Parameter Comparison

Engineering Selection Recommendations

The GX-MK30B-Z is classified as an obsolete product. The GX-330MLK-B-N-Z is an active product offering equivalent electrical and mechanical compatibility with the following considerations:

Mechanical Compatibility: Both sensors use identical M30 threaded cylindrical packaging with connector termination, ensuring direct mechanical interchangeability in existing mounting configurations.

Electrical Compatibility: Both sensors provide NPN-NC, 3-Wire output with identical signal logic. The GX-330MLK-B-N-Z accepts a broader supply voltage range (10V ~ 30V versus 12V ~ 24V), providing greater flexibility in power supply selection.

Environmental Compliance: Both sensors meet IP67 and IP69K ingress protection ratings and are RoHS Compliant, satisfying industrial automation environmental and regulatory requirements.

Product Status: Selection of the GX-330MLK-B-N-Z ensures access to an active product with ongoing manufacturer support, spare parts availability, and technical documentation, eliminating supply chain risks associated with obsolete components.

Frequently Asked Questions (FAQ)

Q: Can the GX-330MLK-B-N-Z directly replace the GX-MK30B-Z in existing installations?

A: Yes, from a mechanical and electrical interface perspective. Both sensors use M30 threaded cylindrical packaging with connector termination and provide identical NPN-NC, 3-Wire output configuration. However, the increased sensing distance (24mm versus 17.6mm) and lower response frequency (400Hz versus 500Hz) must be evaluated against specific application requirements.

Q: What is the primary difference between these two sensors?

A: The GX-330MLK-B-N-Z provides a longer sensing distance (24mm versus 17.6mm) and operates at a lower response frequency (400Hz versus 500Hz). The substitute also offers an extended operating temperature range (-40°C ~ 85°C versus -25°C ~ 70°C) and broader supply voltage tolerance (10V ~ 30V versus 12V ~ 24V).

Q: Are there any compatibility concerns with the connector termination?

A: Both sensors use connector termination with identical M30 threaded cylindrical form factors. Connector compatibility must be verified against the specific connector type and pin configuration used in the target application.

Q: Does the increased sensing distance of the GX-330MLK-B-N-Z affect application performance?

A: The longer sensing distance may require adjustment of sensor positioning or detection logic in applications where precise 17.6mm detection is critical. Applications tolerant of detection at distances up to 24mm will experience no performance degradation.

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

A: The GX-330MLK-B-N-Z operates at 400Hz versus the GX-MK30B-Z at 500Hz. This difference is relevant only in applications requiring detection of rapidly moving objects or high-speed switching cycles. Most industrial automation applications operate well within this frequency range.

Q: Are both sensors RoHS Compliant?

A: Yes, both the GX-MK30B-Z and GX-330MLK-B-N-Z are RoHS Compliant, meeting regulatory requirements for hazardous substance restrictions in electronic components.
