PM-R44P-C3 Equivalent & Substitute Parts

Part Overview

The PM-R44P-C3 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 sensing distance of 0.197" (5mm) and is housed in a module format with wire leads for chassis mount applications.

The PM-R44P-C3 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new design implementations where this sensor specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM-R44P-C3 are identified based on strict equivalence across the following critical parameters:

• Sensing distance: 0.197" (5mm)
• Sensing method: Through-Beam
• Output configuration: PNP with selectable dark-ON/light-ON functionality
• Current specifications: DC forward current (If) maximum 50 mA; collector current (Ic) maximum 15 mA
• Operating temperature range: -25°C ~ 55°C
• Mounting type: Chassis Mount
• Package format: Module with wire leads, slot type configuration

The EE-SX950P-R 1M from Omron Automation and Safety meets all these core electrical and mechanical parameters, establishing it as a functional equivalent for the obsolete PM-R44P-C3.

Parameter Comparison

Engineering Selection Recommendations

The EE-SX950P-R 1M is the identified substitute for the obsolete PM-R44P-C3 based on matching electrical and mechanical specifications across all critical parameters. The substitute part maintains active product status with Omron Automation and Safety, ensuring ongoing availability and supply chain continuity.

Both components are RoHS compliant, with the EE-SX950P-R 1M meeting ROHS3 standards. The substitute operates within the same temperature range and maintains identical current and sensing specifications. The voltage breakdown rating of the substitute (24 V) is lower than the original (30 V); applications operating at voltages between 24 V and 30 V require design review to confirm compatibility within the substitute's electrical envelope.

The EE-SX950P-R 1M is classified as an amplified sensor type, whereas the PM-R44P-C3 is unamplified. This difference does not affect functional equivalence for through-beam slot sensor applications with the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the EE-SX950P-R 1M directly replace the PM-R44P-C3 in existing applications?

A: Yes, the EE-SX950P-R 1M meets all critical electrical and mechanical parameters for direct substitution. Physical mounting compatibility and wire lead configuration are identical. Verify that system voltage does not exceed 24 V, as the substitute has a lower collector-emitter breakdown voltage than the original.

Q: What is the difference between unamplified and amplified sensor types in this context?

A: The PM-R44P-C3 is unamplified, while the EE-SX950P-R 1M is amplified. Both deliver equivalent PNP output with selectable dark-ON/light-ON functionality at the specified current and voltage levels. The amplified design in the substitute does not alter functional compatibility for applications using the standard electrical interface.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant. The PM-R44P-C3 carries RoHS Compliant status, while the EE-SX950P-R 1M meets the more recent ROHS3 standard. The substitute also carries REACH Unaffected status. Both share the same ECCN classification (EAR99).

Q: What should be verified before implementing the EE-SX950P-R 1M as a substitute?

A: Confirm that the system operating voltage does not exceed 24 V. Verify physical mounting clearance and wire lead routing match the original installation. Confirm that the 1M cable length of the substitute is appropriate for the application.

Q: Is the sensing distance identical between these parts?

A: Yes, both the PM-R44P-C3 and EE-SX950P-R 1M operate at a sensing distance of 0.197" (5mm) with through-beam sensing method. No adjustment to optical alignment or sensor positioning is required when substituting.
