SUCH M18 inductive proximity sensor for sale online. It's an analog proximity switch that outputs 4 analog signals: 0-10V, 0-20mA, 4-20mA, and 0-10V+0-20mA, available with 15-30V DC power supply, optional detection distance of 5mm or 8mm, 2 connection methods (M12 connector or 2m PVC cable), and 2 installation types (flush/non-flush).
An analog inductive proximity sensor outputs a continuous signal proportional to the distance between the sensor and the metal target, while a standard proximity switch only provides an ON/OFF signal.
The M18 cylindrical housing allows for a longer detection range, better signal stability, and stronger anti-interference performance, making it suitable for industrial environments.
Voltage outputs are easy to interface but more sensitive to electrical noise, while current outputs (especially 4–20mA) offer better noise immunity and are preferred for long-distance signal transmission.
