Turck Bi2-CRS260-ADZ30X2-B3131 Inductive Proximity Sensor

The Turck BI2-CRS260-ADZ30X2-B3131/S34 inductive proximity sensor is a compact, high‑pressure, non‑contact cylinder position sensor designed for installation in hydraulic cylinders, pneumatic actuators, clamping systems, and metal forming equipment where reliable feedback is required under hydraulic pressure. It detects metallic targets at a sensing distance of 2 mm (0.08 in) and uses a 2‑wire normally open output with an operating voltage of 20–250 VAC or 10–300 VDC and a maximum switching current of 100 mA at up to 20 Hz. The flush‑mount, smooth barrel probe is made from stainless steel 1.4305 (AISI 303), with a 12.7 mm (0.50 in) diameter and 26 mm (1.02 in) length, and it carries a 200 bar static / 100 bar dynamic (2900 psi / 1450 psi) pressure rating. It is IP67 protected and features magnetic field resistance, reverse polarity protection, and short‑circuit protection, along with a red LED switching indicator for status. Electrical connection is via a 1/2" 3‑pin male connector, and installation is suitable for high‑pressure cylinder port mounting. Operating temperatures span −25°C to +70°C. Manufacturer part number BI2-CRS260-ADZ30X2-B3131/S34 (identification 4275493). Common replacements include Turck BI2-CRS343-ADZ30X2-B3131/S34 and BI2-CRS232-ADZ30X2-B3131/S34.
