Parameter Comparison

Engineering Selection Recommendations

The GX-330MLK-B-N is the manufacturer-recommended substitute for the obsolete GX-N30MLB. Both components maintain RoHS compliance and share identical mechanical mounting interfaces (M30 threaded cylinder), ensuring direct physical compatibility in existing installations.

The GX-330MLK-B-N offers superior operational characteristics including extended temperature range (-40°C to 85°C versus -25°C to 70°C), broader supply voltage acceptance (10V to 30V versus 12V to 24V), and higher response frequency capability (400Hz versus 100Hz). The increased sensing distance (24mm versus 17.6mm) provides greater detection range flexibility for application requirements.

Active product status of the GX-330MLK-B-N ensures ongoing availability, technical support, and supply chain continuity for both new system designs and field replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the GX-330MLK-B-N directly replace the GX-N30MLB in existing installations?

A: Yes. Both sensors share identical M30 threaded cylinder mechanical form factors, NPN-NC 3-wire output configuration, and cable lead termination. Physical mounting and electrical interface compatibility are maintained. The increased sensing distance of the GX-330MLK-B-N may require application-specific validation if detection range is a critical constraint.

Q: What are the key electrical differences between these sensors?

A: The GX-330MLK-B-N accepts a broader supply voltage range (10V ~ 30V versus 12V ~ 24V) and operates at higher response frequency (400Hz versus 100Hz). Both maintain NPN-NC output logic and operate from the same supply voltage family, ensuring control circuit compatibility.

Q: Does the increased sensing distance affect substitution suitability?

A: The GX-330MLK-B-N provides 24mm sensing distance compared to 17.6mm in the original. This extended range is generally advantageous for detection applications. Applications requiring precise minimum sensing distance should evaluate whether the increased range introduces false detection scenarios in their specific mounting geometry.

Q: Are there environmental rating differences?

A: The GX-330MLK-B-N supports IP67, IP67G, and IP69K ratings, providing enhanced environmental protection compared to the GX-N30MLB IP67 rating. Both sensors meet the base IP67 specification for dust and water ingress protection. The extended temperature operating range of the GX-330MLK-B-N (-40°C ~ 85°C) accommodates more extreme industrial environments than the original (-25°C ~ 70°C).

Q: What is the product status significance?

A: The GX-N30MLB is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The GX-330MLK-B-N maintains active product status, ensuring continued manufacturing, technical documentation, and supply chain support for procurement and field service requirements.
