Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-L24-C3 is determined by the following critical parameters:

Sensing Method: Through-beam operation is the primary functional requirement. Substitute parts must maintain this detection principle.

Output Configuration: NPN output with open collector topology is essential for circuit compatibility. The PM-L24-C3 features selectable dark-on/light-on operation; substitute parts must support NPN output.

Sensing Distance: The 0.197" (5mm) sensing distance defines the optical path and detection range. Substitute parts with different sensing distances may require mechanical or optical redesign.

Response Time: The 20µs response time establishes the detection speed requirement. Substitute parts must meet or exceed this specification.

Operating Temperature Range: The -25°C ~ 55°C operating range defines environmental compatibility. Substitute parts must support this temperature envelope.

Mounting Type and Package: Chassis mount with module and wire leads configuration ensures mechanical compatibility with existing installations.

Electrical Ratings: Maximum collector current (15 mA), forward current (50 mA), and collector-emitter breakdown voltage (30 V) establish circuit load compatibility.

The PM-L25-C3 qualifies as a substitute based on maintained through-beam sensing method, NPN output configuration, identical response time, matching operating temperature range, and compatible mounting and packaging specifications.

Parameter Comparison

Engineering Selection Recommendations

The PM-L25-C3 is the designated substitute for the obsolete PM-L24-C3. Both components are manufactured by Panasonic Industrial Automation Sales and maintain core through-beam optical sensing functionality with NPN output configuration.

The PM-L25-C3 is currently in active production status, ensuring availability for new installations and replacement applications. Both parts comply with RoHS requirements and possess identical moisture sensitivity ratings, supporting equivalent environmental performance.

The primary difference between these components is the sensing distance: the PM-L24-C3 operates at 0.197" (5mm) while the PM-L25-C3 operates at 0.236" (6mm). This difference may require mechanical adjustment in slot width or sensor positioning within the application. Both components maintain identical response time (20µs) and operating temperature range (-25°C ~ 55°C), ensuring equivalent detection speed and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the PM-L25-C3 directly replace the PM-L24-C3 without mechanical modification?

A: The PM-L25-C3 has a larger sensing distance (0.236" / 6mm versus 0.197" / 5mm). Direct replacement may require adjustment to the slot width or sensor positioning to maintain proper object detection. Verify mechanical compatibility with your specific application before substitution.

Q: Are the electrical characteristics compatible between these two parts?

A: Both components feature NPN output configuration with 20µs response time and operate across the identical temperature range (-25°C ~ 55°C). The PM-L25-C3 specifies supply voltage (5V ~ 24V) and supply current (15 mA), while the PM-L24-C3 specifies maximum collector current (15 mA) and collector-emitter breakdown voltage (30 V). Verify your circuit design accommodates both specifications.

Q: What is the difference in output configuration between these parts?

A: The PM-L24-C3 features selectable dark-on/light-on operation, allowing configuration of the detection logic. The PM-L25-C3 specifies NPN open collector output. Confirm your application logic requirements are compatible with the PM-L25-C3 output characteristics.

Q: Why is the PM-L24-C3 listed as obsolete?

A: The PM-L24-C3 is no longer in active production. The PM-L25-C3 represents the current equivalent offering from Panasonic Industrial Automation Sales for through-beam optical sensing applications in this product family.

Q: Are both parts RoHS compliant?

A: Yes. The PM-L24-C3 is RoHS Compliant, and the PM-L25-C3 is ROHS3 Compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing.
