PM-F24-C3 Equivalent & Substitute Parts

Part Overview

The PM-F24-C3 is an optical sensor module manufactured by Panasonic Industrial Automation Sales, designed for through-beam sensing applications with a 0.197" (5mm) sensing distance. This NPN-output sensor features selectable Dark-ON/Light-ON operation and is supplied as an unamplified module with wire leads in a slot-type chassis mount configuration. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-F24-C3 is determined by the following critical parameters that must remain compatible:

• Sensing Method: Through-beam operation is mandatory for functional equivalence
• Output Configuration: NPN output type is required for circuit compatibility
• Response Time: 20µs specification must be maintained
• Operating Temperature Range: -25°C ~ 55°C compatibility is required
• Mounting Type: Chassis mount configuration must be preserved
• Package Type: Module with wire leads format is required

The PM-F25-C3 qualifies as a substitute based on these parameters. While the sensing distance increases from 0.197" (5mm) to 0.236" (6mm), both sensors maintain identical through-beam sensing methodology, NPN output configuration, 20µs response time, and -25°C ~ 55°C operating temperature range. Both are chassis-mount modules with wire leads and maintain RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The PM-F25-C3 is the designated substitute for the obsolete PM-F24-C3. Both sensors maintain functional equivalence through identical through-beam sensing methodology, NPN output configuration, and 20µs response time across the -25°C ~ 55°C operating temperature range.

The primary design difference is the increased sensing distance of the PM-F25-C3 (0.236" / 6mm versus 0.197" / 5mm). This parameter change must be evaluated within the context of the specific application to ensure adequate sensing range for the intended use case.

The PM-F25-C3 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both components maintain RoHS compliance, with the PM-F25-C3 meeting the more recent ROHS3 standard. The PM-F25-C3 is currently in stock with 2051 units available.

Frequently Asked Questions (FAQ)

Q: Can the PM-F25-C3 directly replace the PM-F24-C3 in existing designs?

A: The PM-F25-C3 provides functional substitution based on identical sensing methodology, NPN output type, and response time. The increased sensing distance (6mm versus 5mm) must be verified as compatible with the mechanical and optical geometry of the application.

Q: What is the primary difference between these two sensors?

A: The sensing distance differs: PM-F24-C3 operates at 0.197" (5mm) while PM-F25-C3 operates at 0.236" (6mm). Both maintain through-beam sensing, NPN output, and 20µs response time.

Q: Are there differences in output configuration between these parts?

A: The PM-F24-C3 features selectable Dark-ON/Light-ON operation, while the PM-F25-C3 provides NPN open collector output. Both are NPN-type outputs suitable for standard industrial control circuits.

Q: Why is the PM-F24-C3 marked as obsolete?

A: The PM-F24-C3 has been discontinued by Panasonic Industrial Automation Sales. The PM-F25-C3 represents the active product line continuation within the PM series optical sensor family.

Q: Are both sensors RoHS compliant?

A: Yes. The PM-F24-C3 is RoHS Compliant, and the PM-F25-C3 meets the ROHS3 standard, which represents a more recent compliance certification.

Q: What is the package configuration for both sensors?

A: Both sensors are supplied as modules with wire leads in chassis mount configuration. The PM-F24-C3 specifies slot-type packaging, while the PM-F25-C3 is supplied in bulk packaging.
