产品优势
Compared with mechanical switches, TCO-3040AB proximity sensor eliminates physical wear through contactless detection, significantly extending service life over 10 million operations. The compact cylindrical housing (M18螺纹尺寸) allows flexible installation in confined spaces. Dual-output design (NO+NC) provides wiring flexibility for diverse control logic requirements. Consistent performance is maintained even in environments with oil mist, dust or electromagnetic interference. 922
工作原理说明
The operational principle involves an oscillator generating alternating electromagnetic field. When metallic objects approach within 40mm range, eddy currents induced in the target cause amplitude attenuation that triggers signal switching. This electromagnetic induction mechanism ensures reliable detection without physical contact, avoiding false triggers caused by vibration or surface contamination. The output circuitry features short-circuit and reverse polarity protection for enhanced reliability. 1826
选型指导
Multiple variants are available including DC 2-wire models (TCO-3040AL/BL) and AC versions (TCO-2040A/B). For different sensing distances, the TCA-3050 series (50mm) and TCB-3080 series (80mm) provide extended range options. All models share the same rugged IP67-rated housing, with cable or connector output configurations to suit various installation requirements. Technical parameters are clearly marked on the product label for easy identification. 41822
