电容性接近传感器
**TURCK **capacitive proximity sensors can sense targets where a standard inductive proximity or photoelectric won"t work. They feature non-contact sensing of wood, glass, cardboard, plastics, concrete block, glue, thin wires, silicon wafers, liquid levels through a sight glass and other nonmetal material. **TURCK** embedded sensors are suitable for flush mounting in steel. They also feature solid-state output, high switching frequency and have no moving parts. **TURCK** capacitive sensors are available in DC, AC and intrinsically safe models.
