GX-8MB-R-C5 Equivalent & Substitute Parts

Part Overview

The GX-8MB-R-C5 is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales. This sensor operates as a shielded, cylindrical M8-threaded unit with NPN-NC output configuration and a 0.8mm sensing distance. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GX-8MB-R-C5 is determined by the following critical parameters:

• Sensor Type: Must remain inductive
• Output Configuration: Must maintain NPN-NC, 3-Wire output
• Voltage Supply Range: Must support 10V ~ 30V operation
• Package Form Factor: Must be Cylinder, Threaded - M8
• Termination: Must use Cable Leads
• Shielding: Must be shielded
• Ingress Protection: Must meet or exceed IP67

The GX-308M-B-N-R5 satisfies all mandatory substitution criteria. While the sensing distance increases from 0.8mm to 1.2mm and response frequency increases from 1kHz to 2kHz, these parameter changes remain within acceptable tolerance for equivalent functionality in most industrial applications. The substitute part offers enhanced environmental protection (IP67, IP67G, IP69K) and extended operating temperature range (-40°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

The GX-308M-B-N-R5 is the manufacturer-recommended substitute for the obsolete GX-8MB-R-C5. Both sensors maintain identical electrical interface specifications (NPN-NC, 3-Wire output; 10V ~ 30V supply voltage) and mechanical form factor (M8 threaded cylinder with cable leads). The substitute part carries active product status with current manufacturing support and inventory availability.

The GX-308M-B-N-R5 provides improved material specification (stainless steel versus nickel-plated brass), extended environmental protection ratings (IP67G, IP69K in addition to IP67), and broader operating temperature range. These enhancements represent forward compatibility improvements without introducing incompatibility with existing system designs.

Both parts maintain RoHS compliance and identical ECCN/HTSUS classifications, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the GX-308M-B-N-R5 directly replace the GX-8MB-R-C5 in existing installations?

A: Yes. Both sensors share identical output configuration (NPN-NC, 3-Wire), voltage supply range (10V ~ 30V), M8 threaded mechanical interface, and cable lead termination. Electrical and mechanical compatibility is maintained.

Q: What is the significance of the increased sensing distance (1.2mm vs. 0.8mm)?

A: The GX-308M-B-N-R5 detects metallic objects at a greater distance. Applications requiring detection at exactly 0.8mm must verify that the 1.2mm sensing distance does not create false triggers or missed detections in the specific mounting geometry.

Q: Why does the response frequency differ between these models?

A: The GX-308M-B-N-R5 operates at 2kHz versus 1kHz for the GX-8MB-R-C5. This faster response time is compatible with most industrial control systems and represents an improvement in switching speed capability.

Q: What material difference exists between these sensors?

A: The GX-8MB-R-C5 uses nickel-plated brass; the GX-308M-B-N-R5 uses stainless steel. Stainless steel provides superior corrosion resistance in harsh or wet environments, making it suitable for a broader range of industrial applications.

Q: Are both sensors RoHS compliant?

A: Yes. The GX-8MB-R-C5 is RoHS Compliant; the GX-308M-B-N-R5 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the inventory status for these parts?

A: The GX-8MB-R-C5 (obsolete) has 1034 units in stock. The GX-308M-B-N-R5 (active) has 643 units in stock and benefits from ongoing manufacturing support.
