TE Connectivity's proximity sensors detect the presence of metallic targets without physical contact, using an electromagnetic field that emerges from the sensor's active face. They have no moving parts and are designed for long-term, reliable operation in harsh industrial environments including humidity, vibration, dust, and chemical exposure. The product line covers cylindrical tubular sensors (M6 to M30 thread diameters), non-tubular flat-face sensors, and large-format sensors — all available in NAMUR (Ex i), DC (NPN/PNP), and AC output versions.
