Key Parameters

Substitute Part Grouping Explanation

The GX-312MLK-A-P-Z qualifies as a functional substitute for the GX-MK12A-P-Z based on the following critical parameters:

Core Compatibility Criteria:

• Sensor Type: Both are inductive proximity sensors
• Output Type: Both provide PNP-NO, 3-Wire configuration
• Package / Case: Both use Cylinder, Threaded - M12 form factor
• Termination Style: Both use connector-based termination
• Ingress Protection: Both meet IP67 and IP69K ratings
• Material - Body: Both feature Nickel-Plated Brass construction
• Shielding: Both are unshielded designs
• Indicator: Both include LED indication

Allowable Parameter Variations:

• Sensing Distance: 5.6mm (GX-MK12A-P-Z) vs. 6.4mm (GX-312MLK-A-P-Z) — acceptable variance for applications with flexible detection range requirements
• Response Frequency: 2.5kHz vs. 1.5kHz — substitute operates at lower frequency, suitable for standard industrial switching applications
• Voltage Supply: 12V ~ 24V vs. 10V ~ 30V — substitute accepts wider input range, maintaining compatibility with original supply specifications
• Operating Temperature: -25°C ~ 70°C vs. -40°C ~ 85°C — substitute provides extended temperature range
• Product Status: Obsolete vs. Active — substitute is currently in active production

Parameter Comparison

Engineering Selection Recommendations

The GX-312MLK-A-P-Z is the designated substitute for the obsolete GX-MK12A-P-Z. Selection of this substitute is supported by the following factors:

Product Status & Availability: The GX-MK12A-P-Z is obsolete, whereas the GX-312MLK-A-P-Z is in active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts maintain RoHS compliance. The substitute achieves ROHS3 compliance, meeting current regulatory requirements for new system designs and replacements.

Mechanical & Electrical Compatibility: Identical M12 threaded cylindrical form factor, connector termination, and PNP-NO output configuration ensure direct mechanical and electrical integration into existing installations without circuit modification.

Environmental Ratings: Both sensors maintain IP67 and IP69K ingress protection ratings, confirming suitability for identical environmental conditions including high-pressure wash and submersion scenarios.

Operating Parameters: The substitute's wider voltage supply range (10V ~ 30V) and extended operating temperature range (-40°C ~ 85°C) provide enhanced operational flexibility compared to the original part, with no reduction in capability for the original specification range.

Frequently Asked Questions (FAQ)

Q: Can the GX-312MLK-A-P-Z be used as a direct replacement for the GX-MK12A-P-Z?

A: Yes. Both sensors share identical output type (PNP-NO, 3-Wire), M12 threaded cylindrical package, connector termination, and environmental ratings (IP67, IP69K). Mechanical mounting and electrical connection are directly compatible without modification.

Q: What is the difference in sensing distance between these two sensors?

A: The GX-MK12A-P-Z has a sensing distance of 5.6mm, while the GX-312MLK-A-P-Z has a sensing distance of 6.4mm. This 0.8mm difference is acceptable for applications where detection range flexibility exists. For applications requiring the exact 5.6mm specification, this parameter variance must be evaluated against system requirements.

Q: Does the lower response frequency of the substitute affect performance?

A: The GX-312MLK-A-P-Z operates at 1.5kHz compared to the original 2.5kHz. This lower frequency is suitable for standard industrial switching applications. Applications requiring response frequencies above 1.5kHz must be evaluated separately.

Q: Are there voltage supply differences I should consider?

A: The GX-MK12A-P-Z operates on 12V ~ 24V, while the GX-312MLK-A-P-Z accepts 10V ~ 30V. The substitute's wider input range is backward compatible with the original specification range, providing additional flexibility for systems with variable supply voltages.

Q: What is the temperature operating range difference?

A: The GX-MK12A-P-Z operates from -25°C to 70°C, while the GX-312MLK-A-P-Z operates from -40°C to 85°C. The substitute provides extended low and high temperature capability, beneficial for applications in extreme thermal environments.

Q: Is the M12 connector the same on both sensors?

A: Both sensors use M12 threaded cylindrical packages with connector-based termination. Mechanical and electrical connector compatibility is confirmed. Verify connector pin configuration matches your system requirements.

Q: What is the difference in RoHS compliance status?

A: The GX-MK12A-P-Z is RoHS Compliant, while the GX-312MLK-A-P-Z is ROHS3 Compliant. ROHS3 represents the current regulatory standard and is fully backward compatible with RoHS requirements.
