GX-MK12B-P-Z Equivalent & Substitute Parts

Part Overview

The GX-MK12B-P-Z is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales. This cylindrical M12-threaded sensor operates as a PNP-NC (normally closed) 3-wire device with a sensing distance of 5.6mm and is rated for IP67 and IP69K ingress protection. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and continued operation in industrial automation applications.

Key Parameters

Substitute Part Grouping Explanation

The GX-312MLK-B-P-Z qualifies as a functional substitute for the GX-MK12B-P-Z based on the following critical parameters:

Matching Parameters:

• Sensor Type: Inductive
• Output Type: PNP-NC, 3-Wire
• Ingress Protection: IP67, IP69K
• Package / Case: Cylinder, Threaded - M12
• Termination Style: Connector
• Material - Body: Nickel-Plated Brass
• Shielding: Unshielded
• Indicator: LED
• RoHS Status: RoHS Compliant

Allowable Variations:

• Sensing Distance: 0.252" (6.4mm) vs. 0.22" (5.6mm) — represents a 0.052" increase in detection range
• Response Frequency: 1.5kHz vs. 2.5kHz — lower switching speed
• Voltage Supply: 10V ~ 30V vs. 12V ~ 24V — wider input voltage tolerance
• Operating Temperature: -40°C ~ 85°C vs. -25°C ~ 70°C — extended temperature range
• Series: GX-300 vs. GX-M — different product line within same manufacturer

These variations remain within acceptable substitution parameters for inductive proximity sensors in the M12 cylindrical form factor.

Parameter Comparison

Engineering Selection Recommendations

The GX-312MLK-B-P-Z is an active product with current manufacturing status, whereas the GX-MK12B-P-Z is obsolete. Both components maintain RoHS compliance and identical ingress protection ratings (IP67, IP69K), ensuring regulatory and environmental sealing requirements are met in either configuration.

The substitute part operates across a wider voltage range (10V ~ 30V) and extended temperature spectrum (-40°C ~ 85°C), providing enhanced operational flexibility compared to the original part. The increased sensing distance of 0.252" (6.4mm) versus 0.22" (5.6mm) represents a 2.4% increase in detection range. The response frequency reduction from 2.5kHz to 1.5kHz may impact applications requiring high-speed switching cycles.

Selection of the GX-312MLK-B-P-Z is supported by active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the GX-312MLK-B-P-Z directly replace the GX-MK12B-P-Z in existing installations?

A: Yes, both sensors share identical output type (PNP-NC, 3-Wire), M12 threaded cylindrical form factor, connector termination, and ingress protection ratings. Mechanical and electrical interfaces are compatible. The increased sensing distance and lower response frequency must be evaluated against specific application requirements.

Q: What is the significance of the 0.052" difference in sensing distance?

A: The GX-312MLK-B-P-Z detects objects at 6.4mm compared to the original 5.6mm. This extended range may affect positioning accuracy in applications with tight spatial constraints. Verify that the increased detection distance does not cause false triggers or interference with adjacent components.

Q: How do the response frequency differences impact performance?

A: The substitute part operates at 1.5kHz versus the original 2.5kHz. This lower switching speed is suitable for standard industrial automation applications but may not meet requirements for high-speed conveyor systems or rapid-cycle production equipment. Confirm application switching speed requirements before selection.

Q: Are both parts RoHS compliant?

A: Yes, both the GX-MK12B-P-Z and GX-312MLK-B-P-Z are RoHS compliant, meeting environmental and regulatory standards for electronic component manufacturing.

Q: What is the advantage of the wider voltage range in the substitute part?

A: The GX-312MLK-B-P-Z accepts 10V ~ 30V input versus 12V ~ 24V for the original part. This broader tolerance provides operational stability across variable power supply conditions and reduces sensitivity to voltage fluctuations in industrial environments.
