M30 Inductive Proximity Sensor - NPN NO/NC (Flush)

✨Features

✅ Flush (Shielded) Mounting: Designed with a shielded coil that restricts the magnetic field to the front of the sensor face. This allows the sensor to be mounted flush within metal brackets or machine blocks without causing false interference, which is critical for protecting the sensor in heavy-duty environments.
✅ High Precision Performance: Unlike standard models with 3-5% deviation, this series offers an enhanced Repeat Accuracy of < 1.0%, making it suitable for applications requiring precise positioning or gap monitoring.
✅ Extended Sensing Capability: Available in 10mm (Standard) or 15mm (Extended) ranges within the M30 flush footprint, providing a robust detection distance while maintaining a protected, low-profile installation.
✅ Heavy-Duty Construction: The Nickel-Copper Alloy housing provides excellent mechanical strength for the large M30 thread size, ensuring durability against physical impact and corrosion in harsh industrial settings (IP67).

FAQ

Q:Can this M30 sensor be embedded directly into a metal base?

A:Yes. This sensor features a Flush (Shielded) design, which means the sensing coil is shielded. You can mount it fully embedded in metal brackets or machine structures so the sensing face is level with the metal surface without causing false triggers. This mounting style saves space and effectively protects the sensor body from side impacts.

Q:What is the output type of this sensor? Can it drive a relay directly?

A:This model provides an NPN Output (Selectable NO or NC). It supports a maximum load current of 200 mA, which is sufficient to directly drive most standard industrial relays, signal indicators, or connect directly to PLC inputs. Please note the operating voltage range is 10 ... 30 VDC with a voltage drop of < 1.5 V.

Q:How accurate is this sensor, and is it suitable for harsh environments?

A:This is a high-precision model with a Repeat Accuracy of < 1.0% (Sr), which is superior to standard proximity sensors, making it ideal for precise positioning tasks. regarding durability, it is built with a rugged Nickel-Copper Alloy housing and a PBT sensing face. Rated IP67, it effectively resists water, oil, and dust ingress in temperatures ranging from -25 C to +70 C.
