Product Status: The GX-305S-A-N-R maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete GX-5S-R.

Regulatory Compliance: Both parts maintain RoHS compliance. The GX-305S-A-N-R achieves ROHS3 compliance, meeting current regulatory requirements for new installations and replacements.

Electrical & Mechanical Equivalence: Identical output configuration (NPN-NO, 3-Wire), supply voltage range (10V ~ 30V), operating temperature range (-25°C ~ 70°C), and environmental protection (IP67) ensure direct functional compatibility in existing circuit designs and mechanical assemblies.

Physical Form Factor: Both sensors utilize identical cylindrical package design with cable lead termination, supporting direct mechanical replacement without enclosure or mounting modifications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both sensors provide identical electrical output configuration (NPN-NO, 3-Wire), operate within the same supply voltage range (10V ~ 30V), and maintain the same operating temperature range (-25°C ~ 70°C). The cylindrical package design and cable lead termination are identical, supporting direct mechanical and electrical replacement.

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

A: The GX-5S-R provides 0.8mm sensing distance, while the GX-305S-A-N-R provides 0.7mm sensing distance. This 0.1mm difference falls within acceptable substitution parameters for inductive proximity sensors in this category and does not affect compatibility in standard industrial automation applications.

Q: Does the higher response frequency of the GX-305S-A-N-R affect compatibility?

A: No. The GX-305S-A-N-R operates at 4kHz response frequency compared to the GX-5S-R at 1.5kHz. The higher response frequency provides improved detection speed and does not create compatibility issues with existing control circuits designed for the original sensor.

Q: Are there packaging differences between these parts?

A: The GX-5S-R is supplied with cable leads termination, while the GX-305S-A-N-R is packaged in a Box. Both sensors utilize identical cable lead termination style, ensuring compatibility with existing wiring and connector interfaces.

Q: What is the compliance status of both sensors?

A: The GX-5S-R is RoHS Compliant. The GX-305S-A-N-R is ROHS3 Compliant, meeting current regulatory standards. Both sensors maintain IP67 ingress protection and identical environmental specifications.
