PM-K24P Equivalent & Substitute Parts

Part Overview

The PM-K24P is an optical sensor manufactured by Panasonic Industrial Automation Sales, designed as a through-beam slot-type sensor with PNP output configuration and selectable Dark-ON/Light-ON functionality. This component operates at a 0.197" (5mm) sensing distance and is classified as an unamplified module with wire leads for chassis mounting applications.

The PM-K24P is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure design continuity, and support ongoing production or maintenance requirements where original components are no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-K24P is determined by the following critical parameters:

• Sensing Method: Through-beam optical sensing capability
• Output Configuration: PNP output type with open collector topology
• Sensing Distance: Optical detection range (0.197" / 5mm for PM-K24P)
• Response Time: Signal switching speed (20µs)
• Operating Temperature Range: -25°C ~ 55°C
• Mounting Type: Chassis mount with wire leads
• Electrical Ratings: Collector current (15 mA max), voltage breakdown (30 V max)
• Compliance: RoHS compliance status

The PM-K25-P qualifies as a substitute based on matching through-beam sensing method, PNP output configuration, identical response time, overlapping operating temperature range, and equivalent mounting and packaging approach. The primary difference is the increased sensing distance (0.236" / 6mm) and active product status, which provides improved availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The PM-K25-P serves as the primary substitute for the obsolete PM-K24P. Both components share identical response time (20µs), operating temperature range (-25°C ~ 55°C), and through-beam sensing methodology with PNP output configuration. The PM-K25-P maintains RoHS compliance with ROHS3 certification, exceeding the RoHS Compliant status of the original part.

The PM-K25-P is currently in active production status with 1370 units in stock, ensuring supply chain continuity and long-term availability. The increased sensing distance (0.236" / 6mm versus 0.197" / 5mm) represents the primary design difference and must be evaluated against specific application requirements.

Selection of the PM-K25-P is supported by equivalent electrical performance, matching response characteristics, and superior product lifecycle status. Mechanical integration should be verified to confirm compatibility with existing slot-type mounting configurations.

Frequently Asked Questions (FAQ)

Q: What is the primary reason the PM-K24P requires substitution?

A: The PM-K24P is classified as obsolete. The PM-K25-P is an active product that provides equivalent optical sensing functionality with improved availability and manufacturer support.

Q: Are the sensing distances interchangeable between PM-K24P and PM-K25-P?

A: No. The PM-K24P operates at 0.197" (5mm) sensing distance, while the PM-K25-P operates at 0.236" (6mm). Applications requiring precise sensing distance must evaluate whether the increased range of the PM-K25-P is compatible with the target application geometry.

Q: Do both parts share the same response time?

A: Yes. Both the PM-K24P and PM-K25-P operate at 20µs response time, ensuring equivalent signal switching performance in time-critical applications.

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

A: The PM-K24P provides selectable Dark-ON/Light-ON functionality within a PNP configuration. The PM-K25-P provides PNP open collector output. Both are PNP topology; the PM-K24P offers additional output mode flexibility.

Q: Are both parts RoHS compliant?

A: Yes. The PM-K24P is RoHS Compliant. The PM-K25-P is ROHS3 Compliant, representing a more current compliance standard.

Q: What is the operating temperature range for both sensors?

A: Both the PM-K24P and PM-K25-P operate across -25°C ~ 55°C, providing identical thermal performance specifications.

Q: Can the PM-K25-P be used in existing PM-K24P mounting locations?

A: Mechanical compatibility must be verified. Both components are chassis-mount modules with wire leads; however, the PM-K24P is specified as slot-type while the PM-K25-P is specified as module type. Physical dimensions and mounting interface should be confirmed before integration.

Q: What supply voltage does the PM-K25-P require?

A: The PM-K25-P operates across 5V ~ 24V supply voltage range with 15 mA supply current. Verify that existing power supply infrastructure supports this voltage range.
