The substitute part GX-304S-A-N-R maintains these core functional and mechanical characteristics while offering an active product status and enhanced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The GX-304S-A-N-R is the manufacturer-recommended substitute for the obsolete GX-3S-R. Both sensors maintain identical output configuration, shielding, body material, and ingress protection ratings. The substitute operates across an expanded supply voltage range (10V ~ 30V versus 12V ~ 24V), providing greater flexibility in power supply selection. The GX-304S-A-N-R carries active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. The increased sensing distance (0.84mm versus 0.6mm) and response frequency (4kHz versus 1kHz) represent enhanced performance characteristics suitable for modern industrial applications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both sensors share identical output type (NPN-NO, 3-Wire), shielding, stainless steel body construction, IP67 rating, and cable lead termination. The substitute operates within the original supply voltage range and maintains the same operating temperature specification.

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

A: The GX-3S-R has a sensing distance of 0.024" (0.6mm), while the GX-304S-A-N-R has a sensing distance of 0.033" (0.84mm). This difference must be evaluated against specific application requirements for object detection proximity.

Q: Does the GX-304S-A-N-R support the same supply voltage as the GX-3S-R?

A: The GX-3S-R operates at 12V ~ 24V, while the GX-304S-A-N-R operates at 10V ~ 30V. The substitute supports the original voltage range and extends compatibility to lower and higher supply voltages.

Q: What is the significance of the response frequency difference?

A: The GX-3S-R operates at 1kHz response frequency, while the GX-304S-A-N-R operates at 4kHz. The higher response frequency of the substitute enables faster detection cycles in applications requiring rapid object sensing.

Q: Are there packaging differences between these sensors?

A: The GX-3S-R is supplied with cable leads, while the GX-304S-A-N-R is packaged in a box. Both maintain identical cylindrical form factor and mechanical dimensions suitable for standard mounting applications.

Q: What compliance certifications apply to each sensor?

A: The GX-3S-R carries RoHS Compliant certification. The GX-304S-A-N-R carries ROHS3 Compliant certification, representing current regulatory standards for hazardous substance restriction.
