PM-K54P Equivalent & Substitute Parts

Part Overview

The PM-K54P 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 automation applications. The PM-K54P is currently listed as obsolete, making identification of compatible substitute components essential for system maintenance and new design implementations. The 5mm sensing distance and 20µs response time define its operational envelope for slot detection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM-K54P 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 detection applications.

Output Configuration: The PNP output type must be preserved. The PM-K54P features selectable dark-ON/light-ON functionality; substitute parts must support PNP open collector output compatible with the same control logic.

Mounting Type: Chassis mount configuration must be maintained for mechanical compatibility with existing installations.

Package Type: Module format with wire leads is required for direct replacement in legacy systems.

Response Time: The 20µs response time establishes the maximum acceptable switching speed. Substitute parts meeting or exceeding this specification maintain temporal performance requirements.

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

Electrical Ratings: Collector current (Ic) and voltage ratings must meet or exceed the PM-K54P specifications to ensure safe operation within existing circuit designs.

The PM-K45-P qualifies as a substitute based on these parameters, despite a different sensing distance (6mm vs. 5mm), because the through-beam method, PNP output, chassis mount configuration, module package, response time, temperature range, and electrical compatibility remain consistent with the PM-K54P operational requirements.

Parameter Comparison

Engineering Selection Recommendations

The PM-K45-P is an active product with current manufacturing status, whereas the PM-K54P is obsolete. For new designs or system replacements, the PM-K45-P provides continuity of supply and ongoing manufacturer support. Both components maintain RoHS compliance and identical export classification (EAR99), ensuring regulatory consistency.

The primary design consideration is the sensing distance differential: the PM-K45-P operates at 6mm versus the PM-K54P at 5mm. This 1mm increase in sensing distance may require mechanical adjustment in slot-type applications to maintain proper object detection. The response time specification of 20µs is available on the PM-K45-P, matching the PM-K54P performance envelope.

Both components share identical operating temperature ranges (-25°C ~ 55°C) and moisture sensitivity levels (MSL 1), confirming environmental compatibility. The PNP output configuration is preserved across both parts, maintaining control circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can the PM-K45-P directly replace the PM-K54P in existing installations?

A: Mechanical compatibility depends on the slot width and object detection geometry. The PM-K45-P sensing distance of 6mm versus the PM-K54P at 5mm represents a 1mm difference. If the original application requires the 5mm sensing distance for proper slot detection, mechanical repositioning or application redesign may be necessary. Both parts share identical through-beam sensing method, PNP output, and response time characteristics.

Q: What is the significance of the selectable dark-ON/light-ON feature on the PM-K54P?

A: The PM-K54P offers selectable output logic, allowing configuration for either dark-ON (output active when slot is blocked) or light-ON (output active when slot is clear) operation. The PM-K45-P specifies PNP open collector output without explicit mention of selectable logic. Verify the control circuit requirements before substitution to ensure output logic compatibility.

Q: Are there supply voltage differences between these components?

A: The PM-K45-P specifies a supply voltage range of 5V ~ 24V. The PM-K54P does not provide supply voltage specifications in the available data. Confirm the power supply voltage of the existing system to ensure the PM-K45-P operates within its specified range.

Q: What is the inventory status for these components?

A: The PM-K54P has 943 pieces in stock as new original inventory. The PM-K45-P has 2600 pieces in stock. Given the obsolete status of the PM-K54P, the PM-K45-P represents a more sustainable long-term supply option.

Q: Do both components meet the same regulatory standards?

A: Both the PM-K54P and PM-K45-P are classified as EAR99 for export control and share the same HTSUS code (8543.70.9860). The PM-K54P is RoHS Compliant, while the PM-K45-P is ROHS3 Compliant, representing an updated compliance standard. Both components have MSL 1 (Unlimited) moisture sensitivity ratings.
