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

Part Overview

The GX-5S is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales, designed for non-contact detection of metallic objects at a sensing distance of 0.8mm. This cylindrical sensor operates with NPN-NO output configuration and is housed in a nickel-plated brass body with IP67 ingress protection rating.

The GX-5S is classified as obsolete. Locating equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement or new installations where this sensor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GX-5S is determined by the following critical parameters that must remain consistent:

• Sensor Type: Inductive (unchanged)
• Output Type: NPN-NO, 3-Wire (unchanged)
• Shielding: Shielded (unchanged)
• Material - Body: Nickel-Plated Brass (unchanged)
• Voltage - Supply: 10V ~ 30V (unchanged)
• Termination Style: Cable Leads (unchanged)
• Operating Temperature: -25°C ~ 70°C (unchanged)
• Ingress Protection: IP67 (unchanged)
• Indicator: LED (unchanged)
• Package / Case: Cylinder (unchanged)

The GX-305S-A-N is identified as the manufacturer-recommended substitute. This part maintains all critical electrical and mechanical parameters while offering improved specifications in sensing distance and response frequency.

Parameter Comparison

Engineering Selection Recommendations

The GX-305S-A-N is the manufacturer-recommended substitute for the obsolete GX-5S. Both sensors maintain identical electrical and mechanical compatibility across all critical parameters including supply voltage range, output configuration, operating temperature, and ingress protection rating.

The GX-305S-A-N offers active product status, ensuring ongoing availability and support. The substitute part demonstrates enhanced compliance with ROHS3 standards compared to the original RoHS Compliant designation of the GX-5S.

The sensing distance differential of 0.1mm (0.8mm versus 0.7mm) and the response frequency improvement from 1kHz to 4kHz represent specification enhancements in the substitute part. These changes do not compromise compatibility in applications designed for the GX-5S.

Frequently Asked Questions (FAQ)

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

A: Yes. The GX-305S-A-N maintains identical electrical output type (NPN-NO, 3-Wire), supply voltage range (10V ~ 30V), operating temperature range (-25°C ~ 70°C), and physical package configuration (cylinder with cable leads). The sensing distance difference of 0.1mm and increased response frequency do not prevent direct substitution.

Q: What is the significance of the sensing distance difference between the two parts?

A: The GX-5S operates at 0.8mm sensing distance while the GX-305S-A-N operates at 0.7mm. This 0.1mm reduction represents a minor specification change. Applications requiring the specific 0.8mm distance should evaluate whether the 0.7mm distance of the substitute part is compatible with their detection requirements.

Q: How do the response frequency specifications differ?

A: The GX-5S has a response frequency of 1kHz, while the GX-305S-A-N operates at 4kHz. The higher response frequency of the substitute part indicates faster switching capability and does not create compatibility issues for applications designed for the original 1kHz specification.

Q: Are there packaging differences between these parts?

A: The GX-5S is packaged with cable leads termination, and the GX-305S-A-N maintains the same cable leads termination style. Both parts are housed in cylindrical packages with identical mechanical dimensions and mounting configurations.

Q: What compliance certifications apply to each part?

A: The GX-5S carries RoHS Compliant certification. The GX-305S-A-N carries ROHS3 Compliant certification, representing an updated compliance standard. Both parts meet the same ingress protection rating (IP67) and environmental operating specifications.
