Product FAQ

What is the detection range of the M18 sensor, and how does it compare to M12 models? +
The M18 inductive sensor offers a significantly larger sensing envelope, with a nominal distance of 8mm for unshielded (non-flush) models. This is double the range of standard M12 models (typically 4mm), making the M18 ideal for applications with larger mechanical tolerances or where a greater safety gap is required between the sensor and the moving target.
Is the output logic (NO/NC) switchable on this 3-wire M18 sensor? +
For maximum circuit stability and simplicity, our M18 series features fixed output logic. We provide four dedicated SKU options: NPN NO, NPN NC, PNP NO, and PNP NC. Please select the specific logic required for your PLC or control system at the time of purchase to ensure "plug-and-play" compatibility without the need for manual configuration.
How does ambient temperature affect the sensing accuracy of this switch? +
Our sensors are engineered for thermal stability across industrial environments. Within the standard operating range of -25°C to +60°C, the detection distance fluctuation is maintained within ±10% (referenced at +23°C). For extreme conditions from -30°C to +65°C, the maximum variance remains under ±15%, ensuring consistent triggering and reliable position feedback year-round.
