Key Parameters

Substitute Part Grouping Explanation

The GX-308ML-B-N qualifies as a direct substitute for the GX-8MLB based on the following critical parameters:

Matching Parameters:

• Sensor Type: Both are inductive proximity sensors
• Sensing Distance: Both operate at 0.063" (1.6mm)
• Output Type: Both provide NPN-NC, 3-Wire configuration
• Voltage Supply Range: Both operate within 10V ~ 30V
• Package / Case: Both use Cylinder, Threaded - M8 form factor
• Termination Style: Both feature Cable Leads
• Shielding: Both are unshielded designs
• Ingress Protection: Both meet IP67 standard

Enhanced Specifications: The GX-308ML-B-N represents an active product with improved performance characteristics including higher response frequency (2kHz vs. 500Hz), extended operating temperature range (-40°C ~ 85°C vs. -25°C ~ 70°C), stainless steel body construction versus nickel-plated brass, and compliance with ROHS3 standards.

Parameter Comparison

Engineering Selection Recommendations

The GX-308ML-B-N is the manufacturer-recommended substitute for the obsolete GX-8MLB. Both sensors maintain identical electrical and mechanical interfaces, ensuring direct compatibility in existing circuit designs and mechanical assemblies. The GX-308ML-B-N offers active product status with current manufacturing support and enhanced environmental specifications. The stainless steel construction provides improved corrosion resistance compared to the nickel-plated brass body of the original part. Both components satisfy RoHS compliance requirements, with the substitute meeting the more recent ROHS3 standard. The increased response frequency of the GX-308ML-B-N (2kHz) and extended operating temperature range (-40°C ~ 85°C) provide operational advantages for demanding applications without compromising backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the GX-308ML-B-N directly replace the GX-8MLB in existing installations?

A: Yes. Both sensors share identical sensing distance (0.063" / 1.6mm), output type (NPN-NC, 3-Wire), supply voltage range (10V ~ 30V), and M8 threaded cylinder package. The mechanical and electrical interfaces are fully compatible.

Q: What are the key differences between these two sensors?

A: The GX-308ML-B-N features a higher response frequency (2kHz vs. 500Hz), extended operating temperature range (-40°C ~ 85°C vs. -25°C ~ 70°C), stainless steel body construction instead of nickel-plated brass, and ROHS3 compliance. The substitute also supports additional ingress protection ratings (IP67G, IP69K).

Q: Why is the GX-8MLB classified as obsolete?

A: The GX-8MLB has been discontinued by the manufacturer. The GX-308ML-B-N represents the current active product line replacement with equivalent core functionality and improved specifications.

Q: Are there any application limitations when switching from GX-8MLB to GX-308ML-B-N?

A: No limitations exist for applications within the original operating parameters. The substitute's enhanced specifications (higher frequency response, wider temperature range, superior corrosion resistance) make it suitable for more demanding environments while maintaining full backward compatibility.

Q: Does the material change from nickel-plated brass to stainless steel affect performance?

A: The material change improves corrosion resistance and durability in harsh environments. Both materials are suitable for the specified ingress protection ratings. Electrical performance and sensing characteristics remain equivalent.

Q: What is the inventory status for these parts?

A: GX-8MLB: 963 pieces in stock. GX-308ML-B-N: 1183 pieces in stock. Both are available as new original components.
