PM-R24-R Equivalent & Substitute Parts

Part Overview

The PM-R24-R is an optical sensor manufactured by Panasonic Industrial Automation Sales, designed as a through-beam slot-type module with NPN output configuration and selectable Dark-ON/Light-ON operation. This component is classified as obsolete, making identification of compatible substitute parts essential for system maintenance and new design implementations. The 5mm sensing distance and unamplified module design position this sensor for applications requiring compact optical detection in slot-based mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-R24-R is determined by alignment 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 detection architecture.

Output Configuration: The NPN output type must be preserved. The PM-R24-R features selectable Dark-ON/Light-ON operation; substitute parts must support NPN open-collector output compatible with the same control logic.

Response Time: The 20µs response time establishes the maximum acceptable switching speed. Substitute parts must meet or exceed this specification to ensure timing-critical applications function correctly.

Operating Temperature Range: The -25°C ~ 55°C operating window must be maintained or exceeded by substitute parts to guarantee performance across the intended environmental conditions.

Mounting Type and Package: Chassis mount configuration with module and wire leads packaging ensures mechanical compatibility within existing slot-type mounting structures.

Regulatory Compliance: RoHS compliance and MSL rating of 1 (Unlimited) must be preserved in substitute selections to maintain environmental and reliability standards.

The PM-R25-R qualifies as a substitute based on these criteria, with the primary design difference being an increased sensing distance of 0.236" (6mm) compared to the original 5mm specification.

Parameter Comparison

Engineering Selection Recommendations

The PM-R25-R is an active product offering from Panasonic Industrial Automation Sales, providing continuity for applications currently using the obsolete PM-R24-R. Both components maintain identical response time specifications (20µs) and operating temperature ranges (-25°C ~ 55°C), ensuring functional compatibility in timing-sensitive and temperature-variable environments.

Both parts carry RoHS compliance certification and MSL rating of 1 (Unlimited), satisfying regulatory requirements and reliability standards for industrial automation applications. The ECCN classification (EAR99) and HTSUS code (8543.70.9860) remain consistent across both parts.

The primary design variance is the sensing distance increase from 5mm to 6mm in the PM-R25-R. This parameter difference must be evaluated against specific application requirements. Systems designed with 5mm detection gaps may require mechanical adjustment to accommodate the extended sensing distance of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the PM-R25-R directly replace the PM-R24-R without any modifications?

A: Direct replacement is possible from an electrical and control logic perspective, as both parts share identical NPN output configuration, response time, and operating temperature specifications. However, the increased sensing distance (6mm versus 5mm) may require mechanical adjustment depending on the slot width and object detection positioning in your application.

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

A: The primary difference is the sensing distance. The PM-R24-R operates at 0.197" (5mm), while the PM-R25-R operates at 0.236" (6mm). Both maintain through-beam detection architecture and NPN output configuration. The PM-R25-R also specifies NPN open-collector output, whereas the PM-R24-R offers selectable Dark-ON/Light-ON operation.

Q: Are both parts RoHS compliant?

A: Yes, both the PM-R24-R and PM-R25-R are RoHS compliant with MSL rating of 1 (Unlimited), meeting environmental and reliability standards for industrial applications.

Q: What is the response time for both sensors?

A: Both the PM-R24-R and PM-R25-R have a response time of 20µs, ensuring equivalent performance in timing-critical detection applications.

Q: Is the PM-R25-R currently available?

A: Yes, the PM-R25-R is classified as an active product with 1113 pieces in stock. The PM-R24-R is obsolete, making the PM-R25-R the recommended substitute for new designs and system maintenance.

Q: Do both sensors operate across the same temperature range?

A: Yes, both parts operate across the -25°C ~ 55°C temperature range, ensuring equivalent performance in variable environmental conditions.
