PM-F24-R Equivalent & Substitute Parts

Part Overview

The PM-F24-R is an optical sensor manufactured by Panasonic Industrial Automation Sales, classified as a through-beam slot type sensor with NPN output configuration. This component features selectable Dark-ON/Light-ON operation and is designed for applications requiring precise object detection at 0.197" (5mm) sensing distance. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

The PM-F25-R is identified as a substitute for the PM-F24-R based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Sensing Method: Through-Beam (both models)
• Output Configuration: NPN - Open Collector (PM-F25-R maintains NPN architecture)
• Response Time: 20µs (identical)
• Operating Temperature Range: -25°C ~ 55°C (identical)
• Mounting Type: Chassis Mount (identical)
• Package Type: Module, Wire Leads (both use modular wire lead construction)
• RoHS Compliance: Both RoHS Compliant
• Manufacturer: Panasonic Industrial Automation Sales (same manufacturer)

Differing Parameters:

• Sensing Distance: PM-F24-R operates at 0.197" (5mm), while PM-F25-R operates at 0.236" (6mm)
• Current - Collector (Ic) (Max): PM-F24-R rated at 15 mA; PM-F25-R operates at 15 mA supply current
• Voltage - Supply: PM-F25-R specifies 5V ~ 24V supply voltage range
• Product Status: PM-F24-R is Obsolete; PM-F25-R is Active

The substitution is valid where the increased sensing distance of 6mm is acceptable within the application requirements and where the active product status of PM-F25-R provides ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The PM-F25-R serves as the active substitute for the obsolete PM-F24-R. Both components maintain identical response time specifications (20µs) and operating temperature ranges (-25°C ~ 55°C), ensuring temporal and thermal compatibility in most applications.

The primary consideration for substitution is the sensing distance differential: the PM-F25-R operates at 0.236" (6mm) compared to the PM-F24-R's 0.197" (5mm). This 1mm increase in sensing distance must be evaluated against specific application geometry and object detection requirements.

Both components are RoHS Compliant, supporting regulatory compliance requirements. The PM-F25-R's active product status ensures continued manufacturer support, availability, and supply chain reliability compared to the obsolete PM-F24-R.

The NPN output architecture is preserved in the PM-F25-R, maintaining compatibility with existing NPN-based control circuits and signal processing interfaces.

Frequently Asked Questions (FAQ)

Q: Can PM-F25-R directly replace PM-F24-R in all applications?

A: Substitution is valid where the sensing distance increase from 5mm to 6mm does not compromise application requirements. Applications with tight spatial constraints or requiring the specific 5mm detection range may require design evaluation.

Q: Are the response times equivalent between these models?

A: Yes. Both PM-F24-R and PM-F25-R specify identical 20µs response time, ensuring equivalent temporal performance in detection and switching applications.

Q: What is the significance of the product status difference?

A: PM-F24-R is obsolete, indicating discontinued manufacturing and limited future availability. PM-F25-R is active, providing ongoing manufacturer support, supply chain availability, and potential design improvements or revisions.

Q: Are both components RoHS Compliant?

A: Yes. Both PM-F24-R and PM-F25-R are RoHS Compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: How do the output configurations differ?

A: PM-F24-R features selectable Dark-ON/Light-ON operation, while PM-F25-R operates as NPN Open Collector. Both maintain NPN architecture; the PM-F24-R provides operational mode flexibility not present in PM-F25-R.

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across -25°C to 55°C, providing equivalent thermal performance specifications.

Q: What packaging considerations apply to substitution?

A: Both components use Module with Wire Leads construction and Chassis Mount configuration. PM-F24-R specifies Slot Type packaging, while PM-F25-R uses standard module packaging. Physical form factor differences may require mechanical evaluation.
