GX-3SB Inductive Proximity Sensor - Equivalent & Substitute Parts

Part Overview

The GX-3SB is an inductive proximity sensor manufactured by Panasonic Industrial Automation Sales, designed for non-contact detection in industrial automation applications. This sensor features a 0.6mm sensing distance with NPN-NC output configuration and operates across a 12V to 24V supply range. The product is classified as obsolete, making identification of suitable substitute components essential for system maintenance and new design implementations. The GX-3SB maintains full RoHS compliance and IP67 ingress protection for reliable operation in demanding environments.

Substitute Part Grouping Explanation

The GX-304S-B-N qualifies as a direct substitute for the GX-3SB based on the following critical parameters:

Core Compatibility Criteria:

• Sensor Type: Both are inductive proximity sensors
• Output Type: Both feature NPN-NC, 3-Wire configuration
• Shielding: Both are shielded designs
• Material - Body: Both utilize stainless steel construction
• Termination Style: Both employ cable leads
• Operating Temperature: Both operate across -25°C ~ 70°C
• Ingress Protection: Both maintain IP67 rating
• Indicator: Both include LED indication
• Package / Case: Both feature cylinder form factor
• RoHS Compliance: Both meet RoHS standards

Allowable Parameter Variations:

• Sensing Distance: GX-304S-B-N operates at 0.033" (0.84mm), representing a 0.24mm increase from the GX-3SB baseline
• Response Frequency: GX-304S-B-N provides 4kHz response, exceeding the GX-3SB's 1kHz specification
• Voltage - Supply: GX-304S-B-N accepts 10V ~ 30V, providing broader input range compatibility than the GX-3SB's 12V ~ 24V specification

Parameter Comparison

Engineering Selection Recommendations

The GX-304S-B-N is the manufacturer-recommended substitute for the obsolete GX-3SB. Both components maintain identical core functionality across output type, shielding, material construction, termination style, operating temperature range, ingress protection rating, and indicator configuration.

The GX-304S-B-N offers enhanced specifications in three areas: extended sensing distance (0.84mm versus 0.6mm), increased response frequency (4kHz versus 1kHz), and broader supply voltage acceptance (10V ~ 30V versus 12V ~ 24V). These enhancements provide greater operational flexibility without compromising the core sensing characteristics required for GX-3SB replacement applications.

The GX-304S-B-N carries active product status and meets ROHS3 compliance, ensuring long-term availability and alignment with current regulatory requirements. The component is available in box packaging with 743 units in current inventory stock.

Frequently Asked Questions (FAQ)

Q: Can the GX-304S-B-N directly replace the GX-3SB in existing installations?

A: Yes. Both sensors share identical output type (NPN-NC, 3-Wire), shielding configuration, stainless steel body material, cable lead termination, operating temperature range (-25°C ~ 70°C), IP67 ingress protection, and LED indicator. The GX-304S-B-N's broader supply voltage range (10V ~ 30V) accommodates the GX-3SB's 12V ~ 24V requirement.

Q: What is the significance of the increased sensing distance in the GX-304S-B-N?

A: The GX-304S-B-N provides 0.84mm sensing distance compared to the GX-3SB's 0.6mm. This extended range allows detection at greater distances from the target object. Applications requiring the original 0.6mm specification must account for this parameter difference during mechanical integration.

Q: How does the 4kHz response frequency of the GX-304S-B-N compare to the GX-3SB's 1kHz specification?

A: The GX-304S-B-N's 4kHz response frequency is four times faster than the GX-3SB's 1kHz specification. This enhanced response capability supports higher-speed detection cycles and faster switching applications without degradation of performance.

Q: Are there packaging differences between these components?

A: The GX-3SB is specified with standard packaging, while the GX-304S-B-N is supplied in box packaging. Both maintain identical cylinder form factor and mechanical dimensions for mounting compatibility.

Q: What is the compliance status difference between these sensors?

A: The GX-3SB carries RoHS Compliant status, while the GX-304S-B-N meets the current ROHS3 standard. ROHS3 represents the updated regulatory requirement for restricted substances in electrical and electronic equipment.
