PM-R24P Equivalent & Substitute Parts

Part Overview

The PM-R24P is an optical sensor manufactured by Panasonic Industrial Automation Sales, designed as a through-beam slot-type module with selectable dark-ON/light-ON output configuration. This component operates with PNP output and is classified as an unamplified optical sensor for industrial applications. The PM-R24P is currently listed as obsolete, making identification of compatible substitute parts essential for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-R24P is determined by compatibility across the following critical parameters:

Sensing Method: Both the main part and substitute must operate as through-beam optical sensors to maintain functional equivalence in slot-type detection applications.

Output Configuration: The PM-R24P provides PNP output with selectable dark-ON/light-ON modes. Substitute parts must support PNP output configuration to ensure compatibility with existing control circuits.

Mounting Type: Chassis mount configuration must be preserved to maintain mechanical fit within the application assembly.

Response Time: The 20µs response time establishes the performance baseline for real-time detection requirements.

Operating Temperature Range: The -25°C ~ 55°C operating window must be maintained or exceeded by substitute components.

Electrical Ratings: Collector current (15 mA max) and voltage breakdown (30 V max) specifications define the electrical interface requirements.

Compliance Standards: RoHS compliance and MSL rating ensure regulatory and environmental compatibility.

The PM-R25-P qualifies as a substitute based on these parameters, with the primary difference being an increased sensing distance of 0.236" (6mm) compared to the 0.197" (5mm) of the PM-R24P.

Parameter Comparison

Engineering Selection Recommendations

The PM-R25-P is the designated substitute for the obsolete PM-R24P. Both components are manufactured by Panasonic Industrial Automation Sales and maintain identical response time specifications (20µs) and operating temperature ranges (-25°C ~ 55°C). Both components carry MSL rating 1 (Unlimited) and comply with RoHS standards, with the PM-R25-P meeting the more recent ROHS3 specification.

The primary technical difference is the increased sensing distance of the PM-R25-P (0.236" / 6mm versus 0.197" / 5mm). This difference must be evaluated against the specific application requirements. If the original 5mm sensing distance is critical to system operation, the increased 6mm distance of the PM-R25-P may require mechanical or optical adjustment within the assembly.

The PM-R25-P is currently in active production status with 1404 units available in inventory, ensuring long-term supply availability compared to the obsolete PM-R24P.

Frequently Asked Questions (FAQ)

Q: Can the PM-R25-P directly replace the PM-R24P without any modifications?

A: The PM-R25-P is electrically and functionally compatible as a substitute. However, the increased sensing distance (6mm versus 5mm) may require mechanical repositioning or optical adjustment depending on the application's slot width and detection requirements.

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

A: The main difference is the sensing distance. The PM-R24P operates at 0.197" (5mm), while the PM-R25-P operates at 0.236" (6mm). Both maintain identical response time (20µs), operating temperature range (-25°C ~ 55°C), and PNP output configuration.

Q: Are both parts RoHS compliant?

A: Yes. The PM-R24P is RoHS Compliant, and the PM-R25-P meets the more recent ROHS3 Compliant standard. Both components satisfy RoHS environmental requirements.

Q: What is the difference between "Dark-ON/Light-ON - Selectable" and "Open Collector" output configurations?

A: The PM-R24P provides a selectable output mode allowing configuration for either dark-ON or light-ON operation. The PM-R25-P provides PNP open collector output. Both are PNP configurations suitable for industrial control circuits, but the PM-R24P offers additional operational flexibility through its selectable mode feature.

Q: Is the PM-R25-P available in the same packaging as the PM-R24P?

A: Both components use Module, Wire Leads packaging. The PM-R24P specifies Slot Type configuration, while the PM-R25-P packaging is listed as Bulk. Mechanical compatibility should be verified based on the specific slot assembly design.

Q: What is the inventory status for these parts?

A: The PM-R24P (obsolete) has 746 units in stock. The PM-R25-P (active) has 1404 units in stock, providing greater availability for new orders and future requirements.
