Turck BI2-CRS260-ADZ40X2-B1131S34 Inductive Proximity Sensor

The Turck BI2-CRS260-ADZ40X2-B1131/S34 Inductive Proximity Sensor is a high‑pressure, weld‑field immune device designed for non‑contact metallic object detection and piston position feedback in hydraulic and heavy industrial automation. It provides a 2 mm sensing distance with a Normally Open, 2‑wire AC/DC output, compatible with wide control circuits (AC 20–250 VAC or DC 10–300 VDC) and a maximum load of 400 mA (AC) or 300 mA (DC). Housed in stainless steel 1.4305 (AISI 303) with a smooth barrel and a 260 mm probe length, it carries IP67 protection and features reverse polarity and short‑circuit protection, alongside magnetic field resistance for both DC and AC fields. The S34 variant emphasizes a high‑pressure design suitable for automotive manufacturing, robotic welding cells, and other demanding hydraulic machinery, including environments with welding currents, vibration, or magnetic interference. The sensor is built for hydraulic cylinder position sensing and machine sequencing in PLC‑controlled systems, with dual LED status indicators to simplify diagnostics and a 7/8" male B1131, 3‑pin electrical connection for reliable field installation. Static pressures up to 200 bar and dynamic pressures up to 100 bar are within its capabilities, making it a robust replacement for hydraulic cylinder sensing, clamping systems, and metal forming equipment. Turck’s BI2‑CRS260 family is commonly used for piston position monitoring and high‑pressure feedback in hydraulic and automation environments.
