Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the GX-4S-R?

A: The GX-4S-R is classified as obsolete. The GX-304S-A-N-R is the active equivalent that maintains functional compatibility while ensuring ongoing manufacturer support and availability.

Q: Are the sensing distances interchangeable between GX-4S-R and GX-304S-A-N-R?

A: The GX-304S-A-N-R operates at 0.84mm sensing distance compared to the GX-4S-R at 0.6mm. This represents a 0.24mm increase in detection range. Applications requiring the exact 0.6mm specification must evaluate whether the extended sensing distance is compatible with target object positioning and mounting geometry.

Q: Can the GX-304S-A-N-R operate on the same power supply as the GX-4S-R?

A: Yes. The GX-4S-R operates on 12V ~ 24V, which falls within the GX-304S-A-N-R supply range of 10V ~ 30V. The substitute part is fully compatible with existing power supply configurations.

Q: What is the difference in response frequency between these sensors?

A: The GX-4S-R provides 1kHz response frequency, while the GX-304S-A-N-R provides 4kHz. The higher response frequency of the substitute allows faster switching cycles and improved detection of rapidly moving targets.

Q: Are the physical packages identical?

A: Both sensors feature cylindrical form factor with cable lead termination. Mechanical mounting and connector compatibility should be verified against specific application requirements and enclosure design specifications.

Q: Does the GX-304S-A-N-R meet current compliance standards?

A: Yes. The GX-304S-A-N-R is ROHS3 compliant, meeting current regulatory requirements. The obsolete GX-4S-R was RoHS compliant under earlier standards.
