Key Parameters

Substitute Part Grouping Explanation

The GX-318MLK-B-P-Z qualifies as a functional substitute for the GX-MK18B-P-Z based on the following critical parameters:

Matching Parameters:

• Sensor Type: Both are inductive proximity sensors
• Output Type: Both feature PNP-NC, 3-Wire configuration
• Package / Case: Both use Cylinder, Threaded - M18 form factor
• Ingress Protection: Both meet IP67 and IP69K ratings
• Termination Style: Both use connector termination
• RoHS Status: Both are RoHS Compliant
• Material - Body: Both feature Nickel-Plated Brass construction

Differing Parameters:

• Sensing Distance: GX-318MLK-B-P-Z provides 0.504" (12.8mm) versus 9.6mm
• Voltage - Supply: GX-318MLK-B-P-Z operates 10V ~ 30V versus 12V ~ 24V
• Response Frequency: GX-318MLK-B-P-Z operates at 600Hz versus 1kHz
• Operating Temperature: GX-318MLK-B-P-Z range is -40°C ~ 85°C versus -25°C ~ 70°C
• Product Status: GX-318MLK-B-P-Z is Active versus Obsolete

The substitute part belongs to the GX-300 series and maintains mechanical and electrical compatibility within the M18 threaded sensor platform.

Parameter Comparison

Engineering Selection Recommendations

The GX-318MLK-B-P-Z is the designated substitute for the obsolete GX-MK18B-P-Z. Both components maintain RoHS compliance and identical ingress protection ratings, ensuring regulatory and environmental durability requirements are preserved.

The substitute part operates within an expanded voltage range (10V ~ 30V) that encompasses the original specification (12V ~ 24V), providing broader power supply compatibility. The extended operating temperature range (-40°C ~ 85°C) exceeds the original specification, supporting deployment in more demanding thermal environments.

The increased sensing distance (12.8mm versus 9.6mm) and reduced response frequency (600Hz versus 1kHz) represent functional differences that must be evaluated against specific application requirements. The M18 threaded connector form factor and PNP-NC output configuration remain unchanged, ensuring mechanical and electrical interface compatibility with existing installations.

Frequently Asked Questions (FAQ)

Q: Can the GX-318MLK-B-P-Z directly replace the GX-MK18B-P-Z in existing installations?

A: Mechanical and electrical interfaces are compatible. The M18 threaded connector form factor and PNP-NC, 3-Wire output configuration are identical. However, the increased sensing distance (12.8mm versus 9.6mm) may affect detection performance depending on application geometry and target material properties.

Q: What is the impact of the different sensing distances?

A: The GX-318MLK-B-P-Z provides a 33% greater sensing distance. Applications requiring precise detection at the original 9.6mm distance may require sensor repositioning or recalibration of detection logic.

Q: Are there voltage supply compatibility concerns?

A: The substitute part operates across 10V ~ 30V, which fully encompasses the original 12V ~ 24V specification. Existing power supply configurations will function without modification.

Q: How do the response frequency differences affect performance?

A: The substitute operates at 600Hz versus the original 1kHz. This represents a 40% reduction in maximum switching frequency. Applications requiring high-speed detection cycles must verify compatibility with this lower response rate.

Q: Is the substitute part currently available?

A: The GX-318MLK-B-P-Z is classified as Active product status with 874 units in stock, compared to the obsolete GX-MK18B-P-Z status.

Q: Are both parts RoHS compliant?

A: Yes, both the GX-MK18B-P-Z and GX-318MLK-B-P-Z are RoHS Compliant, maintaining regulatory compliance for industrial automation applications.
