (20µs), operating temperature range (-25°C ~ 55°C), and mounting type (chassis mount). These parts are direct functional replacements.
Similar Substitutes share the same sensing method (through-beam), mounting type (chassis mount), and response time (20µs), but differ in sensing distance, output configuration, or supply voltage specifications. These parts require circuit evaluation before implementation.

Engineering Selection Recommendations
PM-L64 (Parametric Equivalent): This part maintains identical electrical and mechanical specifications to the PM-R64, including sensing distance, output configuration with selectable Dark-ON/Light-ON, response time, and operating temperature range. Both parts are obsolete and RoHS compliant. Selection of PM-L64 requires no circuit modifications and provides direct functional replacement.
PM-R65 (Similar Substitute): This part is currently active and ROHS3 compliant, offering extended product lifecycle support. However, PM-R65 differs in three critical parameters: sensing distance (0.236" / 6mm versus 0.197" / 5mm), output configuration (NPN Open Collector versus selectable Dark-ON/Light-ON), and supply voltage specification (5V ~ 24V). Implementation of PM-R65 requires evaluation of mechanical spacing constraints and output signal compatibility with existing control circuitry.
Frequently Asked Questions (FAQ)
Q: Can PM-R65 directly replace PM-R64 in existing applications?
A: PM-R65 shares the same sensing method, response time, and operating temperature range as PM-R64. However, the increased sensing distance (6mm versus 5mm) and different output configuration (open collector versus selectable Dark-ON/Light-ON) require mechanical and electrical circuit evaluation before implementation.
Q: What is the difference between PM-L64 and PM-R64?
A: PM-L64 and PM-R64 are parametric equivalents with identical electrical and mechanical specifications. Both feature 0.197" (5mm) sensing distance, NPN output with selectable Dark-ON/Light-ON configuration, 20µs response time, and -25°C to 55°C operating temperature. Both are obsolete products.
Q: Are all substitute parts RoHS compliant?
A: Yes. PM-R64 is RoHS Compliant, PM-L64 is RoHS Compliant, and PM-R65 is ROHS3 Compliant. All parts meet RoHS environmental standards.
Q: What are the key parameters that determine substitution compatibility?
A: Substitution compatibility is determined by sensing distance, sensing method, output configuration, response time, operating temperature range, and mounting type. Deviations in any of these parameters require circuit and mechanical evaluation.
Q: Why is PM-R64 marked as obsolete?
A: PM-R64 is classified as obsolete by the manufacturer. PM-R65 is the active product offering from Panasonic Industrial Automation Sales for similar through-beam optical sensing applications.
