Overview

4mm inductive proximity sensor for magnetic metals (for non-magnetic metals, the detection range is reduced). With a long lifespan, shielded type installation, anti-interference capability, 1mm detection distance, and IP67 protection rating, the miniature proximity switch is suitable for the precise positioning of molds, precision machine tools, and robots.

FAQ

Q1: What types of metal objects can the 4mm 2-wire inductive proximity sensor detect? ❯

The inductive proximity sensor is designed to detect all types of metal targets, including steel, iron, aluminum, and other conductive metals. Detection distance may vary depending on the material and size of the target.

Q2: How do I choose between NO and NC output modes on this 2-wire inductive sensor? ❯

The inductive sensor supports both normally open (NO) and normally closed (NC) configurations. You can select the mode based on your control system requirements—NO is typically used for general detection, while NC is preferred for safety-critical applications.

Q3: Can the 4mm inductive proximity sensor work with both NPN and PNP control systems? ❯

Yes. Although it is a 2-wire sensor, it is designed to be compatible with both NPN and PNP inputs, making it easy to integrate into a wide range of PLCs and automation controllers.

Solid little sensor, fits anywhere

Ordered this inductive proximity sensor for a quick fix. Red LED is great for checking status while it's running. Signal is rock steady at speed. Smaller than expected but that actually made it easier to fit in the housing. Good buy for the price.
