Turck BI2-CRS232-ADZ30X2-B1131S34 Proximity Switch

The Turck BI2-CRS232-ADZ30X2-B1131/S34 Cylinder Position Sensor delivers non‑contact piston position sensing and high‑pressure cylinder monitoring in hydraulic and industrial automation systems. This inductive, weld‑field immune sensor is designed for direct installation into hydraulic equipment and features a 2 mm sensing distance with a 23.2 mm probe length, a normally open (NO) 2‑wire AC/DC output, and supply ranges of 20–250 VAC or 10–300 VDC; it uses a stainless steel 1.4305 (AISI 303) housing with a 12.7 mm diameter, is IP67 rated, and operates from -25°C to +70°C. The S34 variant targets robotic welding cells and heavy‑duty hydraulic applications, offering weld‑field immunity and magnetic‑field resistance, along with reverse polarity protection and short‑circuit protection with latching, plus an LED indicator (green power, red switching). Common applications include hydraulic piston position monitoring, clamp verification, machine sequencing, and end‑of‑stroke detection in PLC‑controlled systems, with a 200 bar static and 100 bar dynamic pressure rating and a 7/8" male connector (B1131), 3‑pin electrical connection.
