GX-8MB-C5 Equivalent & Substitute Parts

Part Overview

The GX-8MB-C5 is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales, designed for non-contact detection applications with a 0.8mm sensing distance. This sensor features NPN-NC output configuration, operates across 10V to 30V supply voltage, and is housed in a shielded M8 threaded cylinder package. The product is classified as obsolete, making identification of compatible substitute components essential for system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GX-8MB-C5 is based on the following critical parameters that must remain consistent or compatible:

• Sensor Type: Inductive proximity sensor technology
• Output Configuration: NPN-NC, 3-Wire logic
• Package Form Factor: M8 threaded cylinder housing
• Shielding: Shielded design for electromagnetic interference rejection
• Supply Voltage Range: 10V ~ 30V compatibility
• Termination: Cable leads connection method
• Ingress Protection: IP67 minimum rating
• RoHS Compliance: Environmental regulatory requirement

The GX-308M-B-N-C5 qualifies as a substitute based on matching these core parameters while offering enhanced specifications in sensing distance, response frequency, operating temperature range, and material composition.

Parameter Comparison

Engineering Selection Recommendations

The GX-308M-B-N-C5 is the manufacturer-recommended substitute for the obsolete GX-8MB-C5. Both components maintain identical electrical output configuration (NPN-NC, 3-Wire), supply voltage range (10V ~ 30V), and mechanical form factor (M8 threaded cylinder). Both are RoHS compliant and feature shielded construction with cable lead termination.

The GX-308M-B-N-C5 is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity. The substitute provides enhanced performance specifications including extended sensing distance (1.2mm versus 0.8mm), faster response frequency (2kHz versus 1kHz), and expanded operating temperature range (-40°C to 85°C versus -25°C to 70°C). The substitute also supports additional ingress protection ratings (IP67G, IP69K) beyond the base IP67 specification.

For applications requiring the exact 0.8mm sensing distance of the original GX-8MB-C5, the extended 1.2mm range of the substitute must be evaluated against specific detection requirements. In most industrial applications, the increased sensing distance provides operational flexibility without compromising functionality.

Frequently Asked Questions (FAQ)

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

A: Yes, the GX-308M-B-N-C5 is mechanically and electrically compatible. Both sensors use identical M8 threaded cylinder packaging, NPN-NC 3-wire output configuration, and 10V to 30V supply voltage. Cable lead termination is identical on both models. The primary design consideration is the increased sensing distance (1.2mm versus 0.8mm), which must be verified against your specific detection gap requirements.

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

A: The GX-8MB-C5 has a sensing distance of 0.8mm, while the GX-308M-B-N-C5 has a sensing distance of 1.2mm. This means the substitute can detect objects at a greater distance from the sensor face. Applications with tight spacing constraints should verify that the 1.2mm range does not cause false triggers or detection of unintended objects.

Q: Are both sensors RoHS compliant?

A: Yes, both the GX-8MB-C5 and GX-308M-B-N-C5 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the advantage of the faster response frequency in the substitute?

A: The GX-308M-B-N-C5 operates at 2kHz response frequency compared to the 1kHz of the GX-8MB-C5. This faster response capability allows detection of more rapidly moving objects or higher-speed production line applications without missing detection events.

Q: Does the substitute support higher ingress protection ratings?

A: The GX-308M-B-N-C5 supports IP67, IP67G, and IP69K ratings, providing flexibility for applications requiring enhanced water and dust resistance. The original GX-8MB-C5 is rated IP67. Both meet the base IP67 requirement for sealed industrial environments.

Q: What is the operating temperature difference?

A: The GX-8MB-C5 operates from -25°C to 70°C, while the GX-308M-B-N-C5 operates from -40°C to 85°C. The substitute provides a wider temperature operating window, suitable for extreme environment applications including cold storage and high-temperature industrial processes.
