Turck BI2-CRS260-ADZ30X3-B3131S34 Inductive Proximity Sensor

The Turck BI2-CRS260-ADZ30X3-B3131S34 Inductive Proximity Sensor delivers reliable, non-contact detection of metallic objects and piston position in high-pressure hydraulic systems, with weld-field immunity that helps maintain sensing performance in environments with welding currents and vibration. It features a 2 mm sensing distance, a 260 mm stainless steel probe, and a 12.7 mm housing, with an IP67 enclosure and a 1/2" Microfast male connector (B3131), delivering normally open (NO) output in a 2-wire AC/DC configuration, and tolerates 20-250 VAC or 10-300 VDC supply, 3-400 mA current, and 20 Hz switching. The sensor is built from stainless steel 1.4305 (AISI 303), rated for static pressures up to 200 bar and dynamic pressures up to 100 bar, with reverse polarity protection and high magnetic field immunity, making it suitable for installation directly into hydraulic equipment in demanding automation applications. Common uses include piston position monitoring in hydraulic cylinders, clamp position verification, machine sequencing, and hydraulic cylinder feedback in automotive manufacturing, robotic welding cells, and other heavy-duty hydraulic machinery; alternate Turck part numbers 2689UA and 4275400UR denote matching variants.
