GX-5SB Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The GX-5SB is a cylindrical inductive proximity sensor manufactured by Panasonic Industrial Automation Sales. This sensor operates as an NPN-NC (normally closed) 3-wire device with a sensing distance of 0.8mm, designed for industrial automation applications requiring reliable object detection in confined spaces. The GX-5SB is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new installations where this model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

The GX-305S-B-N serves as the manufacturer-recommended substitute for the obsolete GX-5SB. Substitution compatibility is determined by the following critical parameters that must remain consistent:

• Sensor Type: Both devices are inductive proximity sensors
• Output Configuration: Both operate as NPN-NC, 3-Wire outputs
• Voltage Supply Range: Both accept 10V ~ 30V input
• Operating Temperature Range: Both function across -25°C ~ 70°C
• Ingress Protection: Both maintain IP67 rating
• Package Style: Both are cylindrical sensors with cable lead termination
• Shielding: Both are shielded designs
• Material Composition: Both feature nickel-plated brass bodies

The GX-305S-B-N represents an evolution within the Panasonic inductive sensor product line, transitioning from the legacy GX series to the active GX-300 series while maintaining functional and electrical compatibility with the original GX-5SB specification.

Parameter Comparison

Engineering Selection Recommendations

The GX-305S-B-N is the appropriate selection for applications currently using or requiring the GX-5SB. The substitute maintains electrical and mechanical compatibility across all critical operating parameters. The GX-305S-B-N carries active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and system replacements.

The GX-305S-B-N exhibits improved response frequency performance (4kHz versus 1.5kHz) and a marginally reduced sensing distance (0.7mm versus 0.8mm). These characteristics represent refinements in the product line and do not compromise functional compatibility in standard industrial automation applications where the original GX-5SB was deployed.

Frequently Asked Questions (FAQ)

Q: Can the GX-305S-B-N directly replace the GX-5SB in existing installations?

A: Yes. Both sensors share identical output configuration (NPN-NC, 3-Wire), voltage supply range (10V ~ 30V), operating temperature range (-25°C ~ 70°C), and cable lead termination. The cylindrical package and IP67 rating are consistent across both models.

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

A: The GX-5SB provides 0.8mm sensing distance, while the GX-305S-B-N provides 0.7mm sensing distance. This 0.1mm reduction is within typical tolerance for industrial proximity sensing applications and does not affect compatibility in standard mounting configurations.

Q: Does the GX-305S-B-N offer any performance improvements?

A: The GX-305S-B-N operates at 4kHz response frequency compared to the GX-5SB at 1.5kHz, providing faster detection response. This enhancement is beneficial for high-speed automation processes without introducing compatibility issues.

Q: Are there compliance differences between the two models?

A: The GX-5SB carries RoHS Compliant status, while the GX-305S-B-N carries ROHS3 Compliant status. ROHS3 represents current regulatory compliance and is suitable for all applications requiring RoHS certification.

Q: What is the physical package difference?

A: Both models are cylindrical sensors with cable lead termination. No mechanical redesign or mounting modification is required for substitution.
