The TURCK BC3-S12-AP6X is a compact and efficient capacitive proximity sensor tailored for applications where non-contact detection of both solids and liquids is required in extremely limited spaces. It features a smooth cylindrical Ø12 mm housing for fast installation without threads, ideal for integration in tight mechanical assemblies, panel doors, tanks, and tubes. This sensor supports a 3 mm sensing range (flush) and delivers a PNP normally open (NO) output signal, making it suitable for sourcing digital PLC inputs. With 10–30 VDC supply voltage, IP67-rated housing, and integrated LED for switch status, the BC3-S12-AP6X is built to endure moisture, vibration, and contamination common in industrial settings. The sensor’s slim body and flush mount capability make it ideal for high-precision material detection on conveyor belts, filling machines, compact production lines, or in machine guarding zones where space is a constraint. Key Features: • Capacitive sensor for solid and liquid detection • 3 mm sensing range (flush mount) • Smooth Ø12 mm cylindrical housing (non-threaded) • Output: PNP normally open (NO) • Voltage: 10–30 VDC (3-wire) • IP67 environmental protection • LED status indicator for easy commissioning • Short-circuit and polarity reversal protection • Optimized for embedded or surface installation
